Updated from 10.6.2 to 10.6.3. After reboot, the array is offline and all data and parity disks show as "missing"! The disks do show up under unassigned devices, but when I try to reassign them to the array in their previous positions, they show as "wrong". Dell R720 with 3x 4TB data, 1x 4TB parity in the array.

Take a screenshot of the old disk assignments then go to tools and do a new config, re-assign all the disks to their original slots, check "parity is already valid" and start the array.

I followed your advice and my array is back on-line, thank you! Still curious as to why my configuration did not survive the update/reboot..

02:00.0 Serial Attached SCSI controller [0107]: Broadcom / LSI SAS2308 PCI-Express Fusion-MPT SAS-2 [1000:0087] (rev 01)
	DeviceName: Integrated RAID                         

RAID controllers are NOT recommended with Unraid.

I'm not sure what to do with this information. Yes, the R720 has a RAID controller, which I flashed to IT mode for use with Unraid as per numerous instructions..

SAS devices were displaying the long name and are now using the short, though strange this happening after updating from v6.10.2 to v6.10.3, are you sure you didn't update from v6.9.2?

Actually, I updated from 6.9.2 to 6.10.2 just a few days ago, and then from 6.10.2 to 6.10.3 when prompted last night. I didn't notice any differences (in the Unraid UI at least) in how the disks are identified. What are the SAS long and short names to which you refer?

And nothing changed after updating to 6.10.2 correct?

Long name includes the world wide name:

 

HUS724040ALS640_PCK5U0LX_35000cca05cb3a924

 

Short name omits that:

 

HUS724040ALS640_PCK5U0LX

 

Note that there's also an option in "Settings -> Display Settings -> Display world-wide-name in device ID" that also affects that, but I assume you didn't change anything.

Interesting.. Yes I recall seeing the long names before, and the fact that my "Historical Devices" list shows long names would seem to back this up. However I can't tell you if the change to short names occurred after the 6.9.2 to 6.10.2 update, if that's what you're asking. I certainly didn't change it in Settings.

Just now, DAC said:

if the change to short names occurred after the 6.9.2 to 6.10.2 update

I would expect it to change after this, but that could only be if you didn't use the array after updating to 6.10.2, since you'd have the same problem you posted about now.

Ok, makes sense. So the system came back up with short names after rebooting into 6.10.3, and that caused it to lose track of my disks. Don't know why it decided to change disk names, if that was part of an update I imagine it would have broken the config for a lot of users! My config is rebuilt now and after rebooting, it survived. Thanks for your help!
