[OmniOS-discuss] Bad ZeusRAM? How to tell if another component is causing issues?

[wuffers]

I'm at home just looking into the health of our SAN and came across a bunch
of errors on the Stec ZeusRAM (in a mirrored log configuration):

# iostat -En

        (end detector)

from format:

57. c12t5000A72B300780FFd0 <STEC-ZeusRAM-C018-7.45GB>
          /pci at 0,0/pci8086,3c08 at 3/pci1000,3030 at 0/iport at f
/disk at w5000a72b300780ff,0

Both fmdump and dmesg has these errors repeating over and over. Everything
seems to point to the drive. I suppose I would have to physically move the
drive to eliminate cable, backplane or controller issues. Is there another
way to tell just by these error logs or is the physical test the way to go?

Are logs enough to justify an RMA?
