Today I received one of the ZeusRAM that I ordered, both brand new. I was
struggling to find SAS SSD drives that were available in my price range as I
desperately need to add a ZIL.
I decided to order ZeusRAM since they had one in stock and figured I'll add it
while waiting for the other one as they are really should not be prone to
failure based on design. I have not used them and would normally just prefer to
use regular SSD drives.
Slotted ZeusRAM in and it began to rapidly blink the same as the disks that are
currently in the pool on that backplain. Running the command format would never
return with a list of disks. I left it for about 15 min and pulled it since it
says on the disk that it can take up to 10 min for the caps. I could see there
is an amber and green LED on the drive itself blinking, even when removed.
I slotted it back in and the disk was then available. After a few min the fault
light cam on and the disk was unavailable due to the following:
Fault class : fault.io.disk.predictive-failure
Affects :
dev:///:devid=id1,sd@n5000a720300b3d57//pci@0,0/pci8086,340e@7/pci1000,3040@0/iport@f0/disk@w5000a72a300b3d57,0
faulted and taken out of service
FRU : "Slot 09"
(hc://:product-id=LSI-SAS2X36:server-id=:chassis-id=50030480178cf57f:serial=STM000****:part=STEC-ZeusRAM:revision=C025/ses-enclosure=1/bay=8/disk=0)
faulty
Description : SMART health-monitoring firmware reported that a disk
failure is imminent.
I cleared the fault and the drive was then usable again for a few min same
thing happened. Eventually the amber light on the disk itself (not the
enclosure disk light) no longer blinked and the disks was online for quite some
time before the alert above reappeared.

Is there anything special that should be done for ZeusRAM in sd.conf? Its a
node install and both nodes can see all the drives. I don't see any smart
errors listed, but running fmadm it will show the disk as faulty due to
predictive failure.
