Recovering Volume Sets
3
Important: Do not append _VOLUME_SET to the end of an MPE system volume set.
When an HP system is installed, it automatically creates the MPE system volume,
MPEXL_SYSTEM_VOLUME_SET.
The name of the directory accounting information file for an MPE volume set is the
same as the name of the MPE volume set for previously saved data. The new name has
an extra tag, _DAF. Therefore, if you enter the name of or mark an MPE volume set
during the recovery process, you recover the directory accounting information file only.
You can recover an entire MPE volume set by using the save set-based recovery
method, which uses the save set recovery identification (ssid) for the MPE volume set.
When NetWorker saves an MPE volume set, it saves the file directory accounting
information in the file
/PROJECTS_VOLUME_SET_DAF. Using the example above,
when you recover this specific file, it will contain only the file directory accounting
information. To recover all the files and directories on an MPE volume set, you use the
save set identification (ssid) for the volume set.
Non-interactive Recovery of a Directory Accounting Information File
Use the non-interactive recovery method to recover the directory accounting
information file of an MPE volume set.
With a non-interactive recovery you do not browse the save sets or mark the files for
recovery. Enter the NSRRECOV command and the parameters for the file path of the
MPE volume set for which you want to recover the directory accounting information
file. Perform non-interactive recoveries when you want to recover the directory
accounting information file for an MPE volume set quickly.
To perform a non-interactive recovery of the directory accounting information file only,
enter the NSRRECOV command at the CI prompt:
:
RUN NSRRECOV;INFO="-s jupiter -a /PROJECTS_VOLUME_SET_DAF "
Interactive Browse Recovery of Directory Accounting Information File
Although you can recover an entire MPE volume set using the interactive browse
recovery method, Legato recommends that you use the save set recovery method
instead. Use the interactive browse recovery method to recover the directory
accounting information file only.
The interactive browse process for recovering the directory accounting information file
for an MPE volume set is the same procedure that you follow for recovering files,
groups of files, or directories. Once you have started the NSRRECOV program, as with
files, you can browse the save sets for available recovery MPE volume sets.
Important: You can only restore one directory accounting information file at a time.
