SuperTrak66™ User's Manual
Chapter 3
NOTE: Since spanning uses the full capacity of each assigned drive, different
capacity drives may be used without adversely a ffecting the performance of the
array. No other RAID benefits are provided (see Chapter 6).
Assigning Drives to a Spanning Array
Under the [ Drive Assignments ] section, highlight a drive, and, with the [Space] bar,
change the Assignable option to "Y" to add the drive to the Spanning array. Press
<Ctrl-Y> to save the disk array information. The initial Define Array Menu screen
will appear after you have pressed [Ctrl-Y]. You will see the array defined. You may
press the [ESC] key to exit and return to the Main Menu of SuperBuild.
"Hot" Spare Drives
Any extra drive that is not assigned to a fault tolerant disk array (RAID 1, 3, or 5)
will be recognized as a Spare Drive. In Figure 10 on page 23, the fourth drive shown
is unassigned and would be used as a hot spare for this RAID 3 array. Such a drive
is automatically added to an array once a disk member of the array has been
detected as "failed." To restore fault tolerance as quickly as possible,
SuperTrak66 begins to perform an automatic data rebuild on the "spare" drive in
the background without the need to restart the system. At a later time, the failed
drive can be physically removed and an extra drive added in its place to function as
the "spare" drive.
Setting a Disk Array As Bootable
You may select which defined array will be used as the bootable array from the
[ Define Array ] menu (Item [3] in the Main Menu). Highlight the desired array and
press the [Space] bar key. The system will now recognize this as the first array
and an * asterisk will appear next to the array number indicating it as bootable (see
Figure 13 below).
NOTE: Your PC or server must be configured to use SuperTrak66 as the bootable
controller. The system will then use the bootable array as the (fixed) boot C: drive.
