What is FCP Array Interface?
Is it a hardware or a virtual unit?
In above example, I think the fibre link is fine. Why the FCP Array Interface is NO_HW?

hi,

grep EMS /var/adm/syslog/syslog.log

ioscan -fnC fc

fcmsutil /dev/[fcd|td]0-last

check if all HBA are online

check the SAN.

hi,

check this link :

sorry

Event 39.

if you can try to enable / disable HBA but if its a production box, you should decide if its possible or not.

check the SAN for changes.
