I got the "lost access to volume" event in the virtual environment everytime the LUNs have replication using HItachi HUR replication tool. Access to the volumes goes up and down util the replication is stopped.
the scenario is:
3 ESX in cluster. replication using Hitachi HUR replication tool between the production DC and the secondary DC. 2 LUNs are being replicated ony con VM in one LUN and only Data in the other LUN.
the event pups up aroun 2 and a half hours from the start of replication, no matter the time the replication kicks off.
10/14 - replication initiated at first group: 6:26 AM ET, second group: 7:12 AM ET, first event at 9:53 AM ET
10/15- replication initiated at 9 AM ET, first event at 11:36 AM ET
10/20 - replication initiated at 11 AM ET, first event at 1:26 PM ET
10/20 - replication re-initiated at 2:10 PM ET, first event at 4:36 PM ET
On the storage array frame side (USPV) disk access time peaks at the time the event pop up. These peaks are also registered in the VM environment.
So far, we have detected a pattern in the symtoms, but not the causes of this symptoms.
Have any one experienced this? or Does any one have a clue on where to look for the causes of this issue?
we run vmware-support command prior the replication kick off and once the event pops up to collect data.
