Notification Time: Fri Nov 10 17:15:07 2017

taopdmw1 sent Event Monitor notification information:

/adapters/events/ql_adapter/0_5_1_0 is >= 3.
Its current value is CRITICAL(5).



Event data from monitor:

Event Time..........: Fri Nov 10 17:15:07 2017
Severity............: CRITICAL
Monitor.............: dm_ql_adapter
Event #.............: 59
System..............: xxx
 
Summary:
    Adapter at hardware path 0/5/1/0 : Target device is back. Port World-wide
    name remains the same as original.



Description of Error:


lbolt value: 347928015

  Target with device id 0x10300 is back in the Name Server GPN_FT (FCP type)
  response. And the 'Port World-wide name' remains the same as original.
         device id = loop id, for private loop devices
         device id = nport ID, for fabric/public-loop devices


Probable Cause / Recommended Action:

    This is a paired message with "Target device is lost in the
    Name Server GPN_FT response".
    On receiving another RSCN, driver sent Name Server GPN_FT request
    to obtain all the FC-4 type device information in the fabric.
    Driver has detected that a previously lost device (Nport_id)
    is back in the GPN_FT response, or it's corresponding World-Wide
    Name remains the same.

    Driver will be able to communicate with the device.
    No action is needed.

Re: Target device is lost in the Name Server GPN_FT response

This is likely due to changes made in your SAN switch or in the disk array. Contact your storage administrator to look to SAN logs and identify the changes made when the messages first appeared,

Many thanks!

Log has indicated "No action is needed". Is it correct?
