Eric, You are right about those statements. But the thing that scares me, is that it is at all possible to connect as an AIX node to TSM, using windows TSM client software, regardles of the version. You can train users to any extend, but you cannot always predict the actions they will take. What i would like to see, is that the TSM server prevents the update in the database for a specific node when the client platforms don't match, or when there is only read actions involved. Like queries or restores.

I don't think it's a filespace renaming problem. I think you are running into the fact that once you connect with a newer client version, you can't go back to an old version. This is stated in the readme: - Data that has been backed up or archived from a TSM V4.2 client using the encryption feature, or from any TSM V4.2 Windows client, cannot be restored or retrieved to any previous level client, regardless of the TSM server level. The data must be restored or retrieved by a V4.2.0 or higher level client. Personally I don't see this as a bug. One just should not connect to TSM pretending to be another user as long as you are using different client levels or OS.

Coolen [mailto:[EMAIL PROTECTED]] Sent: Wednesday, May 15, 2002 17:08 To: [EMAIL PROTECTED] Subject: Virtualnodename issue concerning Windows and AIX Hello there, We stumbled onto the following problem, the hard way i may add. We have a mixed environment using AIX, Windows NT/2K and Sun Solaris. The Sun and NT boxes all run a very recent TSM client level. Some AIX boxes are running TSM client code by now as well, but most of the aren't on AIX 4.3.3 yet, so we can't upgrade them all. Our TSM server runs on AIX 4.3.3.x at level 4.2.1.9. Here comes the problem. One of our DBA's connected to TSM server using a windows tsm client, pretending to be a certain AIX node. Due to the optionsettings, the AUTOFSRENAME action kicked in, updating the FS information on that AIX box. The q node showed the following. tsm: ABPTSM1>q node rs6sv090* Node Name Platform Policy Domain Days Since Days Since Locked? Name Last Acce- Password ss Set ------------------------- -------- -------------- ---------- ---------- ------- RS6SV090 AIX DOMRS_TST <1 <1 No RS6SV090Z WinNT DOMRS_TST 1 182 No The *Z node is the renamed version, so we could continue the backups to the original node name, being rs6sv090. As you can see, the *Z AIX box is shown as a NT box. Huh?! When connecting the original node from the AIX command line, we are told that the client is down-level, so we cannot connect. No backups or restores are possible using the original node. No backups or restores are possible from any AIX node, no mather which client code we run. To make the original data available, we exported the *Z data, and imported it into the original nodename, without updating the client information using the replacedefs=no option during the import. This took a while though. I think it's not such a good functionality, that we can use a windows tsm client to connect as an AIX box, rendering the AIX data unavailable. To me, this feels like a BUG. I'm working on the following questions: Did any of you run into such a problem too? Does anyone know of a way to prevent someone from performing the connect like this? Is this problem known to Tivoli? If yes, what is being done on this issue? Any comment is appreciated. kind regards. Ilja G.
