Win2K & Win2003 - Data Currently Unavailable On Server

This past weekend we performed a DR test on quit a few servers and discovered a situation that was a wake up call for anyone still using Windows 2000 or Windows 2003. The issue is that when we ran a restore the IBM Spectrum Protect 8.1 server issued a warning on all the files for the particular node with the following message type…

ANE4035W (Session: 79, Node: ODC-WINCS-1-DR)  File '\\od-wincs-1\e$\834\c-oh\files-20170823-123000' currently unavailable on server.

The tape was in a readonly state and accessible by the library so it was not a tape unavailable problem. I then querried the file and ran some tests suggested by IBM in the following link

http://www-01.ibm.com/support/docview.wss?uid=swg21249032

The data is present and on tape but TSM will not restore it. (See the queries below) IBM would not help us because the OS is unsupported as is the TSM client. We could not restore the System State, System Services, or any of the Data to the DR replica. What we could do is access the data from a supported client level on a supported OS level (i.e. TSM Client 6.4 from a Windows 2008 server). We were unable to recover the Win2K/Win2003 servers during the DR test and unfortunately I know many companies out there still have some of these servers in their environment. It's time to upgrade! Your data is at risk!

  1. I do not think this is the result of an imposed restriction. Rather, it looks like a known APAR, IT19033. Take a look at https://www.ibm.com/support/docview.wss?uid=swg1IT19033 which describes the issue, workarounds, and fixing server levels.

  2. Andrew,

    I had found this APAR when trying to diagnose the issue and when TAPEPROMPT and the VERBOSE options did not resolve the issue I was left without any recourse since the client was an unsupported version (5.4 and 5.5) and IBM could (would) not help us.

    1. Chad,

      I did some checking, and found that for IT19033, the workarounds were not always effective. Thus that APAR should not be ruled out. The next step should be to upgrade your server to a fixing level, then try the restore again.

      I also found your support case, and it is still open. If the fix for IT19033 does not resolve the issue, we can continue to pursue it through that support case.

  3. Sooooo..... I kind of don't want it fixed. The customer is using old unsupported OS (Windows 2003) and very old TSM clients. We were performing a "DR" at Sungard with limited time available. I would have considered upgrading the TSM server but at the time it did not appear to be the issue. The good that came from this is that the customer is taking more seriously their need to upgrade to supported OS and TSM versions. I will notify the team about the issue and how to possibly avoid it in the future since we were definitely on a non-fixed level (8.1.0). I really appreciate the input and help. Thank you!
