DOS and Windows 3.1/95/98, you might not be able to
access the extra space if the existing data is stored in
an extended DOS partition. Under Windows NT, you
can use the Disk Administrator to create new
partitions in the extra space of larger drives.
Online Rebuilding feature
The online Rebuilding feature allows you to hot swap a failed
disk drive with a new one, automatically recovering all data to
the new drive with no system down time. When the Controller
Box alerts you that a drive has failed, follow these
instructions.
1. Leave the system turned on. Unlock the carrier of the disk
drive that has failed and slide it out of the 7500 Controller
Box.
NOTE 1: The 7500 will continue to save data to the
remaining disk. No current or new data is lost while
you are replacing the failed drive.
2. Remove the failed disk drive from the carrier and install a
new one according to the instructions given above.
3. Slide the carrier with the new drive into the Controller
Box and lock it.
4. The system will immediately begin mirroring the data
from the first drive to the new drive. Any data on the new
drive is overwritten with the mirror image of the first
drive.
