IV88588: IOCTL COMMANDS MAY FAIL AFTER LINK DOWN/UP EVENT ON EMULEX 16GB APPLIES TO AIX 7100-03

APAR status

• Closed as program error.

Error description

• IOCTL commands such as SCIOLPAYLD issued on behalf of an
  NPIV client may fail with ENETDOWN (rc=69).  This may
  be seen while executing LPM, but is not limited to LPM.
  Running fcstat against the physical adapter on the VIOS
  shows the physical link is up.
  
  This can occur after a link down/up event on the Emulex
  16Gb FC adapter.
  
  An inspection of the NPIV client's initiator structure
  in kernel memory will show the state as 0x1000 or 0x0008.
  

Local fix

• Workaround is to unmap the vfchost adapter, then re-map
  it.
  

Problem summary

• IOCTL commands such as SCIOLPAYLD issued on behalf of an
  NPIV client may fail with ENETDOWN (rc=69).  This may
  be seen while executing LPM, but is not limited to LPM.
  Running fcstat against the physical adapter on the VIOS
  shows the physical link is up.
  
  This can occur after a link down/up event on the Emulex
  16Gb FC adapter.
  

Problem conclusion

• Code to handle link up event is corrected to avoid the
  failure of further IOCTL commands.
  

Temporary fix
