Well, to speak on that as well, we just
had 8 new drives put into one of the libraries managed by this library
manager. We were told by TSM that you are not able to just define
new drives and paths to TSM because TSM is not going to recognize the element
numbers. We had to recycle the library manager so that TSM would
run an IOCTL and rescan the library and pick up the new drives.

Thanks for the "duh" suggestion. I know
how to get into the CE mode to
change the serial number and it would make life simpler. For this
drive,
since it was an "upgrade", this will work. However, for
new drives with
maintenance, I think they would frown on changing the serial #.
I still would like to know how other folks handle it if they can't change
the serial #.

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?
