Wanda,
mt 0.0.0.x = Target ID 0, Lun 0, Bus 0. The X is auto assigned by Windows based
on the time of first detection. At least, this is how I resolved it by looking
at the LB.x.x.x. info.
Regards,
Karel

Subject: Windows drive addressing question...
A question for you Windows heavies out there.
I have a Windows TSM server with a very simple tape configuration.
In the Windows host there are 3 fibre HBA's. Each one is connected by a
fibre cable to one of three 3590 tape drives in a 3494 library. NO switches
involved, just a fibre cable direct from each HBA to its tape drive.
(The 3494 library itself communicates via Ethernet, so it isn't involved in
this addressing question.)
I set the drives up using the TSM Device Configuration Wizard and everything
works great. I just don't understand how the Device Configuration wizard
works.
- If I go to My Computer -> Manage -> Device Manager and look under SCSI &
RAID CONTROLLERS, I see 3 entres for
"IBM Netfinity QLA220 PCI Fibre Channel Adapter", which is what I expect to
see. If I look at the properties for the 3 adapters, I see
Location 5 (PCI bus 2, device 5, function 0)
Location 2 (PCI bus 5, device 2, function 0)
Location 3 (PCI bus 5, device 3, function 0)
If I look in Device Manager under Tape Drives, I see 3 entries for
"IBM 03590E1A SCSI Sequential Device", which seems reasonable. If I look at
the properties for the 3 tapes drives, what I see is a bit confusing:
Bus 0, Target ID 0, Lun 0
Bus 0, Target ID 0, Lun 0
Bus 0, Target ID 0, Lun 0
And the TSM Device Configuration Wizard sees the tape drives as
mt0.0.0.5
mt0.0.0.6
mt0.0.0.7
Can somebody explain to me:
1) how do these 3 sets of addresses relate to each other?
2) how does the TSM Device Configuration wizard come up with the names
mt0.0.0.5 , mt0.0.0.6, mt0.0.0.7?
Any help in reducing the confusion is much appreciated!
Wanda
