Hi,
We did a firmware upgrade on an HP Blade server that is a part of failover exchange 2007 cluster. After this cluster failover failed with error 1034
Cluster physical disk resource 'Cluster Disk 1' cannot be brought online because the associated disk could not be found. The expected signature of the disk was '29EDDDA1'. If the disk was replaced or restored, in the Failover Cluster Management 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.
Don't know whether it is due to firmware upgrade.
We have Blade server and EMC as storage and all the cluster disks are in EMC.
Thanks in advance.
