You're on the right track - the drive is in owned by TSM  so AIX can't use it.
I remember having this problem when we first set up ADSM ver 2. We are able to
run run the mksysb with TSM server software down - have you tried that? It's
been a long time since we played with this, but I'm guessing that to access the
drive from AIX while TSM is up you may need to put the drive offline using
UPDATE DRIVE ONLINE=NO then go into smit/devices/ADSM devices and remove the
drive.

 Subject: MKSYSB Failure After TSM Install







All,

I ran the command mksysb -i -X /dev/rmt0 and received
the following messages:

Creating information file (/image.data) for rootvg.....
Creating tape boot image./dev/rmt0.1: There is a request
to a device or address that does not exist.
0512-044 mksysb: Cannot access device /dev/rmt0.1.
tctl retension failed with return code 2.

The box is a 4.3.3 7248-43P with an external IBM
7206-005 DDS-2 4GB tape drive.  And yes I have verified
that the special files rmt0 and rmt0.1 are present
in the dev dir.

This is a brand new machine EXCEPT that it has a 3.7.2.0
TSM server on it and I am also using the same tape drive
for local TSM backups.  So in order to use the 4mm tape
drive I had to go into smit and define a TSM tape drive on
top of the rmt drive.  Of course I have already tried
deleting the entire TSM drive including the special files
to no avail.  And I have even delete all the definitions
ran cfgmgr and also rebooted, but nothing seems to allow
me to get a good mksysb.

Any ideas?
