NetWorker Server Recovery Requirements
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
4NetWorker 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
–# 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:
