Welcome to Microsoft's inability to handle SANs! Seriously, Windows has no facility to persistently bind devices and definitions on a fiber-connected device. That's what you're seeing--whenever there is a discontinuity between a Windows server and its fiber-connected devices, there may (probably will) be a renaming.
My understanding is that the TSM 5.3 server suffers much less from this issue. -- Mark Stapleton ([EMAIL PROTECTED]) IBM Certified Advanced Deployment Professional Tivoli Storage Management Solutions 2005 IBM Certified Advanced Technical Expert (CATE) AIX Office 262.521.5627 >-----Original Message----- >From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] On >Behalf Of Prather, Wanda >Sent: Friday, June 10, 2005 2:10 PM >To: ADSM-L@VM.MARIST.EDU >Subject: Windows and device addressing for TSM (Make it stop!!!) > >Could use some help from any Windows gurus out there: >HOW do I keep Windows from changing the addresses of the TSM devices? > >This server is Win2K3 (but the same thing has occurred on >Win2K), TSM is 5.2.2.5. > >There are fibre connections from 2 HBA's to 2 different SAN switches. >1 Fibre cable from each SAN switch to 1 LTO drive in a 3583 >(that way if we lose a switch, we can still access at least 1 drive). > >Yesterday in order to clean up a big tangle of fibre cables, >the Windows admin disconnected 1 fibre cable from the HBA, >untangled things and plugged the cable back into the HBA, >EXACTLY the same connection.
