Error description

  • Tivoli Storage Manager Client 6.4 may crash when restoring VM
    that has independent disks.
    
    Problem Description:
    When doing "RESTORE VM" using the Tivoli Storage Manager Client
    6.4, dsmagent.exe may crash.
    
    The problem can happen only when the following conditions are
    met:
    - The target VM has independent disks.
    - The backup VM was taken with
    "-vmprocessvmwithindependent=yes" by Tivoli Storage Manager
    Client 6.3.
    
    Here is the call stack from the crash dump.

    Tivoli Storage Manager Versions affected:
    Tivoli Storage Manager Client 6.4.0 on all supported platforms.
    
    Additional Keywords:
    Independent disk, RDM disk, VMware
    
    Additional L2 info:
    The problem is that Tivoli Storage Manager 6.4 client does not
    properly exclude independent disks from restore.  The issue
    occurs because in 6.3 the exclude process for independent disks
    was different: in 6.4 a selected status for each disk was
    added, which indicates if the disk was excluded by the user,
    due to being rdm/independent.
    
    Initial Impact:
    High
    

Local fix

  • Use "-vmdk" option to manually exclude independent disks during
    restore.
