IC60600: NAS OPERATION INITIATED FROM A LIBRARY MANAGER MAY FAIL WHEN USING A SHARED DRIVE

IBM Tivoli Storage Manager V6.1 Fix Pack 3 (6.1.3) Server Downloads

APAR status

• Closed as program error.

Error description

• In some situations, when a TSM library manager server detects
  an error on a tape drive, the library manager may set a drive
  path offline instead of setting the drive offline. This is to
  prevent any library clients from using the drive. However, since
  NAS operations do not use the path originating from the
  library manager, this does not prevent the drive from being
  selected for a NAS backup or restore to a locally attached
  (not NDMP filer-to-server) device.
  -
  Therefore, if the drive is also shared with a NAS datamover, the
  library manager may still select the drive for use during a
  NAS operation, and in this case the operation using the drive
  will fail instead of using another drive. If the drive was set
  offline by the TSM server, the datamover would not attempt to
  use the drive.
  -
  These errors may be received:
  ANR8779E Unable to open drive /dev/rstXX, error number=5.
  (SESSION: XXXX)
  ANR8965W  The server is unable to automatically determine the
  serial number for the device.  (SESSION: XXXX)
  TSM Versions Affected: All supported TSM servers
  Initial Impact: Medium
  Additional Keywords: zz61

Local fix

• Update drive to offline, fix the drive.
