Hi friends,

i have an great procedure for you.

1. insert tape into tape drive rmt#

2. Determinate block size and set extended file marks to YES

1. OLD_BS=$(lsattr El rmt# -a block_size F value)
2. chdev -l rmt# -a extfm=yes
3. tctl f /dev/rmt# rewind
4. chdev l rmt# -a block_size=512
5. tctl f /dev/rmt# rewind

3.Create BosBoot-Image on tape

1. bosboot d /dev/rmt#.1 a

4.Create mkinsttape block on tape (list of min. BOS files)

1. mkinsttape /dev/rmt#.1

5.Create mksysb marker on tape

1. echo Dummy tape TOC | dd of=/dev/rmt#.1 bs=512 conv=sync

6.Change block size to OLD_BS

1. chdev l rmt# -a block_size=${OLD_BS}
2. tctl f /dev/rmt# rewind
3. tctl f /dev/rmt#.1 fsf 3

7.Write mksysb file to tape

1. dd if=/dir/mksysb.file of=/dev/rmt#.1 ibs=512 obs=${OLD_BS}

Now, you have an mksysb tape for recovery or cloning.

Hi,

(let me revive this old thread...)

I like the procedure mentioned here, but have two questions:

I want to convert sysbackup file to tape on different server. Does it matter? And would be different AIX versions a problem?

Especially in relation to the step "Create BosBoot-Image on tape" - it seems to me that it builds that image from local system...

Second question: how can I verify correctnes of such newly created tape? I know there is option "Verify the Readability of a Backup (Tape only)" in smith but does it check just readability or it guarantees that the tape is OK from all aspects?

Thanks

Tibor
