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 -mv
command 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 -S slot -f device_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 -B command 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 -B command 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.
