HA Cluster - Clean Reboot of one node caused disconect
Posted: Fri Dec 20, 2013 12:37 am
Hello:
While performing maintenance on our HA Cluster, we rebooted one of the 2 nodes. Historically this has been handed gracefully. This time BOTH hosts sent logout messages to the initiators and it was 6 minutes! until the initiators could log back in again. This affected some (possibly all) HA LUNs in the cluster.
Where do I start looking for cause and how to prevent in the future?
Additional info:
The change necessitating the reboot was an upgrade to the driver for the RAID controller.
Starwind Host OS: Windows 2008 R2 SP1
Initiator OS: Seen from both Windows 2008 R2 SP1 ad Windows 2003 R2 SP2.
Starwind Version: v6.0.0 (Build 20120927, [SwSAN], Win64)
Thank you for any assistance you can provide to avoid this in the future.
