Error description

  • Tivoli Storage FlashCopy Manager and Data Protection for
    Microsoft Exchange Server and Microsoft SQL Server restore
    operation from a VMVSS backup may terminate with ANS1086E due to
    iSCSI mount failure even though the Recovery Agent has exposed
    the correct disk. The root cause is the wrong determination of
    the partition index. APAR IT15207 addressed similar problem but
    at the backup stage. The problem there was that partition index
    for mountpoints were not matching due to the fact that the
    recovery agent enumerates partitions in a sequential order,
    whereas application protection code obtains partition indexes
    based on VDS disk offsets. The change in IT15207 was to move to
    enumerating in a sequential order in the injected code when
    generating APPPROTECTIONDBINFO.XML, just as the RA does. This
    change was only made in the backup process which was enough for
    the FBVV driver. However after switching to iSCSI, restore
    processing now requires similar code changes to figure out the
    partition index we need to mount from a disk.
    
    Products affected:
    IBM Spectrum Protect Backup-Archive Client version
    7.1.6.2 and later on Windows
    Note: The Backup-Archive Client is a prerequisite to using the
    Data Protection for VMware. In Data Protection for VMware
    environments, the Backup-Archive Client is also known as the
    data mover.
    
    This problem also affects IBM Spectrum Protect for Virtual
    Environments: Data Protection for VMware 8.1.0. If you are using
    Data Protection for VMware 8.1.0, refer to APAR IT19834.
