Hi James,
I went thru this 6 months ago, going from 8 lto2 to 4 lto3 and 4 lto2.
I can't say this is a complete procedure, but here are some key points.
Go to version 5.3.3.* for the server and device driver. lto3 media
isn't
recognized at a lower version.
My lto2 device classes had format=drive. This will make trouble in a
mixed
library. Change the lto2 devclass(s) to format=ultrium2c and restart
your
server. Since I run with 4 servers - 1 library manager and 3 backup
servers -
I had to stop all of them and restart the library manager first, then
the other
3.
Define new devclass(s) for lto3 with format=ultrium3c. Then define
drives and paths. After that, the server
and/or device driver knows what tape to put on what drive. Be aware
that while
lto3 tapes won't be mounted on lto2 drives, lto2 tapes will be mounted
on lto3
drives for both reading and writing.
My drives are all scsi, so I don't know if the scsi and fiber mix will
have
issues.
My servers are on Solaris with an STK l700e.
Hope this helps,
Bill Colwell

Subject: Mixed drives in a library
Anyone have any suggestions for how to add lto3 drives into an existing
library that has lto2 drives. I'm trying to figure out how to add the
lto3 drives / devclass for lto3 drives / new stgpools while at the same
time ensuring that the new lto3 media gets used by lto3 drives only.
Any ideas or suggestions are welcomed.
The tsm server is 5.2.7.3
aix 5.2 ML8
Lto2 drives : SCSI
Lto3 drives : fibre
Thanks,
James Choate
