Today, we actually run an AIX and Windows server to the same library, though they do use SAN connected drives, it has no bearing on the implementation because they are two distinct TSM servers not knowing about each other and not sharing drives.
The issue is more understanding how the 3494 categories work than anything. Make sure you are using the latest microcode (IBM engineering), drivers (Magstar FTP site), and patches to TSM. If you are not sharing any drives, then you just implement 2 separate TSM servers with different categories for the private and scratch tapes. Remember that 3494s get the first scratch category and 3590s get that number plus 1. So choose your numbers carefully. I typically chose something like 3500 for the private, 3501 for the scratch, 3502 is automatically assigned to 3590 when you turn on the parameter that says you have 3590s (recommend this implementation). Define both TSM servers to the library. Create separate Device Classes, some day you may want to share the drives. Actually, you could now if you used both SCSI ports on the drives. And, I believe at 4.1.3 you could share those drives with the right microcode level in the drives. If you want to use a common tape pool this is possible but then you will have to setup server to server communications and use drive mapping and sharing. -----Original Message----- From: Luke Dahl [mailto:[EMAIL PROTECTED]] Sent: Friday, January 04, 2002 8:48 PM To: [EMAIL PROTECTED] Subject: 3494 Library Sharing w/o SAN Hi Everyone, 3494 Library 6 3590 Drives 2 Sun Solaris Servers w/TSM 4.1.2 We'd like to share the 3494 library and I cannot find any good documentation on doing so. I've read through the redbooks and most discuss sharing through a SAN. Has anyone implemented this or a similar configuration? We'd like to dedicate three drives to each TSM server. We have configured the library manager to "shared" and the tsm parameters to share the library. We're about to bring the library online and am looking for any advice or known issues beforehand. The connection to the library is SCSI. If anyone can offer any assistance I would very much appreciate it. Have a great weekend! Luke Dahl NASA-Jet Propulsion Laboratory 818-354-7117
