VMWare lost connectivity to storage device during failover
When we do a failover VMWare lost the connection and gives the following error:
Stateless event alarm
Alarm Definition:
([Event alarm expression: Lost Storage Connectivity] OR [Event alarm expression: Lost Storage Path Redundancy] OR [Event alarm expression: Degraded Storage Path Redundancy])
Event details:
Lost connectivity to storage device eui.64327556714b7666. Path vmhba38:C0:T2:L1 is down. Affecteddatastores: Unknown.
When we do a rescan for datastores, it hangs. We can only fix it to reboot the "slave node". (we are running active/passive)
When it's going to reboot, everything is comming back online, but a lot of servers has at that moment corrupt data.
When we failover back to the other side, same problem, and fixed after rebooting the "slave node".
