Create Notification for Cluster Share Volume Disk Capacity

I am new to System Center Operations Manager but am slowly learning. We are running SCOM 2012 R2 and I want to get notifications when there are issues in our 2012 Hyper-V Cluster, specifically when the free space on our CSVs gets below
100 GBs. I have a notification channel setup and I am receiving notifications on other issues on monitored servers as they occur. I have imported the Cluster, Core OS and Windows Server OS management packs which have enabled me to see in Monitoring
> Microsoft Windows Server > Performance > Cluster Share Volume Disk Capacity the Free Space for the CSVs in a graph, now what do I need to do so I can get a notification when the free space on our CSVs gets below 100 GBs or whatever other
level I want to set it at? Thanks.

Hi WSUAL2,
Have you created a separate Subscription for Disk alerts? Please refer below link for "How to configure notifications".
http://blogs.technet.com/b/kevinholman/archive/2012/04/28/opsmgr-2012-configure-notifications.aspx
In your case, you need to select the respective Cluster Disk monitor while creating new Subscription.
Check mark this --> "Created by specific Rule or Monitor"
Before that make sure that you are getting alert in console. By seeing Alert Details, you can find the correct Rule/Monitor name.

Logical Disk Performance counter for cluster shared volume on Hyper-V

Hello All,
I am trying to collect counters like latency, queuelength from Win32_PerfFormattedData_PerfDisk_LogicalDisk WMI class.
Output of "Name" attribute for logical disks in this class as below:
Name: _Total
Name: C:
Name: E:
Name: HarddiskVolume1
Name: Q:
Name here doesn't show the actual label so I queried Win32_Volume class and wanted to join with performance WMI class. Out put of Win32_Volume is as below:
Caption: E:\
Label: New Volume
Name: E:\
Caption: Q:\
Label: Quorum
Name: Q:\
Caption: C:\
Label: Voume C
Name: C:\
Caption: F:\
Label: SAN
Name: F:\
Please note that "Name" attribute matches for all except one with label "SAN". This is cluster shared volume and "Name" attribute value is "HardDiskVolume1" in Win32_PerfFormattedData_PerfDisk_LogicalDisk class.
Is this is a configuration issue or any other alternative to get volume label and corresponding performance counters.
Thanks in advance
Regards,
Udupa

Hi Udupa,
I haven't found a better way, if you want to combine the two script, please refer to the script below:
$output=@()
$volumes = gwmi Win32_Volume
foreach($volume in $volumes){
$match=($volume.name).TrimEnd("\")
$counter=gwmi Win32_PerfFormattedData_PerfDisk_LogicalDisk |where{$_.name -eq $match}
$Object = New-Object PSObject
$Object | add-member Noteproperty name $volume.name
$Object | add-member Noteproperty label $volume.label
$Object | add-member Noteproperty AvgDiskQueueLength $counter.AvgDiskQueueLength
$output += $Object
$output
I hope this helps.

System creates group for every share point

Every time I create a new share point on my OS X Server 10.5, a group is created by the system on the fly along with it.
For example, I created a folder nameded Research Office and shared in Server Admin. Then when I assign the permission for the share point in Server Admin, I see a group called Research Office group with a GID of 124. However, this group does not appear in Workgroup Manager so I can not assign members to it.
Anyone see this before?

These groups are 'local' (Not LDAP) I still have difficulty wrapping my head around some of the rules about the 'how' this works but assigning LDAP users to this group does work!
OK _To see this group(s)_.
1: Open Workgroup Manager.app.
2: Select /Local/Default in your Authentication list (this spot is between the Toolbar and the 4 (or 5) icons for User, Groups, Computer Groups etc.) We are looking for the place that should say something like 'Authenticated as XXXXX to local directory /Local/Default')
3: Select the Groups icon (3 Shadows standing together)
4: Select Menu View, Show System Users and Groups
5: Now you will be able to select these groups.
_To add LDAP users and groups to this 'local' group._
1: Highlight the group in question
2: Select the Members tab in the right pane
3:Click the plus
4: After the tray slides out, at the top of the tray, you will see a disclosure arrow and Local Directory /Local/Default. Click on it and select /LDAP/127.0.0.1
Now you can select your LDAP users to assign rights.

Creating notification for client layer afterCommit of transaction

I am using JDeveloper 11.1.1.4.0 and I want to create notification in order to display successful message on client side in "afterCommit" method ApplicationModule. I know one way is through adding FacesMessage in FacesContext in bean but is there any way on model side?

Oracle doc says a better way to send notifications upon a successful commit is by declaring a business event. You can check the below link how to create business event.

Can't create constant for cluster with waveform inside it..

I have an indicator cluster that contains a timestamp, string, three booleans, two doubles, and a graph using a 1D array of waveform datatype. When I include the waveform graph inside the cluster, I can't right click the control terminal and create a constant. Is it possible to create a constant for the waveform datatype??
Attachments:
front_panel_cluster_with_waveform_control.ctl ‏24 KB

There is an "Analyze" palette that has numerous analysis functions that operate on 2D arrays. It is located next to the "Waveform" palette.
None of the graphs or charts have constant equivalents, so if you use a 2D graph in the cluster you still can't create a constant for the cluster. Since I not sure what your reason is for using a graph in a cluster, I am making this next comment ignorant of your use case. With that said... In general graphs are very useful for viewing data. They are not recommended for data transferring as they carry a much larger footprint than a waveform datatype or 2D array. If you are frequently using this typedef cluster in your VIs, especially in VIs that are not part of your user interface, you may want to consider not
using a graph in the cluster. Or you could have 2 versions of the cluster -- one for user interface display purposes (with a graph) and one for programming purposes (no graph).

Error when adding a disk to Cluster Shared Volumes

When adding a disk to Cluster Shared Volumes via Failover Cluster Manager, I get a couple of errors.
Event ID 5145 in System Log:
While adding the disk ('Cluster Disk 1') to Cluster Shared Volumes, setting explicit snapshot diff area association for volume ('\\?\Volume{420e2cc4-4fb4-41be-afb1-65f2ee62457a}\') failed with error 'HrError(0x8004230d)'. The only supported software snapshot
diff area association for Cluster Shared Volumes is to self.
Cluster disk resource 'Cluster Disk 1' failed to delete a software snapshot. The diff area on volume '\\?\Volume{420e2cc4-4fb4-41be-afb1-65f2ee62457a}\' could not be dissociated from volume '\\?\Volume{420e2cc4-4fb4-41be-afb1-65f2ee62457a}\'. This
may be caused by active snapshots. Cluster Shared Volumes requires that the software snapshot be located on the same disk.
Any ideas why I'm getting this error? This disk was previously added as a CSV to different Windows failover cluster, if that matters. Thanks.

Hi,
As the disk was previously used as a CSV, I assume there is still data on it.
Please check if any VSS snapshot created on that disk. If so, delete them and re-add it as a CSV to see the result - a quick way is to backup important files and perform a re-format if you cannot confirm.
If you have any feedback on our support, please send to [email protected]

Unable to create a notification for a group (Cisco Unity Express 3.2)

There is Cisco ISR 2821 with CME 7.1 and Cisco Unity Express 3.2.
I am trying to create notifications for a group named AAA in CUE.
I do following (GUI):
1. Go to Configure -> Groups
2. Click on the group name AAA.
3. In Group Profile window 'Enable notification for this user/group' option is enabled.
4. Go to Mailbox tab. There is an associated mailbox with ticks against Enabled and Fax Enabled.
5. Go to Notification tab and see the warning:
No Notification Devices found for User/Group
Also, there are another several groups on this system and I am able to turn notification on for them. These groups have the same owners and members that AAA has. Moreover, if I create a new group and set it up absolutely the same as AAA, I can turn notifications on for it.
The problem in this way is that we have our custom greetings and after I created a new group, for example BBB, with the same settings (as AAA, inluding Primary Extansion and Primary E.164 Number) and remove these numbers from AAA, then it works and users would receive notification about new voice messages. BUT, when I call BBB I listen to standart Cisco greeting promts.
I don't undestand why it happens, because all these greetings are determined in Voicemail -> Auto Attendant section and I did not any changes here at all.
How can I fix this 'notification' problem?
Thanks.

Process with success:
unzip the packet in: C:\APEX
1. Install:

Hyper V hosts with Cluster Shared Volume do not provide Shared VHDX ability

Hi there, i've configured a pair of Hyper V hosts (UCS B230 M2) with SAN-Boot and access to a Shared Fiber Channel LUN.
No matter what I try, when I add a SCSI Adapter and one VHDX virtual disk to a VM, the option for "Advanced" never shows up therefore I can not share the VHDX file between another VM, which prevents any VM based clustering from working (IE: Clustered
SQL server)
Here are the settings I have configured:
The LUN has been formatted with NTFS
The Hyper V hosts have been configured as a Windows Cluster with an IP address and the Fiber Channel LUN configured as a Cluster Shared Volume
I follows the guides below
Create a CSV
https://technet.microsoft.com/en-us/library/dn265980.aspx
Create a shared VHDX
https://technet.microsoft.com/en-us/library/dn282283.aspx
Further details:
Two HyperV server core hosts built
Both joined to AD
Both joined to a Windows failover cluster
One 2TB Fibre Channel LUN presented from an EMC VNX array to both hosts
LUN formatted as NTFS
LUN created as a Cluster Shared Volume
Cluster Shared Volume present on both HyperV hosts
VM created within the Cluster Shared Volume
VM Booted up and Windows 2012 has been installed
VM gracefully shut down
Through the HyperV Manager, going in to VM settings,create a SCSI adapter, create a new VHDX file inside the CSV, the “Advanced” option for the VHDX is not present, therefore the option to make the VHDX file shared is not available
I have followed all steps in the Microsft Technet pages to create a CSV and a VM with Shared VHDX
I’ve cleared all settings and restarted multiple times, but this option is not present

Hi Sir,
>>No matter what I try, when I add a SCSI Adapter and one VHDX virtual disk to a VM, the option for "Advanced" never shows up therefore I can not share the VHDX file between another VM
>>Yes we are using Hyper-V Server 2012 R2
As we know Hyper-v server 2012R2 is a free version without GUI , I'm afraid you are not using Win 8.1 or other windows server 2012R2 to manage that free version hyper-v server .
Shared vhdx is a new feature came with 2012R2 , if use previous windows to manage 2012R2 you will not see "advanced" option (The blue circle belongs 2012 , the red circle belongs to 2012R2 ):

Create Notification Navigation Button not working in Order Objects Tab

Hi Gurus,
I am having an issue in Order --> Objects tab. I want to create notification for additional technical objects for the order. When I enter the technical object details and press enter, a "Create Notification" navigation button gets activated for that line item. But when I press that button, nothing happens. On the other hand if a select multiple line items and then press "Create Notification" button at the bottom of the line items, I am able to create notifications for the selected line items.
Can someone help me suggest what can be the problem or suggest a Note which might restore the functionality of the "Create Notification" navigation button at the line item level.
Thanks in advance for the help.
Best Regards
Vikas Hali

Vishal,
I dont think the Notification Create Button from line item is pretty much dependent on the Customization Settings or any sap note concerning this has not been as yet brought into my notice. In my system, this is working appropriately. The problem with this which i can think of is either an authorization issue or you should raise an oss for this.

Notification for Refurbishment order

HI ALL,
I would like to know whether we can create Notification for Refurbishment order. As per my understanding we can not create the Notification for Refurbishment order. But after reading the document given in URL I have confused.
http://help.sap.com/saphelp_erp60_sp/helpdata/EN/4e/01e93a2876a81ae10000000a11402f/content.htm
Kindly let me the procedure and configuration setting for creating the Notification for Refurbishment order.

Ramu,
If its your business requirement is like to link Notification to Refurbishment order , You can very well attached it in object list of Refurbishment order.

Notifications for objects in the objectlist

Hi,
I am trying to develop a webdynpro application to imitate IW32 transaction in SAP ( albeit it will be much simpler to use with majority of func. on single screen ). I am able to create notifications for the work order object list using 'BAPI_ALM_NOTIF_CREATE' and assign this notification to the objects in workorder objectlist using 'BAPI_ALM_ORDER_MAINTAIN' however when i open up the object notification in IW23 transaction the notification has a OSNO (outstanding notif) system status and no work order number displayed. ( so you can see the notification nr in work order objectlist via IW32 txn and on double click you go the notificaiton , however navigation the other way round is not possible as no work order nr is displayed in notification).
However if i try the same thing via IW32 transaction the new notification created has NOPR ORAS( notif in processing, order assigned ) system status with the workorder number displayed in notification . ( + I want same behavious when i create notif thorough web dynpro + ).
I have tried using the 'STATUS_UPDATE' Fm to update status of newly created notifications and it seems to change notification status from OSNO to NOPR ORAS but still the workorder number does not show up ( so it defeats the whole purpose of system status change ).
Please let me know if anyone else has faced a similar issue before and how this can be handled.
Thanks,
Vivek Priyadarshi
Edited by: Vivek Priyadarshi on Feb 10, 2011 9:31 PM

issue resolved by implementing an enhancement in LIQS0F08. The variable sfbcall-aufnr in form check_status_to_order has to be set with order nr. AUFNR. This variable is set through IW32 transaction however somehow it does not get set when creating notifications through 'BAPI_ALM_NOTIF_CREATE'.

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)
  - Writer Failure code: 0x800423f0 (<Unknown error code>)

  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.
Source: VolSnap, Event ID 27, The shadow copies of volume x were aborted during detection because a critical control file could not be opened.
I only have one instance of each of these and both of the below are from HST3
Source: VSS, Event ID 12293, Volume Shadow Copy Service error: Error calling a routine on a Shadow Copy Provider {b5946137-7b9f-4925-af80-51abd60b20d5}. Routine details RevertToSnashot [hr = 0x80042302, A Volume Shadow Copy Service component encountered an
unexpected error.
Source: VSS, Event ID 8193, Volume Shadow Copy Service error: Unexpected error calling routine GetOverlappedResult. hr = 0x80070057, The parameter is incorrect.
So, basically, everything I have tried has resulted in no success towards solving this problem.
I would appreciate anything assistance that can be provided.

Tim,
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

Cluster Shared Volume disappeared after taking the volume offline for Validation Tests.

Hi,
After an unknown issue with one of our Hyper-V 4 Node cluster running on Server 2008 R2 SP1 with fibre channel NEC D3-10 SAN Storage all our cluster shared volumes were in redirecting mode and I was unable to get them back online. Only after rebooting all
the nodes one by one the disks came back online. Eventlog messages indicated that I had to test my cluster validation. After shutting down all the virtual machines I set all the cluster shared volumes offline and started the complete validation test. The following
warnings/errors appeared during the test.
An error occurred while executing the test.
An error occurred retrieving the

Manager snap-in, you can use the Repair function (in the properties sheet for the disk) to repair the new or restored disk. If the disk will not be replaced, delete the associated disk resource. (Event 1034)
Cluster disk resource found the disk identifier to be stale. This may be expected if a restore operation was just performed or if this cluster uses replicated storage. The DiskSignature or DiskUniqueIds property for the disk resource has been corrected.
(Event 1568)
In disk management the disk is unallocated, unknown, Reserved. When the resource is on one node and i open disk management i get the warning that i have to initialize the disk. I did not do this yet.
Reading from other posts i think that the partition table got corrupted but i have no idea how to get it back. I found the following information but it's not enough for me to go ahead with: Using a tool like TestDisk to rewrite the partition table. then
rewriting the uniqueID to the disk brought everything back. But still no explaination as to why we had our "High Availability" Fail Over cluster down for nearly 2 Days. This happened to us twice within the past week.
Anybody that an idea how to solve this? I think my data is still intact.
Thanx for taking the time to read this.

Hi,
Error information you provided indicate disk connection failure issue, please confirm shared disk 4 is available:
To review hardware, connections, and configuration of a disk in cluster storage:
On each node in the cluster, open Disk Management (which is in Server Manager under Storage) and see if the disk is visible from one of the nodes (it should be visible from one node but not multiple nodes). If it is visible to
a node, continue to the next step. If it is not visible from any node, still in Disk Management on a node, right-click any volume, click Properties, and then click the Hardware tab. Click the listed disks or LUNs to see if all expected disks or LUNs appear.
If they do not, check cables, multi-path software, and the storage device, and correct any issues that are preventing one or more disks or LUNs from appearing. If this corrects the overall problem, skip all the remaining steps and procedures.
Review the event log for any events that indicate problems with the disk. If an event provides information about the disk signature expected by the cluster, save this information and skip to the last step in this procedure.
To open the failover cluster snap-in, click Start, click Administrative Tools, and then click Failover Cluster Management. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and
then click Continue.
In the Failover Cluster Management snap-in, if the cluster you want to manage is not displayed, in the console tree, right-click Failover Cluster Management, click Manage a Cluster, and then select or specify the cluster that
you want.
If the console tree is collapsed, expand the tree under the cluster you want to manage, and then click Storage.
In the center pane, find the disk resource whose configuration you want to check, and record the exact name of the resource for use in a later step.
Click Start, point to All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
Type:
CLUSTER RESOURCE DiskResourceName /PRIV >path\filename.TXT
For DiskResourceName, type the name of the disk resource, and for path\filename, type a path and a new filename of your choosing.
Locate the file you created in the previous step and open it. For a master boot record (MBR) disk, look in the file for DiskSignature. For a GPT disk, look in the file for DiskIdGuid.
Use the software for your storage to determine whether the signature of the disk matches either the DiskSignature or DiskIdGuid for the disk resource. If it does not, use the following procedure to repair the disk configuration.
