We have noticed our 2012 -r2 Hyper-V hosts showing plenty of below CSV paused state error in the system event log during backup window
System Error 5120: Cluster Shared Volume "CSV Name" has entered a paused state because of '(c00000b5)'. All I/O will temporarily be queued until a path to the volume is reestablished.
The above error noticed most of CSVs and only happening during when backup jobs are running
We use Veeam B&R 9 Patch 1, 2012-r2 Hyper-V and EqualLogic PS6110 and HITKIT(V-4.8.x) is installed on hosts for HW snapshot.
Any inputs to resolve this issue is highly appreciated
