Bern,
thank you for your advice. But I have non IBM DLT drive. The problem is,
that software driver for my HBA does not create standard
SCSI devices (with SCSI target and LUN) in Solaris, so it is not possible
to use TSM device driver, which is AFAIK, driven to use only SCSI devices.

This is part of my messages file:
/pci@4,4000/SUNW,qlc@3/fp@0,0/st@w100000e00221f7f5,0 (st85):
May  7 18:32:53 tsm     <Vendor 'DEC     ' Product 'TZ89     (C) DE'>
May  7 18:32:53 tsm unix: st85 at fp0:
May  7 18:32:53 tsm unix:  name w100000e00221f7f5,0, bus address 1
May  7 18:32:53 tsm unix: st85 is
/pci@4,4000/SUNW,qlc@3/fp@0,0/st@w100000e00221f7f5,0
May  7 18:32:53 tsm unix:
/pci@4,4000/SUNW,qlc@3/fp@0,0/st@w100000e00221f7f5,0 (st85) online

AFAIK TSM device driver for nonIBM devices support only SCSI devices, not
FC devices. Or am I missing something?

Now I am going to change Fcode in HBA so that it will be original Qlogic
2200 and I will use Qlogic device drivers. According to Tivoli
it should be supported configuration.

Hello Jozef,

I just got thru doing something like this with a similar setup:
we use Emulex LP8000 cards for the HBA's onto an IBM 3584 with LTO drives
and a Mcdata switch. There are 4 things that need to be done or it won't
work:
0. Ensure that you've moved the /kernel/drv/st.conf somewhere else.
Solaris
will try and grab your scsi tape devices otherwise.
1. Make sure your fabric is set up correctly and that at boot up
(ck the /var/adm/messages files) you see your IBMtape device drivers and
HBA acquired targets. Here's a clip of what I'm talking about:

May  3 18:04:35 bst7-1 unix: IBMtape254 at lpfc1:
May  3 18:04:35 bst7-1 unix: IBMtape178 at lpfc1:
May  3 18:04:35 bst7-1 unix: NOTICE: lpfc1: Acquired FCP/SCSI Target 9 LUN
1
May  3 18:04:35 bst7-1 unix: NOTICE: lpfc1: Acquired FCP/SCSI Target 9 LUN
2
May  3 18:04:35 bst7-1 unix: NOTICE: lpfc1: Acquired FCP/SCSI Target 9 LUN
3

3. Next check that your /usr/kernel/drv/IBMtape.conf file has the
requisite
objects not #'d out. We typically leave all 16 instances open.
