HP Online Array Configuration Utility for NetWare 18
Creating a new array and logical drive
1.
Open CPQONLIN and select the controller that you want to configure.
The Logical Configuration View panel appears.
2.
Press the
Enter
key.
The highlight moves to the Controller Options panel.
3.
Highlight the
Create New Array
option, and then press the
Enter
key.
The screen displays three panels (Create Array, Physical Drives, and New Array), and the highlight
moves to the Create Array panel.
4.
Highlight the
Assign Drive
option, and then press the
Enter
key.
The highlight moves to the Physical Drives panel.
5.
Highlight a drive that you want to be part of the array, and then press the
Enter
key.
The New Array panel displays the added drive, and the highlight returns to the Create Array panel.
6.
Repeat steps 4 and 5 until you have finished building the array.
o
For the most efficient use of drive space, select physical drives of comparable capacity.
o
For optimum system performance, select physical drives that are connected to different ports on the
controller.
o
If you intend to create a RAID 5 configuration, keep the risk of logical drive failure low by assigning
no more than 14 physical drives to the array.
o
Do not select any physical drives that you want to be spare drives. Spare drives are created in a
separate procedure ("
Adding spare drives
" on page
18
).
7.
Highlight the
Accept Changes
menu option, and then press the
Enter
key.
The Create New Logical Drive panel appears.
8.
Select the RAID level that you want the logical drive to use, and then press the
Enter
key.
9.
Select the stripe size that you want the logical drive to use, and then press the
Enter
key.
10.
Enter the capacity that you want the logical drive to have, and then press the
Enter
key.
11.
Press the
Esc
key to save the settings and return to the Logical Configuration View panel.
12.
To make new logical drives available for data storage, format them using the instructions given in the
operating system documentation.
Adding spare drives
Assigning one or more online spare drives to an array enables you to postpone replacement of faulty drives.
However, it does not increase the fault-tolerance level of any logical drives in the array. For example, a
logical drive in a RAID 5 configuration suffers irretrievable data loss if two of its physical drives are
simultaneously in a failed state, regardless of the number of spare drives assigned to the array.
Any drive that you want to use as a spare must meet the following criteria:
•
It must be an unassigned drive or a spare for another array.
•
It must be of the same type as existing drives in the array (for example, SATA or SAS).
•
It must have a capacity no less than that of the smallest drive in the array.
To add a spare drive to an array:
