We are using Commvault Intellisnap (Thin Image CCI) on a G400. Occasionally we have backup failures with error: HORCM command failed. : [Failed to lock resource group] due to raidcom error EX_EACCES being returned by the array. The Command Control Interface User guide says this error code indicates "The resource that you specified to lock or unlock has already been used by another user." What's not clear to me is who is this other user. These backups take place well into the night, so I'm inclined to think the other "user" is some automated system maintenance on the array. What logs would I have to check to verify that? Also, is there a way to stop the maintenance from happening during a specific window to prevent the resource contention? Is there anything that can be done to prevent the resource contention?
Any help would be greatly appreciated. Thanks!
