I allready tried all that. with 1 drive 3 drives (original) 5 drives etc.
the drives are not the problem, the problem is the medium changer.
(/dev/smc0)

First when you remove drives and don't connect or connect booting gets hung
sometimes to autodetect .It should come up sometimes after 20min. This is my
experience.
Please use same no: of drives that  were there as before.
If this does not work then!!!!
First delete using smitty or rmdev  tape drive .Then run cfgmgr.Now once
again connect drive with same no: as there were before.

Now you need to Add TSM tape drives with smitty .See for proper connection
nos.You should  be ok now.

lsdev -Cc tape o/p should show as available.

Try this it should work.

If adsm does not init library it also shows that ur library is damaged.
But before proceeding further see that u bring up all tape drives as
available and not defined.

Hi all,

This morning I've changed a broken tapeunit (3570-C1A) in the library
(3575L32) and while I was at it put in an extra 3 drives.
AIX (4.3.2.0) had problems booting, and hung on LED 899.
Solved the problem by attaching the drives one by one on the scsi bus.
Now /dev/smc0 doesnt want to go through cfgmgr smoothly. when unhooking the
cable for a few seconds its being configured anyway. at least according to a
lscfg -Cs scsi.
It says its available. Now adsm (3.1) doesnt want to initilize the library.
I've tried everything. unhooking al drives but 1 (rmt0 or drive1) I've tried
other cabling, terminators and even screwed out the drive and replaced it by
another. 2 AIX guru's have looked at it but they havent got a clue either.

I'm beat, my backups havent been able to migrate, and backups are starting
at 00:00  hour!!!

Ps: richard, sorry for sending directly to u, but I'm really desperate.
