IJ27249: DISK REPLACEMENT MAY FAIL WITH MISSING SLOT LOCATION DUE TO ECE DISK INVENTORY UTILITY PROBLEM

APAR status

• Closed as program error.

Error description

• The ECE disk inventory utility to list out all the
  disk slots in the system could hit an exception
  when one of the LSI adapters doesn't have a
  disk. This may result in the missing slot locations
  for the pdisks. The slot location is important to
  identify the disk drive in disk replacement, so it
  may cause the disk replacement to fail. If
  multiple disks fail without being replaced, it may
  risk the data reliability of the ECE storage system.
  

Local fix

• When disk replacement fails due to this problem,
  contact IBM support to apply work around steps
  for disk replacement.

Problem conclusion

• Benefits of the solution:
  Provide slot location for the disk drives, which
  can support the standard disk replacement
  process and identify the bad drives easily.

  When disk replacement fails due to this problem,
  contact IBM support to apply work around steps
  for disk replacement.
