Operating Systems SCO CPIO listing from tape question... Post 302645873 by hicksd8 on Thursday 24th of May 2012 08:27:07 AM

Well it's been a few years since I was deep into SCO Unix but here are my thoughts on this.

FIRSTLY, write protect your cartridge, DAT or whatever to avoid any accidents!!!

As Methyl comments do you have the script/utility that wrote the tape? Many utilities did their own thing and created "headers" and stuff on the front of tapes.

I seem to remember that on SCO

Code:
 
cpio -ivt < /dev/rct0

did not behave the same as

Code:
 
cpio -ivt -I /dev/rct0

Crazy but I think that's true.

Basically, you are right that the switches -ivt should list the tape. The tape might have been written using the -c switch and/or the -B switch but I also seem to remember that cpio could figure that out for itself on a restore.

As Methyl suggests try a no-rewind device several times over and see what happens.

I suggest that you try all these:-

Code:
 
cpio -ivt -I /dev/rct0
cpio -ivt -I /dev/nrct0  (repeat this command several times)
cpio -ivtcB -I /dev/rct0
cpio -ivtcB -I /dev/nrct0  (repeated several times)

You are sure that the tape isn't tar format???

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.
