Logical Drive Menu
The Logical Drive menu options are described below.
•
Initialize: Initializes one or more logical drives. To initialize one or more
drives, first select the logical drive(s) to be initialized, then choose
Initialize.
After configuration, a logical drive must be initialized before it can be
used. This option initializes the logical drives by writing zeros to the data
fields and generating corresponding parity fields on drives with RAID
levels 3, 5, 10, 30, or 50.
CAUTION
HP NetRAID Assistant allows you to initialize a drive at any
time. Make sure that the drive being initialized does not hold
active data. All data will be lost when you choose the
Initialize menu selection.
•
Check Consistency: Ensures that parity or mirroring is correct for the
selected drives. Click on the drive to be checked (LD0-LD7). 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 after 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
because the logical drive degraded or failed when a physical drive went
offline.
You can use a Windows NT Monitor Service for HP NetRAID Series
adapters to schedule and perform Consistency Checks automatically. For
more information, see Part F of this chapter, "Windows NT Monitor
Service for HP NetRAID."
•
Properties: Displays the logical drive properties of the selected logical
drive. Each logical drive can be displayed by selecting the Previous or
Next buttons.
