Verify mksysb with "AIX 4.1"

[jriordan]

Hi all,
I have been trying to find out how I can verify a mksysb tape in AIX 4.1. In 5.1 I would use "listvgbackup" and 4.3 I would use the menu in smit. Well, as I have discovered these options do not exist in 4.1. The man page on mksysb in 4.1 says to look at the 4.1 Installation guide to find out how to verify a mksysb tape. Well, I can't seem to find this guide and IBM's website has it but it can't be downloaded it needs to be ordered.

Any help would be greatly appreciated.
Thanks
John

AIX V4:

The mksysb tape has 4 images on it:
---------------------------------------------------------------------------
boot image | install image | empty TOC | system backup image
---------------------------------------------------------------------------

To test the first 3 images, use the following commands. All this does is checks for tape media errors. If you want to be absolutely sure, boot the tape.

# The first 3 images are always written in 512 byte blocks
#
chdev -l rmt0 -a block_size=512
dd if=/dev/rmt0.1 of=/dev/null
dd if=/dev/rmt0.1 of=/dev/null
dd if=/dev/rmt0.1 of=/dev/null

To test the 4th image, use the commands:

# The system backup image is written at whatever block size the
# tape device was set to when the mksysb was made. You might
# assume 512 and skip the commands up through 'chdev' and the
# optional 'ibs' parameter to dd in the subsequent section. If
# you do and the block size is not 512, you'll get an I/O error.
#
tctl rewind
restore -xqvf /dev/rmt0.1 -s2 ./tapeblksz
chdev -l rmt0 -a block_size=$(awk '{ print $1 }' tapeblksz)

dd if=/dev/rmt0 [ibs=$(awk '{ print $1 }' tapeblksz)] | restore -Tqf- >/dev/null


Check TOC:
tctl -f /dev/rmt# rewind
Restore –s4 –Tvqf /dev/rmt#.1 > /tmp/mksysb.log
