    Physical volume "/tmp/snap.9vClRuKv/vgimport1" changed
    This occurs when the mount proxy host has logical volumes with
    the same logical volume group name as the target guest machine.
    
    Note:  This issue does not affect the Recovery Agent.
    
    Initial Impact: Low
    Tivoli Storage Manager Versions Affected:
    7.1.1 Linux
    Additional Keywords:
    TSM VM plugin
    | MDVPARTL 7.1.1.0-TIV_5725TVEVM |
    

Local fix

  • Rename the logical volume group name on the mount proxy host
    prior to mount, or use a mount proxy host without logical
    volumes.

Problem conclusion

  • The backup-archive client now verifies that only lvm devices to
    be mounted are including in the volume group rename process.
    The lvm devices are now correctly mounted.
    

Temporary fix

  • -Tivoli Storage Manager Client on Linux x86 7.1.1.1
    
    Note: Until a Data Protection for VMware packaged fix of a
    fixing TSM Client level is available, Data Protection for VMware
    customers can install an use a fixed level of the the TSM Client
    in their environment.
