April 9, 20197 yr I have an issue with a couple of hard drives. Since a while ago I rebooted my server and 2 disks (one after the other) displayed the message DEVICE IS DISABLED, CONTENT EMULATED. I was sure they were damaged and I decided to remove and change them. Than I had the doubt that something was weird (two disks failing at the same time) so I just move one of them to a different slot and I run a parity check that gave 0 errors and then a SMART test on the disk and gave no errors too. On top the dashboard reports that the disk is disabled but healthy.... What shall I do? Thanks
April 9, 20197 yr Community Expert Go to Tools - Diagnostics and attach the complete diagnostics zip file to your next post.

Your ‘parity’ check was probably just a read check of all the disks that were not disabled. Having said that the vast majority of the time a disk is disabled (which results if a write to it fails) this is caused by factors external to the drive itself (e.g. cabling, Pierre, etc) and the dative is fine.
April 9, 20197 yr Community Expert Not entirely sure about your description. Since you only have one parity, it can only emulate 1 disk, and it can't really do a parity check in that situation so if you tell it to it just does a read check. You have a lot of disks and I haven't taken the time to examine SMART for each. Are any of your disks showing SMART warnings on the Dashboard? If not then rebuild. You only have one disabled disk currently. That disk looks OK so you can rebuild it to itself. Or if you have a spare you could rebuild to the spare and keep the original as backup in case there is a problem with the rebuild. To rebuild to that same disk: Stop array Unassign that disk Start array with that disk unassigned Stop array Reassign that disk Start array with that disk assigned to begin rebuild
April 9, 20197 yr Community Expert Since you rebooted after the problem occurred, we can't see it in the syslog. You should double check all disk connections, SATA and power, before attempting rebuild.
April 9, 20197 yr Author That is what I did (it took about 24 hrs) and as soon as I restarted the array here we are again. No warning on Dashboard at all (all disks are marked as healthy.)

No warning on Dashboard at all (all disks are marked as healthy.) You should provide your diagnostics zip file (obtained via Tools->Diagnostics) so we examine them to see if they give any clues (or are the last ones still valid). Edited April 9, 20197 yr by itimpi
April 9, 20197 yr Author BTW the disk is empty... so no data to rebuilt anyway. I just would like to understand if is ok to use it and how can I have it back to the array. The diagnostic I have is here... monstruo-diagnostics-20190409-1649.zip
April 9, 20197 yr Community Expert Disks 7 and 10 also showing some warning signs, but no media errors for now, just keep an eye on them.

So you will have to replace it with another and rebuild the empty disk, or you can remove it with New Config and rebuild parity.
April 11, 20197 yr Author Ok... I followed the advices and I removed the faulty drive and after I rebuilt the parity... All fine for like 30 minutes then had a new problem with another disk (this time disk nr. 6 has write errors...). It is the 3rd disk in a row!!!! What is happening?

April 11, 20197 yr Author Here it is... monstruo-diagnostics-20190411-1435.zip I checked all the connections and they seems to be fine....
April 11, 20197 yr Community Expert Diags are after rebooting, so we can't see what happened, but disk looks fine, suggest replacing/swapping cables/backplane slot to rule them out and rebuild to the same disk (or to a new one if you to play it safer)
April 11, 20197 yr Author Thanks for the answer... What you think is happening? I have the same issue over and over again. The cables are brand new and the case is not that old too but the problem more and more frequent.... Really do not know what to think
April 11, 20197 yr Community Expert 2 minutes ago, gideva said: What you think is happening? If it happens again grab the diags before rebooting, without them no way to tell, in the meantime you can try and rule out some things, does it always happen to disks on the same controller, on the same miniSAS cable, etc, sometimes these kind of problems can only be fixed by swapping some hardware, like cables, HBAs, PSU, etc.
April 11, 20197 yr Author I will grab the diags before rebooting for sure (lesson learned!). The thing seems to be random (different cables, backplane, slot etc...) and I already tried to . disconnect all the cables and plug them back again. We will see. Thank you very much for your help. Really appreciate
April 11, 20197 yr Author Sorry for the stupid question... How do I rebuilt on the same disk? I want to do it the right way...

April 21, 20197 yr Author It happened again... Just got back from a quick break and I found that another disk is in the same situation... I grabbed the diagnostic before reeboting this time. Hope this help to find finally a solution to this problem once forever... monstruo-diagnostics-20190421-1617.zip
