IBM Tivoli Storage Manager V5.5 Fix Pack 6 (5.5.6) Server Downloads

APAR status

• Closed as program error.

Error description

• The Tivoli Storage Manager server has problems sending a
  LUN reset to a SCSI tape driver.
  
  The LUN reset should work for a SCSI tape device which is
  configured by the Tivoli Storage Manager tape device driver
  or the IBM tape driver with install_exclusive.exe
  without -p option (without Persistent Reserve feature enabled).
  
  The LUN reset is not suitable to reset a tape drive which is
  configured by the IBM tape driver with the Persistent Reserve
  feature enabled.
  
  This occur under the following conditions:
  
  - A tape drive is connected to a SAN.
  - Two host systems are connected to the same SAN.
  - One of these two host systems must be a Windows platform
  - For the Windows platform, this tape drive is configured by
    the Tivoli Storage Manage kernel device driver or is
    configured by the IBM tape driver with install_exclusive.exe
    with -p installation.
