Operating the Control Panel
Using Control Panel Menus
Term Power
NOTE! This command requires a SCSI Reset or power cycle to take effect.
Termination Power. Enables (default) or disables SCSI Term Power (SCSI Terminator Power). If Term
Power is enabled, the disk array will supply power to the SCSI terminator connected to the array and to the
SCSI termination on the HBA.
Unit Attn
NOTE! This command requires a SCSI Reset or power cycle to take effect.
Unit Attention. Enables (default) or disables SCSI Unit Attn (Unit Attention) for the primary array
controller. If Unit Attn is enabled and a command failed with Unit Attention status, the controller reports to
the host that a Reset has occurred since the last command was executed.
DRR
NOTE! This command requires a SCSI Reset or power cycle to take effect.
Disable Remote Reset. When DRR is ON or enabled (default), it prevents a host SCSI reset from resetting
both disk array SCSI buses. With DRR set to ON, disk array controllers are not allowed to reset their own
SCSI bus, even if the host resets that controller. If DRR is set to OFF, a host SCSI reset will also allow that
controller to reset both disk array SCSI buses.
This parameter controls the SCSI bus reset behavior or the remote (other) disk array controller when a
SCSI reset results in both disk array controllers processing a reset request. These include an ordinary reset
signal, a bus device reset, or a reset subsystem command. When DRR is set to ON, the remote controller
will not assert the SCSI reset signal to indicate that the commands were cleared. Hosts that cannot tolerate
target bus resets should have DRR set to ON. When DRR is OFF, the remote controller will assert the bus
reset signal to indicate that all outstanding requests were cleared in response to the reset.
VEB
NOTE! This command requires a SCSI Reset or power cycle to take effect.
Very Early Busy. VEB instructs the disk array to return a BUSY response during its power-on sequence. If
VEB is enabled, the disk array will return a BUSY status to the host rather than simply ignore any
commands during the power-on sequence. This will alert the host system to the presence of the disk array
and thus avoid the possibility of the host system "timing out" before the disk array is ready.
