I managed to brick one of the controllers in my FAS2220 HA pair running 8.1.2 (7 Mode).
It originally had 4 disks assigned and was sat there in an active/active config with only the root vol across 3 disks with one as a spare. I had to give up the DS2246 shelf attached to it for U requirements and basically did a p*ss poor job of decomissioning it. Turns out 2 of the root vol disks were located there, the shelf is long gone now. I have two disks spare (now unowned) on the first controller to assign to the bricked controller but booting into OnTAP just isn't going to happen without netboot I fear.
Is there anywhere I can get the boot image from? I don't have a subscription contract any more as this unit was decommed a while back, gutted.
PANIC: raid: there are no data or parity disks in SK process rc on release
Well, the error is "no data or parity disk". Of course it is possible that disk labels were upgraded to newer version in which case one indeed needs newer (Data) ONTAP. But that's just speculation without seeing full boot log. But if the problem is simply that root aggregate had been lost, then no netboot is needed.
