Symptoms

LUN expansion performed with XtremIO. Microsoft Failover cluster resources fail or go offline during a volume expansion on XtremIO array and before completing the expansion on the host side.Microsoft cluster control holds SCSI reservation but goes offline. XtremIO receives SCSI reservation release later, and immediately acknowledges release once it is received. Communication errors are seen causing the node to be removed from the cluster after seeing the LUNs being expanded.Operating System Version:Windows Server 2012 StandardDell EMC PowerPath Version 6.1 (build 295).All paths are active and alive with no errors.

Cause

An intermittent issue in PowerPath 6.1 code is causing this issue. A change in the Persistent Reservation IN (PRI) load balancing is leading to cluster disk failure during the LUN expansion.

Resolution

To resolve this issue upgrade to PowerPath 6.3 or above. PowerPath for Windows can be downloaded from the following web link: https://support.emc.com/products/1781 Workaround:If upgrading is not possible, you can reduce the occurrence of the issue by performing a LUN expansion with active paths that are reduced to half the HBAs. There is still a risk. Run 'powermt display bus' from the command prompt. That shows the HBA# and target relationship.Run 'powermt set mode=standby hba= dev=' command. This command allows to only send half the paths with I/O to a specific device thereby leaving one initiator HBA active and the other in standby mode assuming only two x HBAs in use.Expand the LUN as planned.Run 'powermt set mode=active hba= dev=' command to restore default state.
