•
Cache Flush Timings: Sets the cache flush interval to once every 2, 4, 6, 8, or 10 seconds.
The default setting is four seconds.
•
View/Update Rebuild Rate: View or change the rebuild rate for the adapter.
•
Alarm Control: Enables, Disables, or Silences the onboard alarm tone generator. The default
setting is Enabled.
•
Diagnostics: The hardware diagnostic tool performs the following hardware tests:
◊ On-board memory test
◊ NVRAM test
◊ Parity check
◊ DMA test
◊ Timer test
◊ Interrupt test
◊ Hardware register test
•
Auto Rebuild: Enables/Disables Auto Rebuild of the physical drives
•
Initiator ID: Changes the Initiator ID Assumed by the SCSI Chips at System Bootup
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; this should be done for every logical drive you
configure.
•
Check Consistency: Verifies the correctness of the redundancy data in the selected logical
drive; this option is only available if RAID level 1, 3, or 5 is used. Check consistency should
be run if the system shuts down irregularly, e.g., if the system hangs or suffers a power
failure. It is also recommended to run consistency checks every 2-4 weeks to ensure that bad
blocks on the disk drive are mapped out. (See the “Check Consistency Feature.”) Check
consistency will always remedy inconsistencies. Check consistency will only fail because
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 due to the physical drives going offline.
•
Properties: Displays the selected logical drive properties of RAID level, size (MB) 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
NetServer are listed. Hot key functions are displayed at the bottom of the screen. To access drive
information, press F2, and view logical drives by pressing F3. 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
NOTE You do not need to use the Format option if you simply want to erase existing
information on your hard drives, such as a DOS partition. Initializing the logical
drive(s) erases that information.
