Clustered Cell Manager requires omnirc parameter

HP Data Protector

I just stumbled across an issue introduced with Data Protector A.08.00 and the new PostgreSQL database on clustered Cell Managers running on Linux and HP-UX.

It allows a much more granular recovery than in previous versions, since it’s done using a fully featured module instead of a file system hot-backup.
