Probably because it it was supposed to save $$$. Isn't TSM supposed to "work better" or at least be easier to manage on open systems? Maybe that is just a perception I've heard around here because the TSM admin(s) work mostly on *nix. Also, 90% of other TSM workloads are on AIX. One particular workload (TSM to backup AIX SAP servers) was on AIX but moved to the mainframe when we consolidated our mainframes out to LA. The SAP AIX servers moved along with the mainframe (because of how "tightly coupled" they were with the MF) but the AIX TSM servers remained in the Chicago area since they were still being used with all the other AIX servers that were staying. TSM was already in use on the MF for LPARs that already existed in the LA data center, so we just implemented it on an additional LPAR to backup SAP AIX. Oh, did I mention it was supposed to save $$$? On another note... I tried to go back and look for any responses to my question about linux success stories or war stories. Only found the one from Alan at Supervalue (but he didn't mention anything about how "on-time" the project was or how smoothly it ran). I know there are many others success stories and others similar to my experience. I'm surprised there were not more responses from IBM-MAINers. I did note that the 2 threads went far off topic from the subject line.... but what else is new?
