It´s generation 1 drives, and the driver is the latest from IBM (September 2009).
I check in device manager and the driver version is 6.2.0.1 (3592J1A), and it even say in "Tape drive parameters" that Compression capable is TRUE, and Compression enabled TRUE. -----Original Message----- From: ADSM: Dist Stor Manager [mailto:[email protected]] On Behalf Of Richard Sims Sent: den 26 oktober 2009 12:28 To: [email protected] Subject: Re: [ADSM-L] 3592 drives no compression You didn't specify whether these were 3592 generation 1 or 2 drives. If gen 1, the 3592C you have set is the correct devclass specification. I would check that your tape device driver is the correct type, and is a recent vintage, to avoid any vagaries in passing device commands from TSM to the drives. Defects in drivers are not unknown. Likewise for tape drive microcode/firmware. See if you can find a utility to inspect the drive settings, to verify what they are. In AIX, the lsattr command can be used to verify if compression is in effect; I don't know what might be used in Windows.
