SAN/HBA failure in syslog

[Rick vonR]

I am receiving the following errors in the syslog file. The errors only last for a few minutes then come back.

Feb 18 18:17:09 gput49 vmunix: 3/0/6/1/0/4/0: Device at device id 0x30e00 has disappeared from Name Server GPN_FT
Feb 18 18:17:09 gput49 vmunix: (FCP type) response, or its 'Port World-Wide Name' has changed.
Feb 18 18:17:09 gput49 vmunix: device id = loop id, for private loop devices
Feb 18 18:17:09 gput49 vmunix: device id = nport ID, for fabric/public-loop devices
Feb 18 18:17:09 gput49 vmunix: System won't be able to see LUNs behind this port.

Couple of questions:
1 - How do I translate the device id (device id 0x30e00 in this case) into something recognizable like a disk path or such?
2 - What does GPN_FT mean?

OS is 11.11
Server is a vpar on an RP8420
HBAs are A9784-60002 Qlogic adapters.

Hi,
First you can find the fc card in the path 3/0/6/1/0/4/0, you can type ioscan -funC fc. And you should find a device path depends on you FC card, /dev/tdx , /dev/fcdx o something. You can use the floowing command to fine n_port_id of 0x30e00 by typing:
fcmsutil /dev/tdx get remote all

0x30e00 is N_PORT ID of the device on the SAN. N_port_ids are 24-bit numbers given by SAN fabric.

There error means, there is a problem to reach the device on the SAN with this n_port_id, possibly zoning/cable or device reset problem.

You could also find it by longing into the switch and displaying the nameserver. That should so the nport IDs and ports as well and other info about the device.

However, The message says that the device disappeared for the name sever. If it didn't come back online you might not find it. But you could see what is missing if you know what is supposed to be there.
