Ever since I added several SAS drives to my array, when I reboot the server I have to fix the config, if it will let me.

 

I have attached what I run into when I boot, and what I have after I reassign the drives. It seems it is fine, except it has to rebuild the primary parity every time.

 

(Please ignore the DataTraveler. I forgot to unplug it.)

 

My setup consists of the following:

3 SAS, 2 SATA drives and a cache SSD

A Supermicro BPN-SAS-826EL1 SAS expander backplane in another case for drives.

A Dell Perc H310 flashed to IT firmware

Dell R710 II

One thing I do not have a screenshot of is that after a few minutes of rebuilding, it disables disk 3 (red x). I am not sure why, but all the drives in this setup are known good drives.

Probably something is changing in the SAS disks identification between reboots, when you can reboot and post new diags.

You can also try the Dynamix SCSI devices plugin, see here

You are right with the SAS drives having different identifiers each time.

 

I did install the SCSI plugin and it seems to have resolved the issue. One suggestion for that plugin would be to add the SN to the identifier. It would give you some indication of what drive it is referring to that way.

 

Hope this thread helps someone else with this issue.

 

Thanks a ton.
