If one is using the ibm 3584(aka TS3500) then the wwn does not changes on a straight up swap-out. The wwn goes with the slot in the library used to hold the tape drive and not the tape drive itself. And with lto-3 tape drives and better, Our IBM ce's have to update the new tape drive with the old tape drive's serial number as the maint contract tracks enablement by the original serial number. So neither the wwn or serial numbers change.

"Gill, Geoffrey L." <GEOFFREY.L.GILL@ To SAIC.COM> [email protected] Sent by: "ADSM: cc Dist Stor Manager" Subject <[email protected] LTO drive replacement when using .EDU> switch zoning 08/18/2009 07:56 PM Please respond to "ADSM: Dist Stor Manager" <[email protected] .EDU> Hi all, This situation has never happened to me before so I'm a little unsure of the steps and order to fix it. Running AIX 5.3 with a TSM instance at 5.5.1. LTO drives are zoned in through a switch to the TSM server, 2 drives to each fibre card. Support for the IBM drives was not renewed with IBM so it looks like this new group has no idea how to 'fix' drives and would rather replace them, something that 'never' happened with IBM so I'm not quite sure exactly what needs to be done to get this drive back online. I know the references in TSM need to be updated so I have removed the path and drive. When adding them back the path failed so it seems like I need to get AIX to see the new drive and not sure if I also need to do anything on the switch. Unfortunately, or maybe fortunately, I typically have no issues so it's hard to gain and keep knowledge when 98% of the time I'm "watching" the system instead of "doing something" with it. Since I don't have a test system built similarly I can't play around and create documents to refer to when the 'what did I do when that happened' scenario comes up. Thanks for any advice you can provide.
