One of the disks in group 0 (EID:Slot 252:4, DiskID 12) is starting to fail it's smart tests:
1 Raw_Read_Error_Rate 0x002f 200 200 051 Pre-fail Always - 1837
200 Multi_Zone_Error_Rate 0x0008 200 200 000 Old_age Offline - 57
but I can't find any documentation how to remove disks from a disk group.
Do I have to
storcli /c0/e252/s4 set offline
or rather
storcli /c0/e252/s4 spindown
or both? What's the difference between "spindown" and "offline"? What about
storcli /c0/s4 set missing
What does that do? What does "missing" mean?
And how about the rebuild? Does that start automatically?
If not, then I guess the "start rebuild" command is my friend but why do I have to specify a single disk for that? It would make much more sense to specify the disk group or volume to rebuild, no?
