Chapter 3: UNIX Disaster Recovery

Important: If you routinely move NetWorker backup media to an offsite location for safekeeping, and a subsequent file recover operation generates a mount request, the recover operation waits until an operator mounts the request media. To avoid delays when recovering files, use the mminfo -mvcommand to list the media that is associated with the file you want to recover and to retrieve the media from the offsite storage before starting the recover.

To locate the save set ID of the most recent bootstrap (if you do not already have this information):

1.

Insert the most recent media or clone volumes used for scheduled backups

 

 

into the appropriate device.

2.

At the command line, switch to the directory where the NetWorker

 

binaries and executables are located.

3.If you are using an autochanger, insert the first volume of the bootstrap save set into the first drive of the autochanger using the following command:

nsrjb -lnv-Sslot -fdevice_name where:

–slot is the slot where the first volume is located.

–device_name is the pathname for the first drive. You can obtain the device_name using the inquire command.

4.Use the scanner -Bcommand to determine the save set ID of the most recent bootstrap on the media. For example:

Solaris:

scanner -B /dev/rmt/0hbn Linux:

scanner -B /dev/nst0

If you do not locate the save set ID of the most recent bootstrap on the most recent media, run the scanner -Bcommand on preceding media to locate the save set ID of the most recent bootstrap.

5.Record both the bootstrap save set ID and the volume label from the output.
