Hyper-V Fabric and Fabric Management Cluster

Dear All...........Would appreciate understanding of following:
What is the difference between Fabric Cluster and Fabric Management Cluster?
What virtual machines should be part of Fabric Cluster and Fabric Management Cluster respectively?
Thanks in advance.

It would be helpful if you provided a source from which you pulled those terms. They could mean just about anything without any context.
But I will take a stab at it based upon work I do with the Microsoft Private Cloud Fast Track program. In this reference architecture, a private cloud is being built. To manage the private cloud, a Hyper-V cluster is created and all the System
Center components required to manage the private cloud are installed on this cluster. This cluster is called the Fabric Management Cluster because from it all components of the Fabric, servers, storage, networking, VMs, policies, libraries, etc. are
managed.
Once that Fabric Management Cluster is established, any number of Fabric Clusters can be configured. For example, the Private Cloud could be configured for a business, and multiple business units have virtual systems deployed. The Fabric Management
manager could decide to build one large Fabric Cluster on which to deploy the various business unit machines, or the manager could create separate clouds, each consisting of its own Fabric Cluster. Each separate cloud could be dedicated to the use of
a single business unit.
Again, all conjecture on my part because you have not provided any context.

Hyper-V networking and connection manager software

Hi All,
I've just started running client hyper-v on windows 8.1 and have found a huge issue (well huge for me). We use iPass where I work to grant us access to wifi hotspots around the globe and also as a connection manager so it always uses the fastest/best connection.
However I have noticed that once you configure networking for hyper-v the ipass client looses sight of the ethernet card and can no longer detect it. As a result I've been getting stuck onto a public wifi hotspot when connected to ethernet in the office
as iPass doesn't see an ethernet device.
I've checked this by deleting the hyper-v network and rebooting and then iPass springs into life and disables both wifi and wwlan as it can see I have a lan connection. I've also tried this using vodafones mobile broadband software instead of iPass and found
the same issue exists.
It would appear that when hyper-v creates the virtual adaptor everything else looses access to the physical nic. right now I have removed networking from my local VMs but any help with this is greatly appreciated.
As ever, thanks in advance.
S

tried sharing and bridging neither work. as soon as the hyper-v network is created the hardware appears to be hidden from anything other than the OS.
This is only an issue if your creating a switch with external access. Creating an internal switch where you have access to the VMs from the local host is fine, so it seems related to whatever hyper-v is doing with actual network card.

Fabric Interconnect B, management services are unresponsive

Hi,
We have configured Call Home option in UCSM and we are getting below error from Call Home option since last Saturday. We have open TAC with Cisco to troubleshoot this error but as per TAC "The error is a transient error from which the fabric interconnects can automatically recover."
Below is the error messages we are getting

We want to understand that what is the impact of this error and is there anything that we can do to prevent this error? Also want to know what might be the cause get this error?
Let me know if anything else is needed from my side
show-tech file uploaded.

Padma,
TAC Engineer sent below mail
Hi Amit,
I’ve checked through the show tech you’ve uploaded and have not found any indicators of errors for the error message you are seeing.
As I mentioned in the call, the error is a transient error from which the fabric interconnects can automatically recover from. The recommended action is to wait for a few (10-15min) to see if the error clears automatically. If the error does not clear then we will need to do further troubleshooting. This error on its own is not a cause for worry. As you have HA in your system the management services would have failed over the to the other fabric interconnect and would not affect your system performance.
We can leave the system under observation for a few days to see if other errors occur concurrently with this error.
I will upload show-tech logs here, find my reply below
Is the alert generated only for FI B or both FIs ->> Amit: Alert generated for FI-B only
Any change in cluster state corresponding to alert time stamp ->> Amit: Unfortunately when this error generating we are unable to see the cluster state because of timing. If you can guide / suggest from any other location I can find the state that will be helpful
Cluster physical link status ->> Amit: Cluster link is OK
Does FI have any core dumps ->> Amit: I don't have any idea about this. How can check this ?

Amit Vyas

Monitoring traffic between UCS fabric extenders and fabric interconnect?

What is the best way to monitor the traffic between UCS fabric extenders (chassis) and fabric interconnect? Specifically I am looking for parameters to keep an eye on to determine when we may need to move from 2 links per fabric extender to 4 to handle greater IO needs.
Thanks.
- Klaus

One way you could monitor usage is by looking at the interface stats just as you would for any switch uplink.
Connect to the Cluster CLI
connect NXOS
Look at the input/output rate of your Server Uplink interfaces.
In my example I'm using fixed ports 1 through 4 on my FI's connecting to the IOM of the Chassis.
UCS-A(nxos)# show int eth1/1-4 | include rate
30 seconds input rate 17114328 bits/sec, 1089 packets/sec
30 seconds output rate 8777736 bits/sec, 693 packets/sec
    input rate 5.07 Mbps, 198 pps; output rate 1.03 Mbps, 99 pps
30 seconds input rate 2376 bits/sec, 0 packets/sec
30 seconds output rate 1584 bits/sec, 2 packets/sec
    input rate 1.58 Kbps, 0 pps; output rate 1.58 Kbps, 3 pps
30 seconds input rate 2376 bits/sec, 0 packets/sec
30 seconds output rate 31680 bits/sec, 20 packets/sec
    input rate 1.58 Kbps, 0 pps; output rate 30.89 Kbps, 18 pps
30 seconds input rate 2376 bits/sec, 0 packets/sec
30 seconds output rate 1584 bits/sec, 1 packets/sec
    input rate 1.58 Kbps, 0 pps; output rate 1.58 Kbps, 3 pps
If you notice your two links pushing near 10G consistently, it might be time to add another 2 link.
Other than this you can use SNMP to log the stats and look based on daily/weekly/monthly usage.

Guide to remote manage Hyper-V servers and VM's in workgroups or standalone

This guide is based on the following 3 products:
Windows server 2012 (core)
Windows 8
Hyper-V server v3 / Hyper-V server 2012
The following guide will enable you to:
1: remotely manage your Hyper-V Virtual Machines with Hyper-V manager
2: remotely manage your Hyper-V servers' firewall with a MMC snap-in.
3: remotely manage your Hyper-V server (2012) with server manager
! This should also work for Core installations of server 2012, but I haven't tried.
This guide is purely focussed on servers in a WORKGROUP, or as a stand alone.
I CAN NOT tell you what you need to do to get it working in a domain.
* You can run these commands straight from the console (Physically at the machine) or through RDP.
* You will need to be logged on as an administrator.
* Commands are listed in somewhat random order; I do however advise to follow the steps as listed.
* Commands with ? in front of them are only ment to be helpfull for troubleshooting,
* and to identify settings and changes made.
* Commands and instructions with ! in front of them are mandatory.
- server: means the server core or hyper-v server (non gui)
- client: means the machine you want to use for remote administration.
- Some commands are spread over 2 lines; be sure to copy the full syntax.
> To enable the Hyper-V manager to connect to your server, you need to perform the following 2 actions: (Assuming you have already installed the feature)
1:
! Client: Locate the C:\Windows\System32\Drivers\etc\hosts file.
! right-click --> properties --> security
! click --> edit --> add --> YOURUSERNAME or Administrator --> OK
! then select this new user, and tick the "modify"-box under the "allow"-section.
! apply the change, and close.
! doubleclick the file, and open with notepad
! add the ip-address and name of your server (no // or other crap needed)
! Save the file
# I recommend putting a shortcut to this file on the desktop.
# If you change the ip-address of your server (e.g. move the server from staging to a live environment)
# you might forget to do so in the hosts file.
# Hyper-V manager, MMC, RSAT, and Server-manager all rely on the hosts-file to resolve the name.
# some of these might connect to their respective service on an i.p.-level, but some don't.
# This is the main reason you need to modify this file.
! USE AN ELEVATED CMD/POWERSHELL PROMPT TO CONTINUE !
# the next config needs to be done on windows 8.
# It seems that it's already preconfigured under server 2012
2:
! Client: dcomcnfg
! open component services --> computers
! right-click -> my computer -> properties
! select "COM SECURITY" tab
! under "ACCESS PERMISSIONS" select "edit limits"
! select "ANONYMOUS LOGON", and tick "remote access" under ALLOW
# Without this adjustment, you can't connect to your Hyper-V server
# with the Hyper-V manager if you're not in a domain.
> And if you haven't done so already... make sure you have enabled remote management number 4 on the Hyper-V server console.
> Next, is to get the MMC firewall snap-in working.
The reason for this, is to have a GUI available to configure it.
If you're happy without it, you may skip this and use a shell instead to do so.
? server: netsh advfirewall show currentprofile
# shows the current profile (public/domain/private) and its settings
# depending on your needs, you should set the right profile to fit your needs.
# You can easily do this when the MMC snap-in is done. (after you've followed these steps)
! server: netsh advfirewall set currentprofile settings remotemanagement enable
# enables remote management of the firewall on an application level
# (In other words: allows the firewall to be remotely managed)
! server: netsh advfirewall firewall set rule group="Windows Firewall Remote Management" new enable=yes
# allows remote management of the firewall, through the required firewall ports with TCP protocol.
# 4 rules will be updated to allow access: public & Domain, dynamic and endpoint-mapper.
# You can disable/add/change the rule from the MMC snap-in after finishing this guide.
# e.g. set the firewall through the MMC-GUI to only allow specific ip-addresses etc.
? server: netsh advfirewall firewall show rule all
# Shows a list of available rules, and their current state.
# when run from cmd, the list exceeds the maximum length for review.
# (from cmd,type:) start powershell, and run the command from there.
! Client: cmdkey /add:YOURSERVERNAME /user:USERNAMEONTHESERVER /pass:THEPASSWORDOFTHATUSER
# I recommend you to use a username with enough privileges for management
# All capital letters need to be replaced with your input
# CMD answers "credential added successfully" when you're done
! Client: locate MMC, and run it as an admin.
# In windows 8/2012, go to search and type MMC. Right-click the icon,
# and choose run as admin on the bar below.
! Client: application MMC: select "file" --> Add/remove snap-in
! --> (left pane) scroll down to "windows firewall" --> select and click "add"
! select "another computer"
! type the name of the server you want to manage (NO workgroup/ or //, just same name as you typed for cmdkey)
* Part 2 is done.
# Have a look by doubleclicking the firewall icon in the left pane.
# It looks and works the same as the GUI version that you are familiar with.
! Next is the Server Manager.
# Follow the steps listed to get your server listed and manageable in the server manager.
! Client: Open the created Firewall snap-in for your server.
! Find the 3 "Remote Event Log Management" entries in the list of INBOUND rules, and enable them.
! Open powershell --> in cmd windows, type: start powershell
! run the following line in powershell
! Client: in C:\Windows\system32> set-item WSMAN:\localhost\client\trustedhosts -value YOURSERVERNAME -concatenate
# WinRM Security Configuration.
# This command modifies the TrustedHosts list for the WinRM client. The computers in the TrustedHosts list might not be
# authenticated. The client might send credential information to these computers. Are you sure that you want to modify
# this list?
# [Y] Yes [N] No [S] Suspend [?] Help (default is "Y"): y
# I recommend to choose yes; unless you like to pull some more hairs...
! server: winrm qc
# WinRM service is already running on this machine.
# WinRM is not set up to allow remote access to this machine for management.
# The following changes must be made:
# Configure LocalAccountTokenFilterPolicy to grant administrative rights remotely
# to local users.
# Make the changes? y / n
! select yes
! Client: open the server 2012 server manager
! click manage -> add server
! select the DNS tab, and type the name of your server
Done.
You can now manage your remote server through the familiar computer management GUI.
! Right-click your remote server, and select "Computer Management"
A few side notes:
? The Performance tab seems to list the local machine's performance, in stead of the remote servers'
? If you want Windows server backup, you need to right-click the server in the server manager, and select "add roles and features.
? it will then become available under the "computer management" of the remote server.
If you liked this guide you may thank my employer, Mr. Chris W.
for giving me the time to work it all out.
Cheers!

As a little update to the post, I'd like to add that replication, clustering and migration will not work in workgroup environments. Unless someone can provide an additional guide for this, I'd recommend anyone to no even bother to try.
To manage the standalone hyper-v server in a remote location over the internet, I would recommend the following:
Install windows 8 pro (x86 uses less resources!) as a vm on the host, and assign 2 network connections to it.
1 external (shared with host) (be sure you have a dedicated ip-address for it!)
1 internal connection.
What I did was this:
As soon as you've installed the win8 guest, proceed with the guide as described.
For the 1st step of the guide (hosts-file) use the ip-address you will later assign to the "internal" network switch of the host!
In my example, I'm using 10.0.0.1 for the host, and 10.0.0.2 for the guest.
To be clear: I first used the guide on a LAN-environment, and did all the steps from a "real" client to server on the LAN.
Then, installed the win8 guest on the host using the "real" clients' hyper-v manager over the LAN.
Next, assigned the 2 network connections to the VM, and configured them as follows:
external - as you would to be able to make your guest reach the internet.
internal - I used the following config:
ip-address: 10.0.0.2
subnet: 255.255.255.252
gateway - blank
dns - Blank
Now, when you get to the console of the hyper-v server (host) or RDP to it, go to network settings.
You'll see that the internal card has been added here as well.
Configure it as follows:
ip-address: static - 10.0.0.1
subnet: 255.255.255.252
gateway - blank
dns - blank
You should now be able to ping your guest (win8) on 10.0.0.2 if it's running.
Don't forget to enable ping response (option 4 on the host) to test connectivity the other way around as well (guest to host)
When you're done, you'll be able to RDP to the guest OS over the internet, and then connect to the host with server manager, hyper-v manager, and MMC.
Don't forget to enable each module on the hosts' firewall to make the snap-ins work!
Remote volume management requires your guest/client firewall INcoming ports to be enabled as well! not just the host.
Either update the firewall rules from the MMC gui as described in the guide, or use the following commands on the
hosts' powershell:
Enable the firewall rules with the command Enable-NetFirewallRule -DisplayGroup "USE_THE_COMMANDS_BELOW" (include the " " in the command)
Remote Service Management
Remote Volume Management
Remote Event Log Management
Remote Scheduled Tasks Management
Windows Firewall Remote Management
Windows Remote Management
You can get the list with Get-NetFirewallRule -DisplayName *management*
You can get the list with Get-NetFirewallRule -DisplayName *remote*

How to remove HP ink from hands and fabrics

How to remove HP ink from hands and fabrics
Please note that the ink used by HP is a water based ink that will clean easily. Here’s how to remove ink stains from hands and fabric.
NOTE: IMMEDIATELY rinse the stained area with COLD water, and then follow the appropriate instructions.
To remove ink stains from hands:
Wash hands with an abrasive (gritty) soap. Note: It may take several washings.
To remove ink stains from white fabrics:
If ink from an HP Inkjet print cartridge spills on white fabric, use chlorine bleach and cold water to remove the stain, but act quickly.
CAUTION: Use only COLD water. Warm or hot water will "set" the color into the fabric.
To remove ink stains from colored fabrics:
Use sudsy ammonia—a dilute mixture of detergent and ammonia—and cold water. Act quickly and test on an inconspicuous area first.
CAUTION: Use cold water. Warm or hot water will "set" the color into the fabric.
WARNING: Do not mix ammonia and chlorine bleach; this creates a toxic gas!

I'm involved in fashion and would like to know which Adobe program would be suitable for importing images and my company logo to design fabric and send as image to fabric printers? Thanks

I'm involved in fashion and would like to know which Adobe program would be suitable for importing images and my company logo to design fabric and send as image to fabric printers? Thanks

Adobe Illustrator. Your company logo should be a vector file. Image files can be "Placed" in Illustrator. Artwork created for printing can be drawn in Illustrator and saved as .ai, .eps, and .pdf files which can be imported into your printer's RIP. But, check with your print vendors and see what they require. This does not rule-out Photoshop, however Photoshop can be limited. So, it would be a good idea to have Photoshop and Illustrator loaded in your workstation with Illustrator being the go-to application.

Nexus 7000, 2000, FCOE and Fabric Path

Hello,
I have a couple of design questions that I am hoping some of you can help me with.
I am working on a Dual DC Upgrade. It is pretty standard design, customer requires a L2 extension between the DC for Vmotion etc. Customer would like to leverage certain features of the Nexus product suite, including:
Trust Sec
VDC
VPC
High Bandwidth Scalability
Unified I/O
As always cost is a major issue and consolidation is encouraged where possible. I have worked on a couple of Nexus designs in the past and have levergaed the 7000, 5000, 2000 and 1000 in the DC.
The feedback that I am getting back from Customer seems to be mirrored in Cisco's technology roadmap. This relates specifically to the features supported in the Nexus 7000 and Nexus 5000.
Many large enterprise Customers ask the question of why they need to have the 7000 and 5000 in their topologies as many of the features they need are supported in both platforms and their environments will never scale to meet such a modular, tiered design.
I have a few specific questions that I am hoping can be answered:
The Nexus 7000 only supports the 2000 on the M series I/O Modules; can FCOE be implemented on a 2000 connected to a 7000 using the M series I/O Module?
Is the F Series I/O Module the only I/O Module that supports FCOE?
Are there any plans to introduce the native FC support on the Nexus 7000?
Are there any plans to introduce full fabric support (230 Gbps) to the M series I/O module?
Are there any plans to introduce Fabric path to the M series I/O module?
Are there any plans to introduce L3 support to the F series I/O Module?
Is the entire 2000 series allocated to a single VDC or can individual 2000 series ports be allocated to a VDC?
Is Trust Sec only support on multi hop DCI links when using the ASR on EoMPLS pwire?
Are there any plans to inroduce Trust Sec and VDC to the Nexus 5500?
Thanks,
Colm

Hello Allan
The only IO card which cannot co-exist with other cards in the same VDC is F2 due to specific hardware realisation.
All other cards can be mixed.
Regarding the Fabric versions - Fabric-2 gives much bigger throughoutput in comparing with Fabric-1
So in order to get full speed from F2/M2 modules you will need Fab-2 modules.
Fab2 modules won't give any advantages to M1/F1 modules.

- No link between IOM port 3/2/2 and fabric interconnect B:1/18

Specifically I'm trying to find out what the 3/2/2 means in - No link between IOM port 3/2/2 and fabric interconnect B:1/18

This from the fault reference guide:
"No link between IOM port [chassisId]/[slotId]/[portId] and fabric interconnect [switchId]:[peerSlotId]/[peerPortId]"

7600 / SUP720-3BXL - mixing fabric and non-fabric enabled line cards

Dear All,
I am having to mix fabric and non-fabric enabled line cards on a single chassis.
These are my line cards:
WS-X6704-10GE
WS-X6408A-GBIC
WS-X6148-GE-TX
What's the maximum expected throughput in running with mix fabric line cards ?
Also, what will be the optimal and the recommended switching mode to run (truncated vs. bus-mode) ?
Any inputs will be greatly appreciated.
egards,
ZH

hi!
The maximum throughput will depend on the ingress and the egress card for the traffic. i.e. If the traffic is coming on the fabric enabled card and going out on the same, then the throughput is would be equal to the fabric card ( 20 gbps duplex). But if there is a non fabric card either in the ingress or egress path, then the throughput would be limited by the non-fabric card.
As for the mode to run in, I dont think you would have to worry on that as a fabric card would default to truncated mode where-as the non-fabric cards would run in the bus mode. This works fine, as if the ingress to egress is a fabric card, only the header is sent to the superviser for processing using the tuncated mode and the packet is just sent on the fabric directly to the egress port.
If there is a communication between fabric-non-fabric cards, then the fabric card still uses truncated mode to get the packet processed by the L2/L3 engines on Superviser and then if the egress is a non fabric card, then the packet is sent over the fabric to the superviser. From there the packet is sent to the egress over the bus.

Is FC analyser and Fabric analyser the same thing?

Folks,
Is FC analyser and fabric analyser in MDS series switches the same thing. I am confussed. Also,
Does the FC analyser has a Test based ( Etherreal) and GUI based interface? has anyone installed the GUI interface? which one is better?

The Cisco "Fabric Analyzer" that is included with the MDS is a tool for monitoring control traffic on the switch - in other words, anything that passes through the Supervisor module. It has both interfaces, or you can export the traffic to a file and look at it later with another GUI (ethereal) if you like.
You can also use a SPAN port to monitor all traffic on a specific port. Perhaps this is what you are referring to as "FC Analyzer". Typically you would use a PAA to capture the traffic using ethereal or maybe a hardware protocol analyzer. ($$$!)
So, to answer your question - No, they are not the same thing (if my assumption about your description is correct).

Deployed BP for retail store and inventory management

Hi,
I have installed BP for retail which gives me the pages of store and inventory management but the iViews are not opening even after assignig the roles to the users. I have created the system alias SAP_ECC_RETAIL but still no luck.
Please help.
Thanks.

Hi,
Please check the following:
1. Ensure the BP for Common Parts is installed on the portal. This package is a prerequisite for the retail BP that u mentioned.
2. Make sure the system object that u created for the backend have passed the connection tests.
3. If this does not solve the issue, please check out the defaultTrace and application.log files under the following directory:
/usr/sap/SID/JC<NN>/j2ee/cluster/server0/log
Check the latest files here and post the error mssgs from there to this forum.

1-to-1 Relationship Between UI and subVI Data Cluster

Discussion continued from here.
In summary:

Yes,
I can see clear benefits in implementing this Idea - that is, if your
underlying datatype elements have a 1:1 relationship with the UI
elements.
I will
illustrate this point by showing some potential flaws in your example:
"Profile Running" and "Profile Complete" are mutually exclusive, no?
Wouldn't it be better to have a single enum named "Profile" with three
elements "Idle, Running, and Complete" for the underlying datatype?
Having two mutually exclusive pieces of data in an underlying datatype
is among my favorite of code smell indicators.
Also, the underlying datatype probably only needs "Forward Miles" and
"Reverse Miles" since "Total Miles" is derived. Exclude "Total Miles"
from the underlying cluster and just show the sum for display.
Another
argument against using a 1:1 relationship: the customer now wants to
multiply speed by -1 if Direction==Reverse and not show the Direction
enum on the UI. The data source (the VI that generates the data) would
need to be updated using your 1:1 relationship. Using underlying data
different from the display data, only the data client (the UI front
panel) needs to change. I would be much more inclined to service the UI
FP for a cosmetic upgrade rather than tracing the data source back
through the HMI framework, through TCP, back to the RT, back to FPGA...
Basically...
I question a perfectly overlapped Venn Diagram where the set of data
shown to the user equals the dataset used for underlying data
processing/messaging/storing. The underlying datatype should be as
stripped and streamlined as possible, while the display datatype can
inherit all the flair and post-processing that Upper Management wants to
see in a UI.

The data you see maps directly to tags on the PLC.

***EDIT: By all means, please start a discussion on the LabVIEW board so we're not hindered by the Exchange's interface. ***
My long delayed response:
The indicators you see map to tags on the PLC. That is, we were connecting through OPC to an application on a PLC that was written ~15 years ago. I have a VI where I read a bunch of SVs (Shared Variables). Each SV is bound through OPC to a PLC tag. In the interest of disclosure, two 16-bit tags are required to represent each 32-bit mileage number. In the same subVI, I read each set of mileage tags, convert, and feed my subVI cluster indicator. The same is true for wheel size: three bits get converted to the enum. Regardless, though, I have one subVI that reads SVs and outputs the same "underlying data" cluster that is seen on the UI. The UI has a "Faults" cluster full of fault Booleans that follows the same logic. When the user configures a profile of steps, they do so via an array of "step" clusters (although the cluster look is hidden for aesthetics). It's the same thing as above except we write tags instead of reading them.
In my case, each set of 16-bit tags is worthless as two 16-bit numbers. They are only useful as a 32-bit mileage, so I don't pass around the raw 16-bit data. The same is true for the wheel size bits. My software can just as easily (in fact, more easily) operate on the enum. So, the underlying cluster from the subVI is programmatically useful and applicable to the UI. I would guess that the same is true for a lot of RT applications, where the read VI can have some intelligence to process the data into useful / applicable clusters.
There are going to be cases where "Upper Management" would like to see "flair and post-processing" as you say. Your speed illustration is a good example of this. There are also instances where the cluster works fine on the UI the way it is (like this one and many others that we've seen).

<LabBEAN response
Did you mean "not" mutually exclusive? We combined 3 "dependent" (not mutually exclusive) Booleans into an enum for Wheel Size, as I mentioned above. Not sure now why we went the other way with these two (this was 2 years ago). In any event, with regard to UI representation, I still pass a cluster out of my read-raw-data-and-process-into-cluster subVI up to the applicable queued state machines and to the UI.

<LabBEAN response
Working with applications written in ladder logic, it is not uncommon to see separate Booleans that indicate the same condition. This seems to be especially true when safety is a concern. That is, ladder Coil A ON and Coil B OFF == switch open. Coil A OFF and Coil B ON == switch closed. If you ever read OPC tags from Coil A and Coil B and the two are the same, you know the ladder is in transition (hasn't updated the tags). Throw that point out and read again.
I, too, appreciate our back-and-forths. Good discussion.

Separate Views from Implementation for Strict Type Defs

Thanks for replying, Jason. Let me see if I can craft a coherent response after getting back up to speed...
(...later)
OK, let's go. I'm going to fully agree with you that LabVIEW imposes a strange constraint unique from most other languages where a Typedef defines two things: the underlying data structure, and also the view. A Strict Typedef should be more accurately deemed the Datatype-View-Definition, and a Typedef would be more accurately called the Datatype-Definition-and-View-Suggestion. And to be clear, there are two types of views: the programmer's view (a SubVI look and feel) and the UI view (what the user and Upper Management sees). (Finally, I admit I'm ignorant whether view or View is more a more appropriate term)
Linking the programmer's view to the datatype is perfectly fine with me, and based on your original Idea I think we both agree that's OK. I think we run into a disagreement where you have loosely tied the concept of "Strict TD" to "UI View".
Historically, I have used Strict Typedefs for the programmer's view (SubVIs), since I like to maintain a "functional UI" at the SubVI level. I don't use type definitions on User Interfaces - only Controls. That's the reason your Idea does not appeal to me, but perhaps if your Idea were implemented, it would appeal to me since View and Implementation would be divorced as separate entities within the Type Definition. (Does that classify as a Catch-22?) So, you're Idea is fundamentally suggesting that Type Definition .ctl files should be more accurately called "a container that holds both a Type Definition and any number of View Definitions as well".
Fundamentally, I think I finally understand the gist of your Idea: "let's ditch this weird constraint where View and Datatype are inextricably defined together in one file", and for that, I'll give Kudos to the original Idea. I got really tied up with the example you used to present the Idea, and plus I'm still learning a lot.
Additional thoughts:
This Idea reminds me of another: Tag XControl as Class View
We've still got some arguing to do on a 1:1 relationship between underlying datatype and UI presentation, so put your mean face back on:
Since our last conversation, interestingly, I have been on an anti-Typedef kick altogether. Why don't you drop some feedback on my attempt at a completely typedef-free UI framework?

Hyper V Lab and Live Migration

Hi Guys,
I have 2 Hyper V hosts I am setting up in a lab environment. Initially, I successfully setup a 2 node cluster with CSVs which allowed me to do Live Migrations.
The problem I have is my shared storage is a bit of a cheat as I have one disk assigned in each host and each host has starwinds virtual SAN installed. The hostA has an iscsi connection to hostB storage and visa versa.
The issue this causes is when the hosts shutdown (because this is a lab its only on when required), the cluster is in a mess when it starts up eg VMs missing etc. I can recover from it but it takes time. I tinkered with the HA settings and the VM settings
so they restarted/ didnt restart etc but with no success.
My question is can I use something like SMB3 shared storage on one of the hosts to perform live migrations but without a full on cluster? I know I can do Shared Nothing Live Migrations but this takes time.
Any ideas on a better solution (rather than actually buying proper shared storage ;-) ) Or if shared storage is the only option to do this cleanly, what would people recommend bearing in mind I have SSDs in the hyper V hosts.
Hope all that makes sense

Hi Sir,
>>I have 2 Hyper V hosts I am setting up in a lab environment. Initially, I successfully setup a 2 node cluster with CSVs which allowed me to do Live Migrations.
As you mentioned , you have 2 hyper-v host and use starwind to provide ISCSI target (this is same as my first lab environment ) , then I realized that I need one or more host to simulate more production scenario .
But ,if you have more physical computers you may try other's progects .
