What is the meaning of lpfc "FCP cmd x2a failed <1/0> status: x1 result: x0" (FCP_RSP_ERROR) messages on my log files?

Solution Verified - Updated -

Issue

  • I'm seeing various FCP cmd xN failed status: x1 result: x0 messages on log files after enable debug log level for Emulex HBA that uses driver lpfc, such as:
FCP cmd x12 failed status: x1 result: x3d
FCP cmd x28 failed status: x1 result: x1000
FCP cmd x2a failed status: x1 result: x0
FCP cmd x2a failed status: x2 result: x0 
  • Is result xNN a problem? What does this return code mean?

Environment

  • Red Hat Enterprise Linux 6.x
  • lpfc (Emulex) driver
