Found an interesting problem and am currently waiting on TSM Support to assist me but wanted to ask you guys. NT client platform. We have defined a SAN (Compaq Storage Works) to one of our NT Clients. The machine has a LOCAL C: and D: and the E:, F: and G: are disk from the SAN. On client version 3.1.06 the E, F & G: are seen as LOCAL drives, therefore the ALL-LOCAL domain statement in the dsm.opt file works with no problem. Then I upgraded to the 4.1 NT Client. I had no problems but now the client thinks that E: F: & G: are network and not local. These are hugh drives. I can barely get an incremental done (often times not) each night, let alone starting these over by creating new filespaces. It doesn't convert the 3.1.06 filespaces; it thinks they are brand new network ones. Anyone have any suggestions? Fortunately, I was able to reinstall the 3.106 client and run it on a nightly basis as the 4.1 client didn't touch those filespaces -- so the data isn't corrupted. My understanding from Support is that they knew this would happen.... I don't recall seeing any documentation on this. I'm waiting on them to tell me how to possibly convert these filespaces to a 4.1 format in the Network section without starting over. -Diana Cline
