Description
You should not disable the host channel
when in single-port mode.
In dual-port mode, you can disable a
channel when you plan to shut down the
host on that channel.
You may need to change the host
channel's SCSI target ID when you have
existing devices at ID 1 (the default), or
when you are adding more than one
controller to a system.You can set the
target ID to any number between 0 and
15.
The controller has just one LUN that you
can change when you configure the host
channels. You only need to assign a
controller LUN if you are using the
Configuration Application Program
Interface (CAPI) to configure the
controller over a host channel via SCSI
protocol extensions.
You have two options for setting the
LUN:
None—Use this setting if you are not
I
using CAPI to configure the controller
(This change takes effect immediately
unless the controller LUN is currently
in use.)
Any number between 0 and 63—Select
I
a specific number if you want the
controller's LUN to stay the same when
you reboot.

Information on page 5-5
Turn this option on (select Yes) if you find
that failover takes a long time. This option
tells the controller to reset the SCSI bus
after a failover and speeds failover in
some situations.
