Cannot access disk S.M.A.R.T data

[Simon_H]

I've just upgraded a whitebox lab server from 5.0U1 to 5.1U1 today with the hope of accessing S.M.A.R.T. data for some directly attached SSDs (no RAID card). Unfortunately all I get is:

# esxcli storage core device smart get -d "t10.ATA_____OCZ2DVERTEX4_____________________________OCZ2D<...etc...>"

Error getting Smart Parameters: CANNOT open device

I also tried running /sbin/smartd as per KB 2040405 but didn't see anything in syslog.log.

I realise this isn't a server on the offical HCL but I was optimistic the data would still be passed through - might be a BIOS/controller issue I suppose. Any ideas?

PS. mobo is ASRock Z77 Extreme (with Intel i7-3770)

Can you run

/usr/lib/vmware/vm-support/bin/smartinfo.sh

and tell us the output.

Sure - the devices show up (as they do with esxcli storage core device list) but don't seem to be able to be accessed:

~ # /usr/lib/vmware/vm-support/bin/smartinfo.sh

I have used a vendor's utility (for Crucial M4) in the past to update the disk and IIRC it had the S.M.A.R.T. data visible suggesting it's coming through the controller/BIOS - that might be the next thing to check though I suppose (when I can power down the host again). I thought I'd check here first to see whether others have had any success though, before wasting too much time on it, as it's a very new feature.

Very true.

Does this look like the enclosure??

Sorry... its not..

Let me check up with my server having a SSD RAID configurable setup..

Since this question is still not answered after a year, I am trying to add my solution when I had the same problem as you.

I have a AsRock970 Extreme4 motherboard for my ESXi box. Check the BIOS setting for storage. You will probably find a setting where you can enable or disable SMART.

I had the same output as you had for the smartinfo.sh script until I changed the BIOS settings.

I recall now that I turned this settings off in the BIOS due to all the warnings of exceeded temperature messages - when the smartd wasn't interpreting the values correctly for the WDC drives.
