EqualLogic iSCSI disk errors after lost power

Hi,

We have EqualLogic storage and use iSCSI volumes through Windows native iSCSI Initiator. Yesterday we had power outage for 10 min. After that storage and servers booted successfully, just on some volumes we got disk errors that was fixed with Windows chkdsk. Volume are used by Windows 2012 SQL cluster and databases were corrupted after this issue. We have HIT installed on all nodes. Other servers works fine and iSCSI volumes had no issues just SQL instance clustered disks got corrupted. Any idea how could this happen?

thanks

    Hi, we have Write-back cache mode enabled and battery status on both controllers shows as good. Anyway could it be cache's fault even storage was down for about 10-20 minutes?

    thanks

    Raidset you mean Raid configuration of EqualLogic wouldn't have been brought online and we won't be able to see iSCSI volumes?
