How to determine why FC-adapter got disabled

[jenoptik]

Hi there,

How can I determine the cause of a disabled fc-adapter?

This night the adapter has changed its state to disabled, why?

What errors/failures can occur if i enable the adapter again? 

Which log is the right one?

Thx 4 any reply

Problem solved.

Checked EMS Log, Shelf_ESH Log

Look for fci and esh entries:

Wed Sep 2 22:07:15 CEST [n001020: fci.link.error:error]: Could not recover link on Fibre Channel adapter 0b after 30 seconds. Offlining the adapter

<esh_word_error_1

diskID="[IN] port"

channels="PARTNER/0b"

shelfID="1"

element="ESH A "

bay=" "

reason="reports invalid word error"/>

No connections between fc adapters.

possible reasons:

failed esh modul

failed sfp transceivers

Reason: failed sfp transceiver

After replacement of sfp transceiver the resync has started. Resync completed. Everythin is fine.
