That may well be the key. I don't use collocation on my TDP/R3 stuff because they run direct to tape anyway and I've different management classes and storage pools for production and other environments. For one thing, the other environments don't get copied for off-site storage because the D/R recovery process is to do a restore from production (which we do about 6 to 8 times per year anyway). This isolates the production tapes into one pool for storage pool backup purposes.
I also have two additional pools for the redo logs (disk and tape both) with seperate management classes. I do use the same pools for all environments here, because production generats about 14 to 22 GB per day (per pool) and the test, dev, and sandbox environments combined tend to be under 600 MB per day. TSM seems to be like perl -- there's more than one way to do it! And, like perl, some of the ways are uglier than others :-) Tom Kauffman NIBCO, Inc > -----Original Message----- > From: John Monahan [mailto:[EMAIL PROTECTED]] > Sent: Tuesday, July 23, 2002 11:05 PM > To: [EMAIL PROTECTED] > Subject: Re: TDP R/3 > > > Same here, but the only way I've been able to use multiple > drives with a > single mgmt class is with collocation OFF.
