Using the ArrayConfig Program

Using Custom Setup To create an array using Custom Setup, you will need to do

 

the following:

 

 

 

 

NOTE

You can also perform most of these advanced options with the HP RAID

 

Device Manager once you’ve completed the installation and the HP

 

RAID Device Manager has been installed. Refer to the HP RAID Device

 

Manager’s online Help for more information on using this utility.

 

1

Insert the ArrayConfig diskette in drive A and reboot your

 

 

 

computer. Wait until ArrayConfig starts automatically.

 

2

Read the text that appears on the initial ArrayConfig screens. Press

 

 

any key to view the next screen, or press

to return to the

 

 

previous screen.

 

 

 

3

When you see the Setup Type Selection Menu, select Custom Setup.

 

 

Then wait while ArrayConfig scans your system for information

 

 

about your host adapter and SCSI devices.

 

 

4

When the Main Menu appears, select Disk Array Operations.

 

5

Select Create New Array from the Disk Array Operations menu.

 

6

Type a name for the array and press

. The name can be up

 

 

to 15 characters long and can include spaces and any other printable

 

 

characters.

 

 

 

7

Select an array type from the following options:

 

 

• RAID 0: Data is striped across the disks in a RAID 0 array,

 

 

allowing for faster data input and output than a single disk.

 

 

RAID 0 arrays do not store redundant data; if any disk in the array

 

 

fails, all data is lost.

 

 

 

 

• RAID 1: Data is mirrored on one pair of disks. If one disk fails, data

 

 

is still safe. The actual usable data capacity of the array equals

 

 

half the available disk space.

 

 

8

Type the number of drives you want in the array, not including spare

 

 

drives, and press

. The number of drives available for

 

 

assignment is listed on the screen. (You will not be prompted for the

number of drives if you are creating a RAID 1 array, because RAID 1 arrays have two drives by definition.)
