If you want use the "$?" or "$status", you can do this :
mt -t /dev/rmt/0m rewind
if [ $? -ne 0 ]; then
   echo "Backup error"
   exit 1

mt -t /dev/rmt/0m rewind
if ( $status != 0 ) then
   echo "Backup error"
   exit 1

In this case, you donīt need that your tape is on the driver.

I hope help you !

READ_TAPE(8)						       AFS Command Reference						      READ_TAPE(8)

read_tape - Reads volume dumps from a backup tape to a file SYNOPSIS
read_tape -tape <tape device> -restore <# of volumes to restore> -skip <# of volumes to skip> -file <filename> [-scan] [-noask] [-label] [-vheaders] [-verbose] [-help] DESCRIPTION
read_tape reads an OpenAFS backup tape and prompts for each dump file to save. This command does not require any OpenAFS infrastructure. This command does not need an OpenAFS client or server to be available, which is not the case with the backup(8) command. The dump files will be named for the Read/Write name of the volume restored. After saving each dump file, vos restore or restorevol can be used to restore the volume into AFS and non-AFS space respectively. read_tape reads the tape while skipping the specified number of volumes. After that, it restores the specified number of volumes. read_tape doesn't rewind the tape so that it may be used multiple times in succession. OPTIONS
-tape <tape device> Specifies the tape device from which to restore. -restore <# of volumes to restore> Specifies the number of volumes to restore from tape. -skip <# of volumes to skip> Specifies the number of volumes to skip before starting the restore. -file <filename> Specifies an alternate name for the restored volume dump file rather than the default of the volume name. -scan Scans the tape. -noask Doesn't prompt for each volume. -label Displays the full dump label. -vheaders Displays the full volume headers. -verbose Produces on the standard output stream a detailed trace of the command's execution. If this argument is omitted, only warnings and error messages appear. -help Prints the online help for this command. All other valid options are ignored. EXAMPLES
The following command will read the third through fifth volumes from the tape device /dev/tape without prompting: % read_tape -tape /dev/tape -skip 2 -restore 3 -noask PRIVILEGE REQUIRED
The issuer must have access to read and write to the specified tape device. SEE ALSO
