Take the appropriate action:
• To scan the storage system again and update the information on the page: Click “Scan”.
• To re-install the same disk or install a new disk: Click “Shut Down”. After the storage system
shuts down, install the disk and then restart the system.
Note: If you are re-installing multiple disks, be sure to re-install them in the
opposite order than you removed them.
• To return to the web interface and continue to operate in a degraded mode: Click “Ignore”.
Responding to RAID failure
When disk removal/failure causes the entire RAID to fail, the Disk Change Notification page
appears when you access the Manager or refresh the browser window (Figure A-4).
Take the appropriate action:
• Scan the storage system again and update the information on the page: Click “Scan”.
• To re-install the same disk: Click “Shut Down”. After the storage system shuts down, re-
install the same disk and then restart the system.
Note: If you removed multiple disks, be sure to re-install them in the opposite
order than you removed them.
• To reconfigure the storage system using the available disks: Click “Reconfigure Disks” and
complete the system setup pages.
Caution: Reconfiguring the storage system deletes all user information and all
data on all the disks.
A.3 Swapping Hard Disks
If you are using RAID 5 + spare or RAID 10, you can move the hard disks from one slot to
another whether or not 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 restart 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.
Notes:
• For RAID 5 + spare, if you swap the disks when the storage system is
running, one of the swapped disks must be the spare. For RAID 10, the
swapped disks must be in different pairs. For example, you can swap disks 1
and 3 or disks 2 and 4, but not disks 1 and 2, as those are members of the
same pair.
•
If the storage system is running when you swap the disks, the Disk Change
Notification page appears (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 off, and
you can swap all four disks.
