Indicateurs cluster redondants
Bonjour,
J'ai 95 indicateurs LED circulaire de type booléen dans un cluster en face avant.
J'ai créé mes led, une par une, de sorte que leur étiquette soit différente, de "Booléen 1" à Booléen 95".
J'ai réalisé un chenillard, dont je suis sûr du bon fonctionnement. (voir le VI que j'avais donné dans le forum pour une autre question: ici)
J'ai juste ajouté la fonction "tableau en cluster" avant mon 'indicateurs-cluster' composé de 95 booléens, pour visualiser l'état de mes sorties.
Cependant, je n'ai pas trouvé de moyen sur le diagramme ou à partir de la boite cluster de vérifier dans quel ordre sont rangés mes booléens.
Je n'arrive pas à avoir le détail du cluster.
Cela ne me poserait pas de problèmes si les led s'allumaient dans l'ordre de Booléen 1 à Booléen 95, mais ce n'est pas le cas.
Certaines de mes led s'allument même plusieurs fois.
J'espère avoir été suffisament clair, et que vous pourrez m'indiquer comment obtenir le détail de mon cluster, ou une autre procédure.
Résolu !

Bonjour,
Pour savoir dans quel ordre sont rangés les commandes :
Clique droit sur le cadre du cluster » Ordonner les commandes dans le cluster.
Le redimensionnement automatique peut aussi etre utile...

Bonjour à tous,
Petite question de débutant (que je suis)
J'aborde la question de la gestion des erreurs
Je me rends compte qu'il s'agit d'une chose importante.
Je ne me rends pas bien compte de ce qu'est une "erreur" et quand elle peut se produire.
J'ai pas mal de doc ... mais il me manque une chose ... des exemples de VI générant une erreur.
Rien de tel qu'un exemple que l'on peut analyser, modifier, retourner dans tous les sens.
Et sans quelques exemples, l'idée reste abstraite.
Un de vous pourrait-il, s'il vous plaît, me passer 1 ou 2 exemples de code simple générant une erreur.
par exemple, un boucle while ou For, avec un code minimum générant une erreur.
Que je puisse "voir" et "toucher" la chose !
Merci à tous,
Résolu !
Accéder à la solution.Bonjour Ouadji,
Sous labview une erreur est représentée par un cluster de 3 éléments :
un booléen : il indique si une erreur est générée (true) ou non (false)
un entier numérique : il indique un code d'erreur si on est en présence d'une erreur
une chaine de caractères : elle propose une déscription de l'erreur générée
Vous pouvez donc générer votre propre erreur si vous le souhaitez.
Il est en effet possible de créer une constante "cluster d'erreur", à vous de manipuler cette constante comme bon vous semble pour générer votre erreur.
Voici un petit vi générant une erreur. Ne sachant pas exactement quel type d'erreur vous souhaitez obtenir pour vous analyses j'ai fait un programme d'E/S sur fichier très simple, avec une boucle While.
l'erreur est due au fait que le fichier désigné "fail.ex" est introuvable.
En cablant un indiquateur "cluster d'erreur" au flux d'erreur vous aurez plus de détails sur les valeurs des différents éléments du cluster.
En éspérant vous avoir aidé !
Cordialement,

How do I add indication to a cluster
I have a couple of radio buttons in a cluster and I'd like to add indication to the individual buttons within the cluster. How is this done?
Disregard this post,I figured out how to do it in the help section.

Unable to create cluster, hangs on forming cluster
Hi all,
I am trying to create a 2 node cluster on two x64 Windows Server 2008 Enterprise edition servers. I am running the setup from the failover cluster MMC and it seems to run ok right up to the point where the snap-in says creating cluster. Then it seems to hang on "forming cluster" and a message pops up saying "The operation is taking longer than expected". A counter comes up and when it hits 2 minutes the wizard cancels and another message comes up "Unable to sucessfully cleanup".
The validation runs successfully before I start trying to create the cluster. The hardware involved is a HP EVA 6000, two Dell 2950's
I have included the report generated by the create cluster wizard below and the error from the event log on one of the machines (the error is the same on both machines).
Is there anything I can do to give me a better indication of what is happening, so I can resolve this issue or does anyone have any suggestions for me?
Thanks in advance.

I have also since tried creating the cluster with the firewall and no success.
I have tried creating the node from the other cluster and this did not work either
I tried creating a cluster with just a single node and this did create a cluster. I could not join the other node and the network name resource did not come online either. The below is from the event logs.

I am 100% unable to create a Virtual Windows server 2012 failover cluster using two virtual fiber channel adapters to connect to the shared storage.
I've tried using GUI and powershell, I've tried adding all available storage, or not adding it, I've tried renaming the server and changing all the IP addresses....
To reproduce:
1. Create two identical Server 2012 virtual machines
(My Config: 4 CPU's, 4gb-8gb dynamic memory, 40gb HDD, two network cards (one for private, one for mgmt), two fiber cards to connect one to each vsan.)
2. Update both VM's to current windows updates
3. Add Failover Clustering role, Reboot, and try to create cluster.
Cluster passed all validation tests perfectly, but then it gets to "forming cluster" and times out =/
Any assistance would be greatly appreciate. -
Saving cluster of different data types to a file
Hi,
I use LV 8.6 SDK. I need to save clusters of different data types to a file on a disk, row by row.
To be specific: I have a program that performs various investigations on a signal collected by DAQmx. Each time the quality of the signal is not in a specified boundaries, i get an indication. It is a cluster of time stamp, string, dbl, and Boolean. The program is supposed to run for few weeks in a row so there can be a lot of these indications. I expect to have around 200 000 rows a week (Altogether, divided into several groups).
I thought about TDMS but I am not able to save such a cluster. And I would like to save it as tdms cause i could divide the data to different groups. I also thought about data base but that would be the first time i use db and I really do not have time to learn that now.
I know it is possible to change some of the data types to others, ex Boolean to 0-1, but i need a string and a time stamp there.
Can someone advise me which data format should I use? Which one is the best one in this situation?
Thanks in advance
handreIf you do not need to access data from another application (other than Labview) you can just save it as a binary file.
It is the best choice (for me).
I made an example with one cluster. You can replace that with an array of clusters, of that data type.

Multiple Senior Cluster Members?
Hi Guys,
We've had a few nodes kicked out of one of our production clusters all with messages similar to this:

I wasn't aware that there could be multiple senior members. Is this indicative of something bad going on?
Thanks, Paul
PS Metalink is not behaving so I can't raise it there.Hi Jon,
I've done some more digging into the logs for the whole cluster.
Of the five nodes that left the cluster, three have the same reason:

How closely does a paused declaration correlate with a vote for eviction?
The last node which was kicked out had a similar pattern to trulxfw0003-5 above, however it had significantly more paused declaration messages in the minutes preceding eviction.
We have a listener on the Cluster service which detects the local node leaving the cluster and kills itself. Is this a good idea, or is it safer to let Coherence sort itself out?
Thanks, Paul -
Basic problem with creation of HDInsight cluster with sql-server meta db
We have been testing HDInsight capabilities in the last few days since the introduction of 3.2 I can no longer create HDInsight Haddoop cluster from the old portal https://manage.windowsazure.com with the meta data being in external sql-server (the
new portal does not yet support hdinsight) every which way of trying fails with Error and no indication as what the error is, can anyone help
ThanksHi Medz-pigh,
Can you tell me the stage where it fails? I mean did it stuck when providing metadata info on portal or during deployment it hungs? If you can tell more info it will help.
Thanks and Regards

Hyper-V cluster Backup causes virtual machine reboots for common Cluster Shared Volumes members.
I am having a problem where my VMs are rebooting while other VMs that share the same CSV are being backed up. I have provided all the information that I have gather to this point below. If I have missed anything, please let me know.
My HyperV Cluster configuration:
5 Node Cluster running 2008R2 Core DataCenter w/SP1. All updates as released by WSUS that will install on a Core installation
Each Node has 8 NICs configured as follows:
NIC1 - Management/Campus access (26.x VLAN)
NIC2 - iSCSI dedicated (22.x VLAN)
NIC3 - Live Migration (28.x VLAN)
NIC4 - Heartbeat (20.x VLAN)
NIC5 - VSwitch (26.x VLAN)
NIC6 - VSwitch (18.x VLAN)
NIC7 - VSwitch (27.x VLAN)
NIC8 - VSwitch (22.x VLAN)
Following hotfixes additional installed by MS guidance (either while build or when troubleshooting stability issue in Jan 2013)
KB2531907 - Was installed during original building of cluster
KB2705759 - Installed during troubleshooting in early Jan2013
KB2684681 - Installed during troubleshooting in early Jan2013
KB2685891 - Installed during troubleshooting in early Jan2013
KB2639032 - Installed during troubleshooting in early Jan2013
Original cluster build was two hosts with quorum drive. Initial two hosts were HST1 and HST5
Next host added was HST3, then HST6 and finally HST2.
NOTE: HST4 hardware was used in different project and HST6 will eventually become HST4
Validation of cluster comes with warning for following things:
Updates inconsistent across hosts
I have tried to manually install "missing" updates and they were not applicable
Most likely cause is different build times for each machine in cluster
HST1 and HST5 are both the same level because they were built at same time
HST3 was not rebuilt from scratch due to time constraints and it actually goes back to Pre-SP1 and has a larger list of updates that others are lacking and hence the inconsistency
HST6 was built from scratch but has more updates missing than 1 or 5 (10 missing instead of 7)
HST2 was most recently built and it has the most missing updates (15)
Storage - List Potential Cluster Disks
It says there are Persistent Reservations on all 14 of my CSV volumes and thinks they are from another cluster.
They are removed from the validation set for this reason. These iSCSI volumes/disks were all created new for
this cluster and have never been a part of any other cluster.
When I run the Cluster Validation wizard, I get a slew of Event ID 5120 from FailoverClustering. Wording of error:
Cluster Shared Volume 'Volume12' ('Cluster Disk 13') is no longer available on this node because of
'STATUS_MEDIA_WRITE_PROTECTED(c00000a2)'. All I/O will temporarily be queued until a path to the
volume is reestablished.
Under Storage and Cluster Shared VOlumes in Failover Cluster Manager, all disks show online and there is no negative effect of the errors.
Cluster Shared Volumes
We have 14 CSVs that are all iSCSI attached to all 5 hosts. They are housed on an HP P4500G2 (LeftHand) SAN.
I have limited the number of VMs to no more than 7 per CSV as per best practices documentation from HP/Lefthand
VMs in each CSV are spread out amonst all 5 hosts (as you would expect)
Backup software we use is BackupChain from BackupChain.com.
Problem we are having:
When backup kicks off for a VM, all VMs on same CSV reboot without warning. This normally happens within seconds of the backup starting
What have to done to troubleshoot this:
We have tried rebalancing our backups
Originally, I had backup jobs scheduled to kick off on Friday or Saturday evening after 9pm
2 or 3 hosts would be backing up VMs (Serially; one VM per host at a time) each night.
I changed my backup scheduled so that of my 90 VMs, only one per CSV is backing up at the same time
I mapped out my Hosts and CSVs and scheduled my backups to run on week nights where each night, there
is only one VM backed up per CSV. All VMs can be backed up over 5 nights (there are some VMs that don't
get backed up). I also staggered the start times for each Host so that only one Host would be starting
in the same timeframe. There was some overlap for Hosts that had backups that ran longer than 1 hour.
Testing this new schedule did not fix my problem. It only made it more clear. As each backup timeframe
started, whichever CSV the first VM to start was on would have all of their VMs reboot and come back up.
I then thought maybe I was overloading the network still so I decided to disable all of the scheduled backup
and run it manually. Kicking off a backup on a single VM, in most cases, will cause the reboot of common
CSV members.
Ok, maybe there is something wrong with my backup software.
Downloaded a Demo of Veeam and installed it onto my cluster.
Did a test backup of one VM and I had not problems.
Did a test backup of a second VM and I had the same problem. All VMs on same CSV rebooted
Ok, it is not my backup software. Apparently it is VSS. I have looked through various websites. The best troubleshooting
site I have found for VSS in one place it on BackupChain.com (http://backupchain.com/hyper-v-backup/Troubleshooting.html)
I have tested almost every process on there list and I will lay out results below:
1. I have rebooted HST6 and problems still persist
2. When I run VSSADMIN delete shadows /all, I have no shadows to delete on any of my 5 nodes
When I run VSSADMIN list writers, I have no error messages on any writers on any node...
3. When I check the listed registry key, I only have the build in MS VSS writer listed (I am using software VSS)
4. When I run VSSADMIN Resize ShadowStorge command, there is no shadow storage on any node
5. I have completed the registration and service cycling on HST6 as laid out here and most of the stuff "errors"
Only a few of the DLL's actually register.
6. HyperV Integration Services were reconciled when I worked with MS in early January and I have no indication of
further issue here.
7. I did not complete the step to delete the Subscriptions because, again, I have no error messages when I list writers
8. I removed the Veeam software that I had installed to test (it hadn't added any VSS Writer anyway though)
9. I can't realistically uninstall my HyperV and test VSS
10. Already have latest SPs and Updates
11. This is part of step 5 so I already did this. This seems to be a rehash of various other stratgies
I have used the VSS Troubleshooter that is part of BackupChain (Ctrl-T) and I get the following error:
ERROR: Selected writer 'Microsoft Hyper-V VSS Writer' is in failed state!
- Status: 8 (VSS_WS_FAILED_AT_PREPARE_SNAPSHOT)

- Instance ID: {d55b6934-1c8d-46ab-a43f-4f997f18dc71}
VSS snapshot creation failed with result: 8000FFFF
VSS errors in event viewer. Below are representative errors I have received from various Nodes of my cluster:
I have various of the below spread out over all hosts except for HST6
Source: VolSnap, Event ID 10, The shadow copy of volume took too long to install
Source: VolSnap, Event ID 16, The shadow copies of volume x were aborted because volume y, which contains shadow copy storage for this shadow copy, wa force dismounted.

Wright FloodTim,
Thanks for the reply. I ran the first two commands and got this:
Name
Role Metric
Cluster Network 1
3 10000
Cluster Network 2 - HeartBeat 1 1300
Cluster Network 3 - iSCSI 0 10100
Cluster Network 4 - LiveMigration 1 1200
When you look at the properties of each network, this is how I have it configured:
Cluster Network 1 - Allow cluster network communications on this network and Allow clients to connect through this network (26.x subnet)
Cluster Network 2 - Allow cluster network communications on this network. New network added while working with Microsoft support last month. (28.x subnet)
Cluster Network 3 - Do not allow cluster network communications on this network. (22.x subnet)
Cluster Network 4 - Allow cluster network communications on this network. Existing but not configured to be used by VMs for Live Migration until MS corrected. (20.x subnet)
Should I modify my metrics further or are the current values sufficient.
I worked with an MS support rep because my cluster (once I added the 5th host) stopped being able to live migrate VMs and I had VMs host jumping on startup. It was a mess for a couple of days. They had me add the Heartbeat network as part of the solution
to my problem. There doesn't seem to be anywhere to configure a network specifically for CSV so I would assume it would use (based on my metrics above) Cluster Network 4 and then Cluster Network 2 for CSV communications and would fail back to the Cluster Network
1 if both 2 and 4 were down/inaccessible.
As to the iSCSI getting a second NIC, I would love to but management wants separation of our VMs by subnet and role and hence why I need the 4 VSwitch NICs. I would have to look at adding an additional quad port NIC to my servers and I would be having to
use half height cards for 2 of my 5 servers for that to work.
But, on that note, it doesn't appear to actually be a bandwidth issue. I can run a backup for a single VM and get nothing on the network card (It caused the reboots before any real data has even started to pass apparently) and still the problem occurs.
As to Backup Chain, I have been working with the vendor and they are telling my the issue is with VSS. They also say they support CSV as well. If you go to this page (http://backupchain.com/Hyper-V-Backup-Software.html)
they say they support CSVs. Their tech support has been very helpful but unfortunately, nothing has fixed the problem.
What is annoying is that every backup doesn't cause a problem. I have a daily backup of one of our machines that runs fine without initiating any additional reboots. But most every other backup job will trigger the VMs on the common CSV to reboot.
I understood about the updates but I had to "prove" it to the MS tech I was on the phone with and hence I brought it up. I understand on the storage as well. Why give a warning for something that is working though... I think that is just a poor indicator
that it doesn't explain that in the report.
At a loss for what else I can do,
Charles J. Palmer -
Excessive (?) cluster delays during shutdown of storage enabled node.
We are experiencing significant delays when shutting down a storage enabled node. At the moment, this is happening in a benchmark environment. If these delays were to occur in production, however, they would push us well outside of our acceptable response times, so we are looking for ways to reduce/eliminate the delays.
Some background:
- We're running in a 'grid' style arrangement with a dedicated cache tier.
- We're running our benchmarks with a vanilla distributed cache -- binary storage, no backups, no operations other than put/get.
- We're allocating a relatively large number of partitions (1973), basing that number on the total potential cluster storage and the '50MB per partition' rule.
- We're using JSW to manage startup/shutdown, calling DefaultCacheServer.main() to start the cache server, and using the shutdown hook (from the operational config) to shutdown the instance.
- We're currently running all of the dedicated cache JVMs on a single machine (that won't be the case in production, of course), with a relatively higher ratio of JVMs to cores --> about 2 to 1.
- We're using a simple benchmarking client that is issuing a combination of puts/gets against the distributed cache. The ids for these puts/gets are randomized (completely synthetic, i know).
- We're currently handling all operations on the distributed service thread (i.e. thread count is zero).
What we see:
- When adding a new node to a cluster under steady load (~50% CPU idle avg) , there is a very slight degradation, but only very slight. There is no apparent pause, and the maximum operation times against the cluster might barely exceed ~100 ms.
- When later removing that node from the cluster (kill the JVM, triggering the coherence supplied shutdown hook), there is an obvious, extended pause. During this time, the maximum operation times against the cluster are as high as 5, 10, or even 15 seconds.
At the beginning of the pause, a client will see this message:
2010-07-13 22:23:53.227/55.738 Oracle Coherence GE 3.5.3/465 <D5> (thread=Cluster, member=10): Member 8 left service Management with senior member 1
During the length of the pause, the cache server logging indicates that primary partitions are being shuffled around.
When the partition shuffle is complete, the clients become immediately responsive, and display these messages:
2010-07-13 22:23:58.935/61.446 Oracle Coherence GE 3.5.3/465 <D5> (thread=Cluster, member=10): Member 8 left service hibL2-distributed with senior member 1

Note that there was almost nothing actually in the entire cluster-wide cache at this point -- maybe 10 MB of data at most.
Any thoughts on how we could eliminate (or nearly eliminate) these pauses on shutdown?Increasing the number of threads associated with the distributed service does not seem to have a noticable effect. I might try it in a larger scale test, just to make sure, but initial indications are not positive.
From the client side, the operations seem hung behind the DistributedCache$BinaryMap.waitForPartitionRedistribution() method. The call stack is listed below.

Hyper-V Failover Cluster virtual guests suddenly reboots
The environment is Server 2012 R2 using dual clusters--a Hyper-V Failover Cluster running guest application virtual machines and a Scale-Out File Server Cluster using Tiered Storage Spaces which are used to supply SMB3 shares
for Quorum and CSV. Has anyone had this problem?Anything relevant in the host or guest event logs? I would also check the cluster event logs to see if there are any indications there as well.
Does the guest go down hard or gracefully reboot?
Need more info.

How to make waaveform chart cmpatible to access cluster of data
I am new to LV.. and the concept of Clusters..
I have one sample program of two channel oscilloscope..
The waveform control is having pink border...but when I am trying to do same thing..my control is coming with orange border..
What property do I need to change to make my waveform control compatible to a access cluster of input signals.The color of a wire/control/indicator is indicative of the data type.
The pink color you are seeing means that your data is in a cluster.
The orange color you see means your control is either double or single precision float.
A cluster of data can be sent to an XY graph, but not a waveform chart/graph.
To use a cluster for an XY graph, you should have a 1D array of X data clustered with a 1D array of Y data.
I'm assuming this is not what your cluster is right now.
You probably have a cluster with both channels of data from your oscilloscope.
Use the 'unbundle' function to extract both arrays of data.
Then build an array of each of the two 1D arrays. Pass this newly created 2D array to a waveform chart, and you should be all set.

Servers in cluster go down : twice with different reasons
Hi All,
Our environment is deployed as a cluster with two servers. The configuration being
WL server 5.1 with SP8 on Solaris. Everything was dandy until the cluster went down
twice in a period of 5 days each time with a different reason. Any help in this regard
is highly appreciated.
Thanks-
vijay
First fall :
The first server in the cluster went down after spitting out the "listen failed"
message a couple of thousand times. Immediately following it the second server shut
down with the same error. I understand that in answer to a similar posting in the
group it was suggested to increase the file descriptor count to 1024 or all the way
upto 4096, but doing so would it solve the problem in total.

Hi All
I'm also having similar problem with them. The server went a few times with the
similar error.
We are using WL 5.1 SP12 with file descriptor set to 4096 in Solaris.
I'm very desperate to find a solution to this.
Thanks in advance.

How come you can't put a Tab in a Cluster?
Hello,
How come you can't put a Tab Control in a Cluster?
It looks like users have been asking this question
for years, and all the way back to LV versions 6.1.
Someday, please, pretty please, NI.
Please. Maybe by version 9.5 of LV?
Kevin.Ben wrote: This idea just weirds me out!
Kevin: Sorry Ben, but think how I must feel.
Ben wrote: I understand the cosmetic and GUI interaction part of it OK. Its the "how would it code?" part that send my head spinning.
Kevin: We don't need to worry about that. We'll let the NI LABview guiruis worry about that. They know how to program for TABs and they know how to program for Clustors. Now they just need to put them together.
Ben wrote: Would the tab control be available via bundle by name and unbundle?
Kevin: Yes. It would simply return the value indicating which page is selected.
Ben wrote: If the cluster was an indicator and the tab value was "page1" would the user be able to select page2?
Kevin: Of course, the block diagram would simply pass the enum indicating which page to display.
Ben wrote: On the block diagram, would there be a relationship between the tab and the elements on each tab?
Kevin: None. Or no more so than the relationship of any element on a panel or front panel.
Ben wrote: On the FP the tab control has a "pages" property and from those we can get an array of refs to the controls on the pages. Would we still be able to that within a cluster.
Kevin: Yes. No Differrence.

Kevin: It is not my intent to abuse any Super Cluster in any way shape or from. In contrast, would help to spread out some clutter from ones front pannels and move the clutter into tabs within a cluster. The beauty of it would be that it would come automatic, and handled by labview.
Ben wrote: There was also until recently, limitations on the size of the type descriptors. Very complex FP's and large clusters would be hit by the problem that the type descriptor need more than the 16 bit allocated.
Kevin: I would never suggest even coming close to putting more that 65535 items in a cluser in any fashion.

Kevin: Yes, somebody from NI might know something about why we can't put a Tab in a Cluster.

I had often been mystified by "Why I could not create a waveform datatype block diagram constant?". While at NI Week and talking to Jeff Kodosky I asked him (thinking that I would get a good under-the-hood explanation of the data type used blah, blah, blah... He said "I'm not sure. It ws probably an over-sight." I noticed that in LV 8, you can now create a waveform data type constant.

Maybe it was an oversite. Maybe we can have Tabs in Clusters in 64bit Lab View 9.

Why virtual interfaces added to ManagementOS not visible to Cluster service?
Hello All,
I"m starting this new thread since the one before is answered by our friend Udo. My problem in short is following. Diagram will be enough to explain what I'm trying to achieve. I've setup this lab to learn Hyper-V clustering with 2 nodes. It is Hyper-V
server 2012. Both nodes have 3x physical NIcs, 1 in each node is dedicated to managing the Node. Rest of the two are used to create a NIC team. Atop of that NIC team, a virtual switch is created with -AllowManagementOS
$False. Next I created and added following virtual interfaces to host partition, and plugged them into virtual switch created atop of teamed interface. These virtual interfaces should serve the purpose of various networks available.
For SAN i'm running a Linux VM which has iSCSI target server and clustering service has no problem with that. All tests pass ok.
The problem is......when those virtual interfaces added to hosts; do not appear as available networks
to cluster service; instead it only shows the management NIC as the available network to leverage.
This is making it difficult to understand how to setup a cluster of 2x Hyper-V Server nodes. Can someone help please?

Shahzad.Shahzad,
I've read this thread a couple of times and I don't think I'm clear on the exact question you're asking.
When the clustering service goes out to look for "Networks", what it does is scan the IP addresses on each node. Every time it finds an IP in a unique subnet, that subnet is listed as a network. It can't see virtual switches and doesn't care about
virtual vs. teamed vs. physical adapters or anything like that. It's just looking at IP addresses. This is why I'm confused when you say, "it won't show virtual interfaces available as networks". "Networks" in this context are IP subnets.
I'm not aware of any context where a singular interface would be treated like a network.
If you've got virtual adapters attached to the management operating system
and have assigned IPs to them, the cluster should have discovered those networks. If you have multiple adapters on the same node using IPs in the same subnet, that network will only appear once and the cluster service will only use
one adapter from that subnet on that node. The one it picked will be visible on the "Network Connections" tab at the bottom of Failover Cluster Manager when you're on the Networks section.

Hello Eric and friends,
Eric, much appreciated about your interest about the issue and yes I agree with you when you said... "When the clustering service goes out to look for "Networks",
what it does is scan the IP addresses on each node. Every time it finds an IP in a unique subnet, that subnet is listed as a network. It can't see virtual switches and doesn't care about virtual vs. teamed vs. physical adapters or anything like that. It's
just looking at IP addresses. This is why I'm confused when you say, "it won't show virtual interfaces available as networks". "Networks" in this context are IP subnets. I'm not aware of any context where a singular interface would be treated
like a network."
By networks I meant to say subnets. Let me explain what I've configured so far:
Node 1 & Node 2 installed with 3x NICs. All 3 NICs/node plugged into same switch.
Node1: 131.107.0.50/24
Node2: 131.107l.0.150/24
A Core Domain controller VM running on Node 1: 131.107.0.200/24
A JUMPBOX (WS 2012 R2 Std.) VM running on Node 1: 131.107.0.100/24
A Linux SAN VM running on Node 2: 10.1.1.100/8
I planed to configured following networks:
(1) Cluster traffic: 10.0.0.50/24 (IP given to virtual interface for Cluster traffic in Node1)
Cluster traffic: 10.0.0.150/24 (IP given to virtual interface for Cluster traffic in Node2)
(2) SAN traffic: 10.1.1.50/8 (IP given to virtual interfce for SAN traffic in Node1)
SAN traffic: 10.1.1.150/8 (IP given to virtual interfce for SAN traffic in Node2)
Note: Cluster service has no problem accessing the SAN VM (10.1.1.100) over this network, it validates SAN settings and comes back OK. This is an indication that virtual interface is
working fine.
(3) Migration traffic: 172.168.0.50/8 (IP given to virtual interfce for
Migration traffic in Node1)
Migration traffic: 172.168.0.150/8 (IP given to virtual interfce for
Migration traffic in Node2)
All these networks (virtual interfaces) are made available through two virtual switches which are configured EXACTLY identical on both Node1/Node2.
Now after finishing the cluster validation steps (which comes all OK), when create cluster wizard starts, it only shows one network; i.e. network of physical Layer 2 switch i.e. 131.107.0.0/24.
I wonder why it won't show IPs of other networks (10.0.0.0/8, 10.1.1.0/8 and 172.168.0.0/8)

Version 9.2.3
Cluster | 2 Nodes
Hi all
i have a mysterious problem when i use a client(UC4) to transfer data between 2 DB's over a application. (every 2 min)
If the App runs on just one ClusterNode everything is fine. But when i tell the client to use the 2 members of the cluster, the batch(managed by UC4) sometimes(up to 10 times a day) get a response from the weblogic -> (nBeanUsed: true).
that's why the batch isn't starting and wait's 2 Min again.
We do so because the batch is not allowed to run parallel at the same time.
To check if the queue is already running, the developer uses the following
boolean beanInUsed = iqueueobserver.isIQueueBeanInUse()
But i can't find anything in the logfiles - even if i configured the logging to Debug.
Any Ideas?Screen: 14.1-inch SXGA+ 1400 x 1050 (do you have a 14.1 inch standard aspect ratio laptop? your speaker location on the machine indicates that it is a 15.4 inch T61, and the 9 cell battery size relative to the machine is also indicative of that)
