Hi,
is that a FC card on the given hw path? It could be anything in the SAN. Check logs on your sanswitch, disk array....

This message means that your server lost connection with the device it was communicating with.

Also make sure that it is not any old message in the dmesg. Compare it with actual /var/adm/syslog/syslog.log

Hi ,

check "state" column in this command for any disk showing "NO_HW"
1)ioscan -funC disk

Use fcmsutil /dev/fcd0 ( or fcd1 / 2 etc depending on you rfc card ) ,you should see "Driver state = ONLINE".If you have a NO_HW from command 1) above , match the HW path of the NO_HW disk to the fcmsutil of the fiber card to trace problem from SAN side if any.

Is that a 2-port FC card you are having problems with? HW path 2/0/10/1/0/4/1 and 2/0/10/1/0/4/0 is indicating, that it should be the same slot on your server.

try using:
# ioscan -fnN -H 2/0/10/1/0/4/1
#ioscan -fnN -H 2/0/10/1/0/4/0

or legacy output:
#ioscan -fn -H 2/0/10/1/0/4/1
#ioscan -fn -H 2/0/10/1/0/4/1

As was suggested above, try checking the fcmsutil /dev/fc..X output, depending on which fc card are you using.

#ioscan -kfnC fc to see the DSF's of your fc cards.
