IJ26901: LKU OR DLPAR FAILURE DUE TO HOSTRM SIGNAL HANDLING

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• AIX Live Kernel Update (LKU) or DLPAR attempts may fail
  due to the IBM.HostRM subsystem being unable to handle
  incoming signals while busy with other activity.
  On the HMC, this will result in errors similar to this:
   | HSCL294F The dynamic removal of processing resources
   | failed: The operation to remove processing has failed
   | on partition <partition ID>.
   | The OS standard output/error is not available.
   | The nested exception message is:
   | 2610-652 The command execution has exceeded the
   | allowable time limit (X seconds) has been exceeded.
  

Local fix

• As this is a timing issue, re-attempting LKU/DLPAR may
  result in success the next time.
  

Problem summary

• LKU or DLPAR may fail due to signal handling issues in HostRM
  

Problem conclusion

• The signal handling logic and related code has been improved
  to address the issue.
  

Temporary fix
