I would default the switch and/or remove all FCOE config. The NOS platform has not supported FCOE for several years.

I am not sure of the best procedure to default the switch? I have copied default-config to startup-config and it still does it...

how do I remove all FCOE config?

Can you give me a step by step to default the switch?

Also receiving the error on boot up

[0] ERROR IRQ reflected, error-int=15, guest=p1-linux core 0 base 0x238f32421 window 0xb2be0e time 0x239a5e298 count 45590 printed 1

and it counts all the way up to 64

All the lights on the front of the devices stay amber lit once booted.

"copy default start" and a reload should remove all configs from the device if it is a stand alone device.

Regarding the boot error, I see several issues reported with this error that were fixed in the newer releases. Are you running an old version of NOS? You can try upgrading to the latest version.

FCOE stopped being supported as of NOS 7.3, so I would try removing the FCOE license:

"license remove licStr FCOE_BASE"

* You may or may not need to reload after this, if you still see the ports as all FCOE I would reload after removing the license.

Regarding Standalone mode, sorry if I confused you. Way back in NOS 2.x we had an actual mode "Stand Alone", however in the 7.x versions there is only "Logical Chassis" mode. What I meant by standalone was; Is this device in a fabric with other devices, or in a fabric of one? I see from your output that this device does not have any other VCS peers, therefore it is own Principal switch and managing its own config.

Regarding the Core/FFDC files, these are likely historical. You can view the dates via:

"show support"

If they are all old you can clear them with:

"clear support"

If the device is constantly generating them you would need to open a case with TAC to investigate.
