dmesg error

himacs — Sat, 30 Oct 2010 08:04:47 GMT

The dmesg shows below error.

0/3/1/0/4/0: Device at device id 0x11400 has disappeared from Name Server GPN_FT
(FCP type) response, or its 'Port World-Wide Name' has changed.
device id = loop id, for private loop devices
device id = nport ID, for fabric/public-loop devices
System won't be able to see LUNs behind this port.

0/3/1/0/4/0: Device at device id 0x11400 is back in Name Server GPN_FT (FCP type)
response, and its '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
System will be able to see LUNs behind this port
(might need to run 'ioscan' first).

Syslog have below line..

Re: dmesg error

SunnyS — Mon, 01 Nov 2010 14:46:49 GMT

GPN_FT is a standard Fibre Channel protocol request. It is used by a FC port to query a FC SAN switch to get the list of other FC ports on the SAN (name server database). If zoning is enabled, then the FC SAN switch response includes only those ports that are in the same zone(s) as the requesting port.

There could be multiple reasons why a port may have disappearred from the GPN_FT response. Most likely the port went offline (this could happen, again, due to multiple reasons - cable was unplugged, disk array crashed or rebooted, etc.).
