Well, it is likely that this disk has failed but can't tell for sure. If the array is still functional, with the disk down, then you could likely pull it and replace it. Whether it will rebuild depends on whether a spare has already taken over for this vdisk. If one has, then this disk will likely just be available but unassigned. In that case, it might be worth while to mark it as a spare so it can function for a future failure. As always, if you have support on the array, log a support case and have support walk you through the whole event. You'd need to do that anyway if you were getting a replacement drive under support. Assuming you don't have support then you'll need to source your own replacement drive and kind of wing it.
So that we have more information, please consider using putty to CLI into the array. Then, paste the outputs of the following commands:
- show disks
- show vdisks
- show spares
Thanks
