DSM on Hyper-V Cannot Read HDD S.M.A.R.T and Temperature

Recommended Posts

Hello all,

 

       Having my DSM running on a HP microserver gen8 virtualized using Hyper-V. However it seems that VMs cannot read HDD S.M.A.R.T and temperature info. How do I solve it? Thanks for any suggestions.

Are you using AHCI or B120i for the disk controller?

Virtualized....

 

DSM is running in a VM, with the disks passed through to the VM, right? 

 

If so, then this is 100% normal.  HyperV does NOT pass on SMART data to the VM.  It's one of the biggest issues with HyperV that I have (that and not being able to increase resources "live").

Thank you for the reply! How about Exsi?

Yes, I believe so.  However, you need to use "RDM" (Raw Device Mapping) to do so. 

I'm a hyperV guy, so I'm not really sure how to do this.

I just checked on Hyper-V 2016 and this feature is not in there either, however they did include the hot adding of NICs and RAM.

iLo could flag you with some warning and failure info, but you would need a local mail server.
