Since you are on HPUX 11.00 you can use make_recovery -A (-d /dev/rmt/1m, no need if this is the default tape...) - Av if you sit next to console and want to watch the progress...

>How do I use this tape in case of crash of the operating system? do you know?

You would have to choose at boot to to boot from tape, that is at IPL type sea (search) at choose the sequential device
It will then ask interact? choose n
It will then display something like:
:tape (0/12/0/0.3.00.0.0.;0)INSTALL
...
then you have 10 seconds to interrupt the process otherwise it will reinstall the OS...
Unfortunately its a long time since last time I went through the complete process and you will have to wait till Im at home to look through my notes...

It is a good thing to test your recovery tape already to see if it boots ...
Then you may have to use it to modify filesystem size ( and reinstall after...) for you dont have OnlineJFS... but even you had it, you would need to go through using the tape for / /stand and the swap since they have to be contiguous...

amverify

AMVERIFY(8)						      System Manager's Manual						       AMVERIFY(8)

NAME

       amverify - check an Amanda tape for errors

SYNOPSIS

       amverify config [ slot [ runtapes ] ]

DESCRIPTION

       Amverify  reads	an  Amanda  format  tape  and makes sure each backup image can be processed by amrestore and, if possible, the appropriate
       restore program (e.g. tar).

       Amverify runs amrestore on each file of the tape and pipes the output to a restore program (if available) with an option to create a  cata-
       logue of the backup.  The catalogue itself is discarded.  Only the success or failure of the operation itself is reported.

       If  the	backup image cannot be processed by the restore program, e.g. if it was written on a different operating system, the image is sent
       through dd to /dev/null.  This still determines if the tape is readable, but does not do any internal consistency check on the image.

       If config is set up to use a tape changer, the slot argument may be used to choose the first tape to process.  Otherwise, the current  slot
       is used.

       The runtapes configuration parameter determines how many tapes are processed unless it is specified on the command line.

       See the amanda(8) man page for more details about Amanda.
