Moving a mksysb image from hard disk to tape.
How to move a mksysb image from disk to tape and use it
to restore the system.
*CUSTOMER REP: Pat Morgan
PROBLEM: Customer needs to move a mksysb image from hard disk
to an 8mm 5gb tape.
*ACTION TAKEN: Here is our format for creating the mksysb.
The first image is the bosboot image
>bosboot -ad /dev/rmt0.1
The second image is the mkinsttape image
Then we created the third image that is 512 bytes called dummy.
Determine the blocksize for future reference
>lsattr -El rmt0 -- record the blocksize
Change the blocksize to zero
>chdev -l rmt0 -a block_size=0
Then create a file called dummy that has only the words
'dummy toc' in it on the top line. Save the file.
Copy the file to tape with
>dd if=dummy of=/dev/rmt0.1 bs=512 conv=sync
Change the blocksize back to the size that was recorded with
the above lsattr command
>chdev -l rmt0 -a block_size=\#
The fourth image is the mksysb file from the hard disk.
>dd if=\ of=/dev/rmt0
He verified the data with a restore command
>restore -s4 -Tvqf /dev/rmt0.1
