HP StorageWorks P9000 Replication Manager Software 7.1 CLI User Guide (TB584-96026, May 2011)

• Temporary directory for Extended Commands and the VDI metafile storage directory are created
by the database server and backup server.
• The secondary volume is not always mounted. It is mounted on the E drive (drive character E:)
only while it is operating.
• The primary volume configured as a pair with the secondary volume to be backed up will not be
backed up until the secondary volume is backed up onto tape.
• The cscript //H:Cscript command is executed from the command prompt and the host
parameters are updated.
Processing flow
The figure below shows the flow of processing during backup of an SQL Server database to tape and
restoration of the backed-up SQL Server database to the primary volume in a multiple server
configuration system.
• When usual operation is in the split state, the copy group is first resynchronized, after which the
data is backed up.
• When usual operation is in the pair status, it is unnecessary to resynchronize the copy group before
backing up the data. After the data is backed up to tape, resynchronize the copy group to restore
data to the initial state.
