•
Initiator ID: Changes the Initiator ID assumed by the HP NetRAID
controller (adapter) at system boot-up. The default setting is SCSI ID 7.
Logical Drive
To perform a logical drive procedure, choose Logical Drive from the Objects
menu. The logical drive options are:
•
Initialize: Initializes the selected logical drive. See "Initializing Logical
Drives" in this chapter for more information.
•
Check Consistency: Ensures that parity or mirroring is correct for the
selected drives. Click on the logical drive to be checked. RAID levels 3, 5,
30, and 50 use an extra drive to store parity data blocks; parity is checked
between these parity data blocks and the selected drives. RAID levels 1
and 10 use duplicate data drives (mirroring); the duplicate data is verified.
Check Consistency should be run if the system shuts down irregularly,
such as if the system hangs or suffers a power failure. It is also
recommended that you run consistency checks every two to four weeks to
ensure that bad blocks on the disk drive are mapped out. Check
Consistency always remedies inconsistencies. Check Consistency will fail
only if the firmware could not complete parity and data writes due to a
power-failure or a system hang, or if the logical drive degraded or failed
when the physical drives went offline.
•
Properties: Displays the selected logical drive properties of RAID level,
size of the logical disk, stripe size, Write Policy, Read Policy, Cache
Policy, Virtual Sizing, power-on rights, number of stripes, and state.
Physical Drive
Selecting Physical Drive opens the Physical Drive Selection menu. The hard disk
drives in the HP NetServer are listed. Hot key functions are displayed at the
bottom of the window. To access drive information, press F2, and view logical
drives by pressing F3. Use the arrow keys to move the cursor to the desired
device, and press Enter to display the following options.
•
Rebuild: Rebuilds the selected disk drive.
•
Format: Low-level formats the selected disk drive. Choose the Format
option only if:
◊ The disk drive was not low-level formatted at the factory
◊ There is an excessive number of media errors detected on the disk drive
