Windows 2k12 - 0x8007174b failed to bring cluster disk online

I have 3 node Cluster under File Over Cluster 2012 to support High Availability of Hyper-V. Today I got that it fails to reconnect to the Cluster Disk it show my to 2 cluster disk Offline.

 I tried to bring online them from cluster and from disk management but no success.

The only way to bring it online was restarting the complete solution of my Failover Cluster this mean Failover Manager, Hyper-v Host 1, Hyper-v Host 2 and Hyper-v Host 3.

Have you any idea how to get Fix Root?

Do you have all the latest updates? Please post more details from Event logs and Failover  Cluster manager - cluster logs specific to this failure.

I have seen few updates specific to Windows Server 2012 and Failover cluster.

Refer this wiki page for HyperV specific udpates.

http://social.technet.microsoft.com/wiki/contents/articles/15576.hyper-v-update-list-for-windows-server-2012.aspx

Here is another hotfix recommended for Window 2012 Failover cluster which got released on last month.
http://support.microsoft.com/kb/2784261/en-us

You need to verify the event logs and try to see if the issue can be fixed on this updates. Though its always good to install all the updates, While we are in the middle of an issue- take the right one which is for fixing the specific issue.


Good luck.

Hello

this is the event log

Cluster resource 'Cluster Disk 2' of type 'Physical Disk' in clustered role 'acfe8585-f270-4e18-9df6-c4e570b0bafd' failed.

Based on the failure policies for the resource and role, the cluster service may try to bring the resource online on this node or move the group to another node of the cluster and then restart it.  Check the resource and group state using Failover Cluster Manager or the Get-ClusterResource Windows PowerShell cmdlet.

Hi,

Is this event after the updates?

Please provide the last few  related warnings/errors before 1960 which are related to this failure.
Is this  issue happening only for one volume or all volumes from SAN?

I noticed these events when the cluster disk changes from one cluster host to another


Cluster Shared Volume 'Volume1' ('Cluster Disk 1') is no longer accessible from this cluster node because of error 'ERROR_TIMEOUT(1460)'. Please troubleshoot this node's connectivity to the storage device and network connectivity.

I don't know if this extra information helps or not

Our Hyper-V  Solutions  is running with Dell Equallogic PS6100X with PE4870 Switches that connects the array with the Hyper-V Host Servers.

I restarted PE4870 switch stacked and the solution of Hyper-V with  Dell Equallogic PS6100X  works fro about 15 hours and then it goes down again.

I had to restarted again.

Hi,

Do you have dual path for Server-SAN connectivity?
While this issue happens, do you see the disks on DiskManager ?

To my understanding, this issue looks like a storage issue. Redirected IO happens when a node has connectivity issues with storage. If one node is having a connectivity issue to SAN, still the IO should redirected and nothing should fail.
In your case, the disk is failing and I assume that none of your nodes has connectivity to the disk.
I would suggest you to include the storage vendor here. This may be a connectivity issue towards SAN or FC Switch or even an issue with the storage.

Thanks Shaba and everyone

Seems like we already found the issue here.

We have an setup of Hyper-V Virtual Switch assigned to a Network Card for iSCSI on each Cluster Host and it cause a Double connections from each Host to the SAN one with IP an other connection with IP in blank.

We had to disable every Hyper-V Virtual Switch that Point to a Network Card for iSCSI to bring up again the SAN connections and Cluster Volume Shared.

I will keep this topic open for a couple of days to see how it works

I will keep you updated.

Thanks
