FYI, v5.1 supports server-2-server export-import in a single step; you no longer need to run the intermediate data thru virtual volumes --- it works abit like CMS-pipelines, once you get it setup on both sides, data flows from server-a (node-data-on-tape input) to server-b (new-node-data-on-new-tape). It's still a pain, but only half as much as pre-5.1 days.
Also, there was an earlier post, sometime in the last year, where someone successfully transferred their TSM db from one Unix flavor to another... don't recall who (or how), but they reported success!@!

It's just a pain to set up, and takes QUITE some time: You have to read the data on your source system (EXPORT), transmit it to the new server via TCP/IP, which writes it out on your target server; then you reimport it to the target server, which reads it again and writes it out to the target storage pool. -----Original Message----- From: Allen Barth [mailto:[EMAIL PROTECTED]] Sent: Friday, November 22, 2002 11:50 AM To: [EMAIL PROTECTED] Subject: Re: Migration from AIX to Solaris Wanda, I agree with what you've stated, and will admit I hadn't thought it through to the tapes. But as you say even if it did work, it would be unsupported. I thought I read something somewhere about a 'no tape server to server export/import' feature. That would aid moving the data and rebuilding the db, but it would still take some time to finish.

What you describe will work going from AIX to AIX, but if it works going from AIX to Solaris, it's an unsupported accident. The other issue is the data that exists on tape. If you were able to NFS mount the DB to Solaris and use it, then what happens when you try to do a RESTORE? You are using a TSM-on-Solaris tape driver to read data that was written with TSM-on-AIX tape drivers. I don't know if that is feasible and again, it isn't supported if a problem does occur. I've heard that somewhere in 5.2 or higher Tivoli is planning something to help moving a server across platforms, but we aren't there yet. -----Original Message----- From: Allen Barth [mailto:[EMAIL PROTECTED]] Sent: Friday, November 22, 2002 11:22 AM To: [EMAIL PROTECTED] Subject: Re: Migration from AIX to Solaris Are you saying that the internal format of the db changes between OS's? If not, I wonder if this would work: Install ITSM on Solaris Export filesystems on AIX containing db and log areas NFS mount those filesystems to Solaris Update dsmserv.dsk on Solaris to point to NFS db and log areas Insights, ideas, gotcha's all welcome.

You can EXPORT the definitions, like policies, mgmt classes, schedules, admins, etc. and reimport them to the new server; you can EXPORT and IMPORT the client data as well, but this is really rebuilding the DB on the new server as the IMPORTS occur; and it's obviously time-consuming. There are two ways to approach the move: some people just start backups on the new server, leave the old one around for a while until the data ages enough to be useless, then shut it down. Other people try to do the EXPORT/IMPORT thing. Your decision will depend on your circumstances, how much time you have, and how much backup & archive data. To do the EXPORT/IMPORT, you either have to have compatible media, or use server-to-server virtual volumes to transmit the data from one TSM server to the other. (This requires a DRM license, I think for the target server.) As far as using the same library, the answer is "probably". I don't know if you can share the 3583 with TSM library sharing, if so that would be ideal as it would let you use the drives as needed. The other alternative is to physically share the library and dedicate some drives to the new server and some to the old server until you get all the data moved. Don't know enough about the 3583 to get further than that. That's hardly a complete answer, but maybe it will get you on the road to the next set of questions.... ************************************************************************ 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: Doug Baker [mailto:[EMAIL PROTECTED]] Sent: Friday, November 22, 2002 8:42 AM To: [EMAIL PROTECTED] Subject: Migration from AIX to Solaris Hi everyone, Currently we're running TSM 4.2.3.0 on AIX, attached to an IBM 3583 library. I'm curious about the prospects of migrating the TSM system from AIX to Solaris. 1. Is it feasible to do this with the same library? (does the existing data on the 3583 tapes need to be converted, or can a TSM database be exported from AIX to Solaris, and the new server read from the existing data?) 2. Is there a guide to doing this with the new versions of TSM? I recall folks talking about an old ADSM Redbook, but I don't know if the same rules apply to TSM. I imagine this is a vast topic, so I'll start with these questions. Thanks! Doug [EMAIL PROTECTED]
