Hello! Thanks for reading.

I received an alarm from my MD3200i yesterday saying that one disk is in imminent failure state. The disk is member of a 4 disk RAID10 array. The SAN has a total of 9 disks:

4 disk RAID10 array
2 disk RAID1 array
2 hot spare disks assigned to replace any disk
1 disk not used (not assigned)

The recovery guru gives me detailed instructions to replace the disk. Basically says that i have to clic the Hardware menu, right clic the failling disk > Advanced > Fail and so on, but there is no such "Advanced" option.

That said, i googled though and came to the Dell documentation (here) which says the same thing.

What I have to do in order to replace the disk?

Thanks!
