We had a failure of a disk in our DS14 shelf (attached to an F810) last night. All the automatic shipping of a replacement seems to be working fine.
However, if one leaves the failed disk in the shelf while waiting for the replacement, then every few hours one gets a message like
Wed Oct 12 10:00:00 BST [raid.fdr.reminder:warning]: Failed Disk 8b.22 Shelf 1 Bay 6 [NETAPP X272_SCHT6073F10 NA06] S/N [3HZ171ZR000073420TXM] is still present in the system and should be removed.
But I am concerned that actually removing the disk with its carrier would leave the airflow through the shelf unbalanced. I have compromised by disenganging the disk from the shelf but leaving it sitting in the slot, sticking out just a little.
What do others do in in this situation? Maybe you all have dummy carriers to block vacant slots?

I think it's a common solution to release the disk and stick it out just a little so the rack door can still be closed. ;-)

If you have enough cooling in your serverroom, then don't worry about pulling a disk. NetApp engineers these things really well. Have you heard how the fans speed up when you lose one of two power supplies in a DS14 shelf?
But in any case, you should always pull a bad disk ASAP, and as you have done let it just stick out a bit, or just pull it completely and don't worry. If the environmental sensors on the shelf detect a problem, they'll speed up the fans and let you know.
