Changing SCSI Settings

The SCSI settings control the transfer of information over the SCSI channel connecting the host and the
disk array. The default SCSI settings listed in
adapters, and in most cases should not be changed.
NOTE! Before changing any SCSI setting, you should understand what the SCSI setting does,
and what effect changing it will have on disk array operation. Be aware that using an incorrect
SCSI setting may make it impossible for the host and disk array to communicate properly. In this
case, it will be necessary to use the disk array control panel to return the SCSI setting to its
original value to reestablish communication.
To change SCSI settings, type:
arraymgr { -W | -T | -P | -m | -r } {on|off} <array-id>

Changing the Controller SCSI ID

Changing the SCSI ID directly impacts the operating system's ability to access the disk array. Before
performing this task, check your operating system documentation for information on how to change the
SCSI ID of a disk subsystem.
To change the controller SCSI ID, type:
arraymgr -C {X|Y} addr <array-id>
addr is the new address (0 – 15) for the indicated controller

Switching Primary Controllers

In dual-controller disk array configurations, the array automatically switches to the secondary controller if
the primary controller fails. However, you can switch controllers manually if necessary. This will cause the
secondary controller to assume the role of primary controller.
To switch primary controllers, type:
arraymgr -c { X | Y } <array-id>
