Thank you. I am sending it back to where we purchased it from. I thought these were no longer avail, but the distributor still listed them and had in stock.
I was hesitant to purchase, but I am in desperate need for a ZIL. ________________________________ From: Richard Elling <richard.ell...@richardelling.com> Sent: Monday, April 10, 2017 4:15:32 PM To: Machine Man Cc: omnios-discuss@lists.omniti.com Subject: Re: [OmniOS-discuss] ZeusRAM - predictive failure On Apr 10, 2017, at 1:00 PM, Machine Man <gearbo...@outlook.com<mailto:gearbo...@outlook.com>> wrote: 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 This occurs when the drive responds to an I/O and indicates a predictive failure or the periodic query for drives sees a predicted failure. It is the drive telling the OS that the drive thinks it will fail. There is nothing you can do on the OS to “fix” this. It is possible that HGST (nee STEC) can help with further diagnosis using the vendor-specific log pages. Several years ago, STEC helped us with root cause of failing ultracapacitor in a drive. AFAIK, there is no publicly available decoder for those log pages. — richard 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. === START OF INFORMATION SECTION === Vendor: STEC Product: ZeusRAM Revision: C025 Compliance: SPC-4 User Capacity: 8,000,000,000 bytes [8.00 GB] Logical block size: 512 bytes Rotation Rate: Solid State Device Form Factor: 3.5 inches Logical Unit id: 0x5000a720300b3d57 Serial number: STM000****** Device type: disk Transport protocol: SAS (SPL-3) Local Time is: Mon Apr 10 19:17:23 2017 UTC SMART support is: Available - device has SMART capability.

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.
