Thanks, everyone, for the replies. We have 13,000 VRSs between two sysplexes. We're in the process of removing the unnecessary ones (90%?)and combining some. Most came as part of the migration from TLMS.
Again, my thanks for your replies. I'll be changing VRSMIN to around 1000 to start with. -----Original Message----- From: Mike Wood [mailto:[email protected]] Sent: Tuesday, April 13, 2010 1:31 AM To: [email protected]; David G. Schlecht Subject: Re: RMM and VRSMIN David, Consider that the loss of just a single VRS could cause you to lose a lot of data. So, the problem is not about losing/deleting 1000s it is about avoiding loss of data. RMM provides multiple options to help with this: VRSMIN allows you to identify a value which you identify as the critical number of VRS. This might be ALL of your VRSes. Some one with just a small number may feel the count should match there number of VRSes. If you have 1000s, which I wouldnt recommend ;-), and you look to VRSCHANGE - you could perhaps do what Tom suggests. VRSCHANGE This is a way to enforce a 'trial run' of VRSEL should anyone add/change or delete VRSes. Using this option might make the VRSMIN count less important VRSRETAIN, VRSDROP, EXPDTDROP These more recent options provide a way to direct rmm to detect when result of retention are not what you would normally expect. RMM provides these options because of the cost of data loss, and the effort required to retrieve data that has been scratched prematurely. We have to think about deliberate actions, accidents, and code defects as the possible triggers. Mike Wood RMM Development On Mon, 12 Apr 2010 10:50:49 -0700, David G.

But, for the life of me, I just can't see a benefit for this. Looking over the books, this seems that it would only benefit us in the event someone accidentally deleted thousands of VRSs and this just doesn't seem accidentally feasible. > >Is it possible to accidentally delete thousands of VRSs? It appears the DELETE VRS panel doesn't allow a generic VRS Name and the Data set mask only applies to one VRS so what's the worry? What am I missing?
