Thanks Karel. But what confuses me is how the 0.0.0 specifies Bus 0, when the HBA properties says it is on bus 2?
How can I even tell which drive is connected to which HBA, except by tracing the cables? -----Original Message----- From: ADSM: Dist Stor Manager To: [EMAIL PROTECTED] Sent: 7/22/2004 11:33 AM Subject: Re: Windows drive addressing question... 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.

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
