That's true, I should have qualified my statement to say I've had no reason to do that on AIX or Windows TSM servers.
The tape management is different for OS/390, and many people use different device classes for just the reason you noted. -----Original Message----- From: Matthew Lynch [mailto:[EMAIL PROTECTED] Sent: Wednesday, June 25, 2003 1:57 PM To: [EMAIL PROTECTED] Subject: Re: Device Class We have different device classes simply to assign a different dataset name prefix to the offsite volumes. We then use the DSN prefix as our selection criteria for ejecting the volumes from the STK silos .

Here in our site, we used single device class for primary & copy pools. Any feedback is really appreciated. Thanks. Zosi Noriega Analyst, Data Storage P.O. Box 898 ADNOC AUH UAE 009712 6024987
