Logical Drive
Choose this option to perform the listed actions. You must first select the logical drive on which you
want to perform these options.
•
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, 5, 10, 30, or 50 is used.
Check consistency should be run if the system shuts down irregularly, e.g., if the system
hangs or suffers a power failure. Check consistency will always remedy inconsistencies. 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 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.
•
View Performance: Displays the selected adapter read/write performance.
•
Properties: Displays the selected logical drive properties: Raid level, size (MB) Stripe Size,
Write Policy, Ready Policy, Cache Policy, Virtual Sizing, Number of Stripes, and State.

Choose this option to select a physical device and to perform the operations listed below. When you

SCSI Channel
Choose this option to select a SCSI channel on the currently selected adapter. You can perform the
following operations on the selected channel.
•
Deactivate Channel: Deactivates the selected channel.
•
Activate Channel: Activates the selected channel. Be sure that TermPWR is provided for all
active channels.
•
Terminate High 8 Bits: Enables termination on the selected channel for the upper eight bits
and disable termination on the adapter for the lower eight bits. This setting is required if the
selected SCSI channel is terminated with 8-bit devices at both ends.
