HBA failed

Hi

I have a Solaris 8 server attached to a EMC Symmetrix 8430 array. Having 2 HBAs with Powerpath.

root@CSCUSDMYSPDB1 # powermt display
Symmetrix logical device count=21
CLARiiON logical device count=0

This server is located remotely so I have to rely on the local hands and legs guy to check.

He said both HBAs and SAN ports connecting to the HBAs are green and blinking continously.

What could be the real problem? Server has been up for 499 days. I don't see any scsi errors on the messages file.

But in format, I notice 1 drive is down.
