Creating A Raid 1 Array - Promise Technology SuperTrak SX6000 User Manual

SuperTrak SX6000™ User Manual
Setting the Gigabyte Boundary
For RAID 0 arrays, SuperTrak SX6000 sets the "Gigabyte Boundary" to
"OFF".

Creating a RAID 1 Array

In the "Define Array Definition Menu" section, use the [Spacebar] to cycle through array
types and select "RAID 1" for RAID Level. You will be creating two drives or two pairs of
striped drives (4 or 6 drives total) with identical data on them. The capacity of the array
will be half that of the total number of mirrored drives within the array. No stripe block
size option is available when mirroring 2 drives. In a 4-drive RAID 0+1 or 6 drive array,
you can set the stripe size for the two pairs of striped drives.
If you are creating a Mirroring array containing two drives only, you will use either two
brand new drives, or one drive that contains existing data and a second drive that you
wish to mirror data. There is an additional window that will appear in order to create
such an array.
Creating a Mirroring Array with Two New Drives
As described above, if you select a mirroring array and wish to use two new
assigned drives, follow the directions here. Under the "Drive Assignments"
section, assign both new drives to the array and save the information with
[Ctrl-Y]. The following window will appear in order to create the array. Confirm
"N" or "Create Only" to the message shown in order to proceed.
Do you want the disk image to be
duplicated to another? (Yes/No)
Y - Create and Duplicate
N - Create Only
Figure 9 Two-Drive Mirroring Dialogue Window
Once the process is complete, you will be returned to the Define Array Menu
where the array will be shown as defined.
NOTE: you may choose to attach an unassigned third drive to SuperTrak
SX6000 to act as a "hot spare" replacement (see Page 25).
Creating a Mirroring Array with an Existing Data Drive
SuperBuild will create a mirrored array using an existing drive with data. In
the "Drive Assignments" section, you must assign the existing data drive and
another drive of the same or larger capacity to the Mirroring array. Press
[Ctrl-Y]. Create the array by confirming "Y" or "Create and Duplicate" to the
message window that appears (same message as in Figure 9 above).
You will be prompted to select the Source drive from the two available drives.
[Arrow] down to the drive that has existing data to be mirrored and press
[Enter] to select at the message window below:
