Something like:

mt -f /dev/rmt0n fsf 1


Will fast-forward the tape by one set. Then you could try your tar command again when you get to the appropriate place in the tape.

Make sure you are using the "no-rewind" version of the tape device. See the mt man page for more info.

HTH
I tried the mt command and when I displayed the table of contents, it was information from the first save set again. I also tried to tar -xvf the directory I needed, but again it ran for a few minutes but did not restore anything that I needed from the tape. I need to go 15 save sets into the tape. Does that matter? I don't have man pages available here, what is the "no-rewind" version?

st_san_safe(5)							     OBSOLETED							    st_san_safe(5)

NAME

       st_san_safe - determine whether access to tape device special files without the no-rewind-on-close option is allowed (OBSOLETED)

VALUES

   Failsafe
   Default
   Allowed values
   Recommended values
       or

DESCRIPTION

       Note: this tunable is obsoleted and has been renamed to beginning with release HP-UX 11i v3.

       This  tunable  notifies the tape driver whether it should allow access to device special files without the no-rewind-on-close option.  When
       this tunable is on the tape driver will fail any open on a tape device special file without the no-rewind-on-close option (that is, or with
       a status of

       The  tunable  allows  the  safe	sharing of tape devices in SAN tape backup solution configurations.  The disabling of device special files
       without no-rewind-on-close in a SAN tape backup solution configuration prevents the accidental sending of a rewind command  on  close  from
       HP-UX systems via standard tape commands like which would corrupt a backup in process.

   Who Is Expected to Change This Tunable?
       Anyone.

   Restrictions on Changing
       Changes to this tunable take effect immediately.

   When Should the Tunable Be Turned On?
       This tunable should be turned on if the system is going to be used in a SAN tape backup solution configuration.

   What Are the Side Effects of Turning the Tunable On?
       The  tape  driver  will	fail any open to a tape device special file that does not have the no-rewind-on-close option with a status of This
       behavior prevents the usage of any tape device special file without the no-rewind-on-close option.

   When Should the Tunable Be Turned Off?
       This tunable should be turned off if the system is not part of a SAN tape backup solution configuration or the  system  utilizes  will  not
       function unless it has access to device special files without the no-rewind-on-close option.

   What Are the Side Effects of Turning the Tunable Off?
       A rewind may be issued from this system accidentally on close possibly corrupting a backup being issued from another system on the SAN.

   What Other Tunables Should Be Changed at the Same Time?
       None.

WARNINGS

       All  HP-UX kernel tunable parameters are release specific.  This parameter may be removed or have its meaning changed in future releases of
       HP-UX.

       Installation of optional kernel software, from HP or other vendors, may cause changes to tunable  parameter  values.   After  installation,
       some  tunable  parameters may no longer be at the default or recommended values.  For information about the effects of installation on tun-
       able values, consult the documentation for the kernel software being installed.	For information about optional kernel  software  that  was
       factory installed on your system, see at
