Hi Richard There is no need to define a logical library. This is what device classes are for,
Define a device class for just LTO3 and another for just LTO4 and set up new storage pools to use them. Unfortunately you can't update a stgpool's devclass, so there is some work there. Exports, generate backupset and backup DB all have a devclass option so they can be directed to LTO3. The only downside is that you need to watch your scratch usage a bit more closely as you can have LTO3 scratch in the library but no LTO4 or vice-versa. Run select mediatype, count(*) from libvolumes where status= 'Scratch' group by mediatype to keep track of this, Steve Steven Harris TSM Admin, Sydney Australia "ADSM: Dist Stor Manager" <[email protected]> wrote on 19/11/2008 01:47:34 AM: > I just reread your original post, realized you are removing all the LTO3 > drives, correct? > I don't know if you can (safely) define your LTO4 drives to multiple TSM > libraries. > > What you could do instead, is check the LTO3 cartridiges in as PRIVATE > instead of scratch, then run your EXPORTs with a FILE: parm to list the > volumes to be used. > > > > On Tue, Nov 18, 2008 at 9:04 AM, Cheung, Richard > <[EMAIL PROTECTED]>wrote: > > > A 3584 with 4 frames, looking to add 1 or 2 more frames at present... > > > > > > -----Original Message----- > > From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] On Behalf Of > > Wanda Prather > > Sent: Wednesday, 19 November 2008 12:24 AM > > To: [email protected] > > Subject: Re: [ADSM-L] using different media for permanent offsite copies > > > > What kind of library do you have? > > > > (What you are suggesting usually works just fine.) > > > > > > > > On Tue, Nov 18, 2008 at 8:31 AM, Cheung, Richard > > <[EMAIL PROTECTED]>wrote: > > > > > Hi all > > > > > > Need to know if this is feasible as an idea.. > > > > > > We are about to move to a LTO4 media library instead of LTO3s - by > > > replacing the remaining LTO3 drives we have with LTO4s... by marking > > > the existing LTO3 tapes all 'read only' and putting in LTO4 media for > > > write operatons etc, eventually our library should then only be > > > comprised of LTO4 media, with LTO3 media expired and can be removed > > from > > > the library. > > > > > > We are going to have an enormous amount of LTO3 media after this which > > > we wont use for the normal backup cycle.
