Chapter 4 HP NetRAID Express Tools • 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 81
