SMART parameters for SAS drives behind RAID controller using perccli
Hi
I have Dell Power edge machines. I have installed perccli utility to get the details of the drives behind my PERC H710 Mini raid controller. it has Device Interface = SAS-6G.
I used following command to get smart parameters of drives.
./perccli /c0 /eall /sall show smart
CLI Version = 007.0529.0000.0000 Sep 18, 2018
Operating system = VMkernel 6.5.0
Controller = 0
Status = Failure
Description = Show Drive Smart Information Failed.Detailed Status :
===============-------------------------------------------------------------------
Drive Status ErrCd ErrMsg
-------------------------------------------------------------------
/c0/e32/s0 Failure 255 Command is supported for SATA drives only
/c0/e32/s1 Failure 255 Command is supported for SATA drives only
/c0/e32/s2 Failure 255 Command is supported for SATA drives only
/c0/e32/s3 Failure 255 Command is supported for SATA drives only
/c0/e32/s4 Failure 255 Command is supported for SATA drives only
/c0/e32/s5 Failure 255 Command is supported for SATA drives only
/c0/e32/s6 Failure 255 Command is supported for SATA drives only
/c0/e32/s7 Failure 255 Command is supported for SATA drives only
-------------------------------------------------------------------
Looks like the command works on SATA drives only.
So how do I get the SMART parameters for SAS drives ?
Would appreciate the response.
Thank you

I upgraded my perccli to latest version and it does show success for SAS drives as well.
./perccli /c0 /e32 /s0 show smart

Hi,
Unfortunately, I can't find any documentation to provide an answer to your request on the data output. Perhaps you can try other command available in PERCCLi : https://dell.to/3d378bn to check if it is able to list the information that you need.

Exactly the same question ...
Did the same as above using the newest perccli available and "show smart" command.
The output is very similar:af 00 00 0c 00 00 03 08 00 00 20 44 34 00 00 00
The rest is zeroes.
Any ideas about how to read/interpret the "show smart" output?

Hello X88,
The SMART output can be viewed in the controller BIOS and in OMSA.
As for decoding the output of the perccli command; I'm not finding anything. Maybe the community can help on this.
You may need a third party parser: https://dell.to/3jfW1PJ
I will see if I can find anything else and update if I do.

Hello X88,
It looks like the bytes are related to the Wiki Page: https://en.wikipedia.org/wiki/S.M.A.R.T.#cite_note-Intel-37

The smartctl utility on Linux can view SMART info of disks behind Megaraid controller and Dell PERC is also supported. Suppose the disk on slot 5 is a part of the virtual disk that shows as /dev/sdc in the system:
# smartctl -a -d megaraid,5 /dev/sdcFor more information, see the manual here:

Hi,
In general, I checked the version of PERCCLi 7.1020.0.0, they have just added capability SMART data for SAS drives to "show smart" command in it's release notes. Try that version if it's possible for your server.
This download is for VMWare PERCCli: https://dell.to/3vuAYM1
