I have an 8400 with 12 drive cages, is it possible to replace a drive enclosure online without shutting the array completely down ?
I have moved all PD's data that reside on the cage but concerned if cage is removed before new cage is inserted will the other cages still be able to process data.
If the system is correctly configured and healthy, all cages are connected thru two paths/loops which are reversed. An unrealistic example would be:
Loop1: node -> cage 1 -> cage 2 -> cage 3 -> cage 4
Loop2: node -> cage 4 -> cage 3 -> cage 2 -> cage 1
Lets say you remove cage 2, cage 1 is still connected thru Loop1 and cage 3 and 4 thru Loop2.
So replacing an empty cage (keep in mind that an empty cage is unsupported) is no problem. With you have HA cage you can also replace a cage without removing the disks first.
