NOTE:
If you have specified WWN which is different from the intended import server in the
storage, VSS Provider imports the secondary VOL to the server having the specified WWN and
the process is completed successfully. Then, an error is not found in the VSS Provider log, and
an error message that the target volume is not recognized is output to the event log by the VSS
service.
In this case, make sure that WWN listed in the “WWN of ESXi” specified option is correct.
WWN listed in the “WWN of ESXi” specified option imports the secondary VOL for all HG
configured in the target storage.
The number of the target backup volume
Depending on the configuration of the backup target and system loading status, pair split
processing time exceeds the VSS prescribed time and which may lead to the backup failure.
If frequent timeout occurs in the pair split processing, reviewing the configuration of the backup
target and system loading status is recommended.
Owner node of virtual machine on shared volume
When backing up virtual machines located in the shared volume (CSV) of the failover cluster of
Windows2012 or later, VSS service error may occur, which may lead to the backup failure.

If this failure occurs frequently, consolidating the owner node of the virtual machine in one node
is recommended.
Confirmation procedure:
1.
Deploy the target cluster from the failover cluster manager and click
Role
.
2.
Check
Owner node
of the virtual machine displayed in the
Role
list.
3.
If owner node is located in multiple nodes, consolidate in one node.
Backup from multiple servers and virtual machines at the same time
When backing up from multiple servers and virtual machines at the same time, waiting time for
obtaining resource of the disk array system or command competition occurs, which may lead to
the backup failure.
In this case, take one of the following actions.
•
Change
Waiting time for resource lock/Waiting time for obtaining the privilege to
Modify
and
The number of VSSHP retries
of the setup file to adjust the waiting time for
obtaining resource and the number of retries of the disk array system. See
•
Review the schedule setting at the requester side to avoid coinciding the time frame between
the startup time of the backup job and the completion of the backup job (arrow shown below).
RAID level
RAID1, RAID5, and RAID6 are supported.
Emulation type
OPEN-V is supported.
