Hi Zoltan Some readme files says that data format changed in TSM 5.4 which is probably why you see this error. I have seen it in older versions of TSM when the backup process changed mgmtclass between directorypool and diskpool. Test not to use DIRMC?
An 'help 0536' indicates that we should follow the support matrix. :-) However this doesnt explain why you see the errors but more suggest where to spend the trouble shooting time. //Henrik -----Original Message----- From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] On Behalf Of Zoltan Forray/AC/VCU Sent: den 31 januari 2008 15:40 To: ADSM-L@VM.MARIST.EDU Subject: [ADSM-L] Strange ANR0536W all of a sudden Out of the blue, quite a few of my Windows clients are generating these error messages: 1/31/2008 3:30:37 AM ANR0536W Transaction failed for session 121443 for node ROSE-OTS (WinNT) - downlevel client does not support format of stored files. Considering the server hasn't changed since it was installed (5.5.0.0 eagerly awaiting first patches), I am trying to figure out what would cause these errors ? Yes, the clients are a little behind (5.3.x). A quick Google search did not reveal much on these errors. ------------------------------------------------------------------- The information contained in this message may be CONFIDENTIAL and is intended for the addressee only.
