System VLANs for AD, vCentre...

Hi All,
In the event that my entire data centre were to shut-down, is it recommended that the VLANs for AD, vCentre, vCentre DB be configured as System VLANs so that when everything powers up the VEM modules can actually communicate with these systems in order to get their configs? I am aware that the system vlans pretty much negate any security applied to them however was looking to see the best practice.
thanks,

Yeah it wouldn't be a bad idea. Just make sure to add the system vlan to the eth and veth port-profiles.
And remember you can only have 32 port-profiles with the system vlan command in them.
Also understand that when the VSM is not available to program the VEMs and a system vlan is present on the port-profiles that it is only basic connectivity that is allowed. No higher level features like ACLs or QOS will be working.
Let us know if you need more classification. You can also play with the concept if you want by building a small lab environment. The great thing about the N1KV is it does work on a nested ESXi environment so you can build an entire lab on one host.

Only system vlans forward traffic on 1000v

I am trying to migrate to a Nexus 1000v vDS but only VM's in the system VLAN can forward traffic. I do not want to make my voice vlan a system VLAN but that is the only way I can get a VM in that VLAN to work properly. I have a host with its vmk in the L3Control port group. From the VSM, a show module shows the VEM 3 with an "ok" status. I currently only have 1 NIC under the vDS control. My VM's using the VM_Network port group work fine and can forward traffic normally. When I put a VM in the Voice_Network port group I lose communication with it. If I add vlan 5 as a system vlan to my Uplink port profile then the VM's in the Voice_Network work properly. I thought you shouldn't create system vlans for each vlan and only use it for critical management functions so I would rather not make it a system vlan. Below is my n1k config. The upstream switch is a 2960X with the "switchport mode trunk" command. Am I missing something that is not allowing VLAN 5 to communicate over the Uplink port profile?

System vlan an port-profile

I have a profile uplink which include a system vlan of 50, 60, 220
thne i also have a port profile for vlan 50 and 60
but when i connect a vm to this port group, i do not get any connection.
however other vlans that are not set as system vlan on the uplink are working fine on their own port group.
any idea why?

here is an example from my configs I use.
port-profile type ethernet system-uplink-03
vmware port-group
switchport mode trunk
switchport trunk native vlan 1034
switchport trunk allowed vlan 1031-1034
channel-group auto mode on mac-pinning
no shutdown
system vlan 1031-1033
description Development system profile for critical ports and vm traffic
state enabled
1031-1034 are vmware mgmt, ip storage and vmotion in this instance vcenter was in a different environment I have I think about 12 different system uplink port profiles
here is a port-profile:
port-profile type vethernet 03-development-vmsc
capability l3control
vmware port-group
switchport mode access
switchport access vlan 1031
no shutdown
system vlan 1031
max-ports 32

hope this helps.

System VLAN's on n1000v

Hi all
when deploying the VSM on a Standard Switch, is it a requirement to include System VLAN's for my the packet and control VLAN's in the Port-Profiles on the dvs?
Many thanks

Correct. You only want system VLANs on the VLANs that are needed to bootstrap the 1000v.
The normal port-profiles that would be used with your VMs typically don't require a system VLAN.
In fact, if you enable a system VLAN on an interface that is going to implement access lists or QoS and there is a problem programming the interface, the port will still forward on that system VLAN, but none of the access lists or QoS settings will be in place.

Problem in creation of system alias for bw system

Hi,
I want to create system alias for the bw system

Hi Krishna,
I checked the connection settings.
WAS settings in system object is giving this mistake
before user mapping it works fine.
after giving usermapping i ma getting this exception.
SAP Web AS Connection
Test Details:
The test consists of the following steps:
1. Check the validity of the system ID in the system object
2. Check whether the system can be retrieved
3. Check whether a SAP system is defined in the system object
4. Validate the following parameters: WAS protocol; WAS host name
5. Check HTTP/S connectivity to the defined backend application
Results
1. The system ID is valid
2. Retrieval of the system was successful
3. The system object represents an SAP system
4. The following parameters are valid: Web AS Protocol (http) Web AS Host Name (172.19.18.75)
5. HTTP/S connection failed
for testing the connector i am getting this exception
Test Connection with Connector
Test Details:
The test consists of the following steps:
1. Retrieve the default alias of the system
2. Check the connection to the backend application using the connector defined in this system object
Results
Retrieval of default alias successful
Connection failed. Make sure user mapping is set correctly and all connection properties are correct.

Error 64 is being returned which is simply "the network name is no longer available".
There can be a number of reasons for this from SMB compatibility issues (2003 servers wont support SMB2), to the expected and actual computer name of the boxes don't match (tries to authenticate with server.tld.com when the actual name is srv-01.tld.com and
you just put a C-name in). I'd start from the top: Try opening said share from the Primary Site server as that's the box doing the work. Verify the IP and computer name is legit and that no one has played ACL games between the two systems (remember
RPC only initiates/listens on port 135 but established connections are up in the dynamic port range).
At the end of the day it's an issues "underneath" SCCM, and not an SCCM problem specifically.

What are the minimum system requirements for GB 4?

What are the minimum system requirements for GB 4? I did search this forum but wasn't able to find a direct answer.
I'm running version 3.0.4 successfully on a lowly G4 733 but I suspect this is as far as I can go.
I'm updating to iDvd'08 and was also wondering if I can safely update to GB4 or not (from GB 3.0.7) on a G4 733 mhz Digital Audio. Any help would be sincerely appreciated. My guess is that I cannot but I'd like to confirm prior to attempting any further updates in GB.

I try my best to play it safely; always. And you were right, everything worked on the ext. FW HD flawlessly ...... truly amazing software!
(I did happen to check the activity Monitor w/in Utilities and it showed GB4 using about 60-67% of the CPU on a G4 733 ..... I'm assuming this is normal).

Not sure if there's a correct order to opening these apps as there has been in former versions of iLife ..... however, this (as shown above) is the order in which I opened all apps, and all worked well.

What are the requirements in terms of system drive for visual studio 2013

the system drive. This link "visualstudio.com/products/visual-studio-professional-with-msdn-vs#Fragment_SystemRequirements" states the system requirement for visual studio pro 2013. However can somebody clarify what is needed in terms of system drive
requirement e.g. out of the 20 gb, how much is needed on the system drive.
Thanks

Hi,
Exact space required will vary widely based on installation components chosen and what you may have already installed on your system.
And When you install your VS in another Drive and run the VS installer, you can see system requirement in installation screen.
Because my work computer only have C Drive, I test the VS2012 professional installation in my home computer E drive. The Screen below:
I think the system requirement can also display when you install VS 2013.

System copy for PI 7.0 system

Hi,
We are doing system copy for complete landscape and every time we used to perform PI system copy using SAP standard procedure of backup/restore, Java exp/imp.
But can we use another approach of exporting IR/ID from source to Target. Because we do not have any transactional data in PI and what are different things that we need to take care if we export individual components.
Like new ports, we20,we21, IDX1,IDX2
Thanks,
Venkat.

to elaborate more,
we are doing system copy from Dev to Sandbox (we already have working sand box)
I am planning below steps
1) export all the software components from development system - Integration repository and Directory
2) Adjust the transport path in SLD (source Dev and target Sandbox)
3) Import the software components to Sandbox for Integration repository and Directory.
4) change user-passwords to match sandbox authentication.
Please let me know if i am missing any steps and has any one did a copy by above procedure.
Thanks,
Venkat.
