IV02947: DELAY IN NPIV CLIENT SHUTDOWN AND RECONNECTION APPLIES TO AIX 6100-07

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Shutdown of NPIV clients may suffer delays when target ports
  have left the SAN or are unresponsive.  In some cases, NPIV
  clients may be unable to reconnect to the VIOS for a time
  because a previous NPIV shutdown request is still active on
  the VIOS.  The old shutdown request will eventually finish,
  but the client NPIV connection will be unusable in the mean
  time.  This could result in NPIV client boot failures.
  
  This problem is specific to NPIV.  The fix for this APAR
  applies to the VIOS only; it is not required on the clients.
  

Local fix

Problem summary

• Shutdown of NPIV clients may suffer delays when target ports
  have left the SAN or are unresponsive.  In some cases, NPIV
  clients may be unable to reconnect to the VIOS for a time
  because a previous NPIV shutdown request is still active on
  the VIOS.  The old shutdown request will eventually finish,
  but the client NPIV connection will be unusable in the mean
  time.  This could result in NPIV client boot failures.
  

Problem conclusion

• The driver is updated to avoid sending LOGO ELSes to SAN
  targets used by NPIV clients when the client is shut down.
  This prevents the possibility of a LOGO ELS suffering a time
  out.  This applies only to logouts that are the result of
  a client shutdown.  A client can still explicitly request that
  a LOGO be sent to a particular SAN target.
