Hi Tom,
Ops Manager needs Host Agent installed on the host for communication with the host.
The Host Agent has 2 plugins,
1. FSRM plugin - used for File SRM
2. SAN plugin - used for SAN related operations, including LUN create/expand/delete using SnapDrive
The LUN operations are very much restricted & most probably it might be scrapped as we have more advancements in Provision Manager.
Now for your query, FSRM doesn’t require SnapDrive.
SnapDrive is required only for the SAN related operations.
Regards,
Prasad
