Missing autoRAID disk
It appears that one of the disks was failed but when reseated came good again. But somewhere in the process, the autoRAID thinks it has got a new disk.
Is there any way to get rid of this phantom disk.
All I can think of is arraycfg -D but the missing disk does not have a slot number so I can't refer to it at all. The autoRAID is now in a degraded state because it thinks a 13th disk has data on it even though this is not the case.

Re: Missing autoRAID disk
My best guess is that that a rebuild was interrupted or that you have more than 1 bad disk although old 12H firmware could be buggy OR you disn't install the array software updates required by the firmware.
You may need to run arrayrecover but your first task should be to make sure you have good backups -- so you won't need them.

Re: Missing autoRAID disk
Note that the array is reported missing "Data Unavailable" and because of the way the AutoRAID stores data this is almost certainly not restricted to a single LUN. I trust you have backups. In my experience, it was alway dumb to reseat one of these disk modules, yes, they may spin up again and come ready but they are an accident waiting to happen. I always replaced the drive at that point.
I've only used 4 of the older Model 12's but in my experience they were not nearly as reliable as their 12H cousins. Other than routine disk module/controller battery replacements. I've never had a moments trouble with 12H's and that represents well over 200 array-years service and in that time have never lost a single bit of data.

Re: Missing autoRAID disk
We did a power off and on of the autoRAID and when it restarted it forgot about the phantom disk so I guess the desired result has been achieved and the old master reset fixes the problem yet again.
