OK, the plan to implement private volume sets on an active system is as follows: * Do a full volume backup of my system with the following command: ! STORE @[log in to unmask]@;;& ! STORESET=(*FBKUP1),(*FBKUP2);INTER;& ! DIRECTORY;COMPRESS=HIGH;MAXTAPEBUF;PROGRESS=1;SHOW * Then I will use VOLUTIL to create a new volume set and to add members to it accordingly. * Next I will use BULDACCT to create job streams to migrate accounts to the new volume set. * Naturally, I will then stream the BULDJOB1. * Take the system down and do a RELOAD from the Back-up created above. * Stream the BULDJOB2 to reset UDCs. So can anybody that has gone through this process please review this and let me know what I have missed? It would be greatly appreciated. Thanx, Jon Backus HP System Manager AB&C Group
