is no longer available. Without this feature enabled, FastTrak100 will NOT permit the
use of a replacement drive that is slightly smaller than the remaining working drive.
For the Gigabyte Boundary feature to work, the Gigabyte Boundary feature must be
set to "ON" when the original mirrored array is created. When enabled, the Gigabyte
Boundary feature rounds the drive capacity of both drives to the common w hole GB
drive size. For example, with the Gigabyte Boundary feature enabled, the remaining
working drive can be 20.5 GB and the replacement drive can be 20.3, since both are
rounded down to 20GB. This permits the smaller drive to be used. Please note that
users will lose a small amount of available storage capacity from both drives in order
to arrive at a common drive size.
NOTE: The Gigabyte Boundary feature is automatically disabled when creating a
mirrored array (RAID 1) from an existing drive (versus using two brand new drives).
This protects the existing drive's partition table in order to maintain data integrity.
Assigning Drive(s) to Array
1. Under the [ Drive Assignments ] section, highlight a drive using the [ ] or [ ]
keys.
2. With the [Space] bar key, change the Assignable option to "Y" to add the
drive to the disk array.
3. Press <Ctrl-Y> to save the disk array information. Depending on the array
type selected, the following scenarios will take place:
a) If choosing a Striping, Spanning, or Mirroring/Striping array, the initial
Define Array Menu screen will appear with the arrays defined. From
there you may ESC to exit and return to the Main Menu of FastBuild.
b) If you selected a Mirroring array for two drives, there is an additional
window that appears as described in order to create the array. To do
this you will use either two brand new drives, or one drive that
contains existing data that you wish to mirror.
Creating A Mirrored Array Using New Drives
As described in the Drive Assignments Option section above, if you selected a
mirroring array and wish to use two new assigned drives, follow the directions here.
1. After assigning new drives to a Mirroring array and saving the information
with <Ctrl-Y>, the window below will appear.
Do you want the disk image to be duplicated to another? (Yes/No)
Y - Create and Duplicate
N - Create Only
2. Press "N" for the Create Only option.
