HP XP P9000 Replication Manager Software 7.6.1-00 Configuration Guide

After a VSS backup, a disk containing a backup server's secondary volume is taken offline. However,
if the backup fails, the disk might be put online. In such a case, follow the procedure described in
“Disk status remains online after replica operation is complete” on page 141.
Host Bus Adapter (HBA)
Make sure that both the HBA and HBA driver support VSS. Application Agent does not support Emulex
Full Port drivers.
When using a VSS Provider not bundled with Application Agent
Beginning with 7.1, the VSS Provider bundled with Application Agent is named P9000 RM Shadow
Copy. When Application Agent is upgraded, the VSS Provider is automatically upgraded as well.
However, if the currently installed VSS Provider was not originally bundled with Application Agent,
you must remove it manually and use Application Agent to install P9000 RM Shadow Copy.
