Probably a failing drive - use fmdump -eV for the scsi errors,
the dev links in /dev/rdsk/c2t3d0 gives you the device path to look
for. Use iostat -Exn to get the Smart Errors for that drive,
/var/adm/messages probably has some details, fmadm faulty
messages will convince your support (if you have one) to replace
the drive.
