it looks like that the specific path is not (longer) available.
Maybe your storage admin has removed the mapping for this volume or the zoning for this path has been removed.

An lspath and lscfg -vl hdisk10 would be helpfull.

Looking at the error, it seems SAN problem (as Xray said).
Also, I am seeing you have the physical card connected to the system. ( So NPIV or VSCSI is ruled out and so is looking at VIO for the same).

Run the below command
lspath -l hdisk10 -s available -F"connection:parent:path_status:status"

This will give you exactly which connection at storage (fibre adapter - FA) failed.
One connection from your (fscsi3) port is going to Fabric and it has two connections (from Fabric to Storage. So one from fabric to Storage is down).

Also, what storage you have?

Send the output of
lsdev -Ccdisk

Hope this helps!

The Mapping normaly points to the MAC-adress of your FC-Adapter.

Use the following command to get the MAC-adress:
lscfg -vl fcs3 | grep -i "Network Address"

find the below Network Address
