You are correct in that the TS3500 (3584)'s drive WWN are tied to the Drive
Cage. But the serial number goes with the drive. But the FE are supposed to
move the old drive's serial number into the replacement drives for LT03 and
higher.

Dumb ? - But I was under the impression that the TS3500 (3584)'s drive
Serial Numbers were tied to the Drive Cage (rail) so the SN and WWN were
static... Maybe I'm thinking 3494 w/ 3592 Drives.

We use LTO2 & LTO3 in a 3584 and the CE always sets the serial number to
match the old one so that we don't have this problem, same as Sean.

In fact we found out that for lto-3 and lto-4 tape drives in an IBM 3584
library, it is required that they change the serial number to match the
old tape drive. Because IBM tracks the drives by serial number for maint
contracts. This we found when the serial numbers that we send in for a
maint contract renewal were kicked out as field engineering had not
been updating the serial numbers. But not for lto-2 tape drives.

Zoltan,
The majority of our TSM servers are AIX and we do have a setup where we
share multiple library clients with one library. When we have IBM CEs
come out and replace drives, they just change the serial number on the
new drive to match the old drive they are replacing. Apparently there
is a way to do that on the drive itself.
Thanks,
Sean

[ADSM-L] Replacing tape drives (or "there has to be a better way")
I need thoughts/suggestions/help on how to deal with SAN attached tape
drive replacements when a library is shared amongst 5-servers.
We just has a drive replaced, therefore giving us a new serial number
(3494ATL - TS1130). All servers that use these drives/libraries are
RedHat Linux and use very current lin_tape drivers.
Currently, the method we use is to bounce each server so the system
rescans the SAN and gets the new serial number.
In the past, just stopping the TSM server and then restarting the
lin_tape driver would often be enough. Now with the latest lin_tape
drivers, I don't see the lin_taped daemon running any more.
Yes, I have tried updating the paths on the library manager server and
telling it to autodetect but that didn't help.
There has to be a better way! If you have a similar configuration, how
do you handle this scenario?
