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 Draper Lab -----Original Message----- From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] On Behalf Of James Choate Sent: Wednesday, October 04, 2006 11:44 AM To: ADSM-L@VM.MARIST.EDU 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 Os aix 5.2 ML8 Lto2 drives : SCSI Lto3 drives : fibre Thanks, James Choate
