IC73252: NOT GETTING THE EXPECTED NUMBER OF LIBRARY INVENTORY SLOTS

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

APAR status

• Closed as program error.

Error description

• Tivoli Storage Manager calculates the max element slots by
  calling two device driver  calls.  First, to get the library
  element count.  Then, the device driver will request the
  inventory information for the number elements returned by the
  library element count.  If this is successful, Tivoli Storage
  Manager will be able to utilize all of the discovered slots.
  
  Example:
  If element count reports 9000 slots, the device driver will
  request inventory for 9000 slots.
  
  There are currently limitations due to the max transfer length
  of the HBA and the OS architecture (DMA max size).  Both of
  these max DMA sizes need to be taken into account within the
  Tivoli Storage Manager device driver.
  
  To identify this problem, get the device driver trace.
  
  Example:
  cd /opt/tivoli/tsm/devices/bin
  rm ddtrace.out  (deletes old trace file)
  ddtrace start librarydd
  ./lbtest
  select 1: Manual test
  select 1: set device special file (enter your /dev/tsm_lb device
  name)
  select 6 : open
  select 8 for element count
  select 9 for inventory
  select 99 to return to main menu
  select 9 to exit lbtest
  ddtrace get librarydd
  ddtrace end librarydd
  
  The new ddtrace.out will have message:
  ps_scsi_execute: scsi_transport failed transport_rc = -1
  (This is: package is too large)
  
  Initial Impact: Low
  Additional Keywords: max transfer length  zz61 zz62 TSM
