Swapping hard disks
If you’re using RAID 5 + spare or RAID 10, you can move the hard disks from one slot
to another whether or no t the storage system is running. However , if you do this
when the storage system is running, you can swap only two disks, and you must
restar
t the system after you swap the disks. If you swap the disks when the storage
system
is not running , you can swap all four disks, and the system will function as it
previously did when you restart it.
Note: For RAID 5 + spare , if you swap the disks when the storage system is
running,
one o f the swapped disks must be the spare.
For RAID 10, the swapped disks must be in dif f erent pairs. For example, you can
swap
disks 1 and 3 or disks 2 and 4, but no t disks 1 and 2, as those are members
of the same pair .
If t he storage system is running when you swap the disks, the Disk Change
Notification page displays (as shown in the preceding section). Click Shut Down
and then restart the system.
For all other disk configurations (linear , RAID 0, RAID 1, and RAID 5), you can swap
the
hard disks only when the storage system is powered of f, and you can swap all
four
disks.
