Hi Rick, This question keeps coming up on the list, and I have never seen a definitive answer. But I will throw this out and see who can respond to it with better info -
"I think the answer is USUALLY NOT, and even if you somehow get away with it, it's not supported." To move client data across platforms, TSM provides EXPORT, which takes the client data and creates a "portable format" file that can be imported into the other platform. I think the reason a different platform can't read the tapes directly is the drivers. Take the more extreme case of going from HP/UX to Windows - how likely is it, really, that Windows tape driver will be able to read the data off a tape written by UNIX? On the other hand, in the closer cases of HP/UX to AIX, it probably depends on who wrote the driver, and what the driver expects to see (If your AIX box is available already, why not just try one and let us know?). A couple of years ago, I believe somebody on the list reported getting away with it when converting from OS/390 to AIX using a 3490-type tape. When he found he could read the tapes, he marked all the OS/390-written tapes as READONLY, just to ensure that all new tapes were written with the AIX drivers. But in that case, we know the drivers were at least written by the same vendor.... Anyway, as more than one person has posted today, moving with EXPORT/IMPORT is problematic if you have lots of data. But I believe it's the only supported way, and I am SURE Tivoli doesn't test or support the direct way. So much for my musings.... ************************************************************************ Wanda Prather The Johns Hopkins Applied Physics Lab 443-778-8769 [EMAIL PROTECTED] "Intelligence has much less practical application than you'd think" - Scott Adams/Dilbert ************************************************************************ -----Original Message----- From: Richard L. Rhodes [mailto:[EMAIL PROTECTED]] Sent: Tuesday, November 27, 2001 10:32 AM To: [EMAIL PROTECTED] Subject: TSM Platform Change What is involved in changing a TSM server from one platform (HPUX) to another (AIX)? I'm involved in a project that needs to move a TSM server from hp to ibm. I know the db needs exported/imported, unloaded/loaded, backedup/restored (I'm not sure how, but I've heard it can be done). The bigger question is the tapes. After a tsm db is brought to a new platform, can that tsm instance read the tapes that were created on the other platform? Thanks Rick
