Apologies. The device class definition can tell TSM that compression is to be used on a given tape drive(s). However, compression must be turned on at the OS level before the device class definition can be used. I'm sure that Solaris has a setting to turn compression on, just as AIX does, but, like Richard, it is also beyond my experience. -- Mark Stapleton ([EMAIL PROTECTED]) Berbee Information Networks Office 262.521.5627
