Qlogic OFFLINE / ONLINE - Storage

I have a Sun Fire v480 server that just started spitting out NOTICEs
about Qlogic qlc(0) Loop going OFFLINE then immediately back ONLINE.
It's doing it about every couple hours.

I realize I may have a faulty Gbic somewhere, but how can I verify if
qlc(0) is the internal controllers for the dual SCSI disks or if it's
the Qlogic IPS2200 add-in card.

OS: Solaris 10 (11/06)
Kernel: 125100-07

luxadm -e port

/devices/pci@9,600000/SUNW,qlc@2/fp@0,0:devctl CONNECTED
/devices/pci@8,600000/pci@1/SUNW,qlc@4/fp@0,0:devctl NOT CONNECTED
/devices/pci@8,600000/pci@1/SUNW,qlc@5/fp@0,0:devctl CONNECTED

Is qlc(0) really /devices/pci@9,600000/SUNW,qlc@2/fp.... ? That
would mean the internal controller would be going bad in the v480,
right?

Thanks, happy holidays.

The qlogic gbic IS the problem, change to other gbic, IBM make are good.
