Task 4: Recover the NetWorker Server Bootstrap
In this task, you will recover the bootstrap save set. Recovering the bootstrap
overwrites the media database in the <NetWorker_install_path>\mm directory
and recovers the resource configuration files to a temporary directory named
<NetWorker_install_path>\res.R.
Note: The mmrecov command is used to recover only the media database and
resource configuration files. To recover the client file indexes (including the
NetWorker server’s own client file index) use the nsrck command. For details
about the mmrecov and nsrck commands, refer to the Legato Command
Reference Guide.
To recover the bootstrap save set:
1. Load the backup or clone volumes that contain the most recent bootstrap
save set. If you ran the scanner command in the previous task, you have
already completed this step; proceed to step 2.
If you did not run the scanner command in the previous task, do the
following:
a. Insert into the storage device the backup or clone volumes that
contain the most recent bootstrap save set. (Do not use the
NetWorker software to mount the volume; the NetWorker server
does not currently have the necessary information to recognize the
media.)
b. If you are using an autochanger, run the following command to load
the first volume of the bootstrap save set into the first drive of the
autochanger:
nsrjb -lnv -S # -f device_name
where:
– # is the slot where the first volume is located
– device_name is the pathname for the first drive
Note: You can obtain the device_name using the inquire command.
2. To recover the NetWorker server’s bootstrap, run the following command:
mmrecov
3. If you are using clone volumes and have not loaded all of the necessary
volumes, mmrecov prompts you for the original volume. In that case:
a. Enter [Ctrl]+[c] to exit mmrecov.
b. Delete the records of the original volumes by running the following
command:
