reset. Disabled, indicates the disk array will not signal unit
attention. Enabled indicates the disk array will signal unit
attention.
when a SCSI reset (reset signal, BDR or Reset Disk array
command) is received in the first controller. When this bit
is disabled, the second controller will assert the bus reset
signal to indicate that all outstanding requests were
cleared in response to the reset. When this bit is enabled,
the second controller will not assert the SCSI reset signal
to indicate the commands were cleared. Hosts that
cannot tolerate target bus resets should enable this
setting.
respect to bus selection. When disabled, any secondary
controller present will respond to host selection. When
enabled, the secondary controller will remain off-line until
a failure of the primary controller is detected (at which
point it becomes primary). Only the primary controller will
go on-line.
SCSI bus selection during the early stages of the
initialization sequence (i.e., from about three seconds
after reset until about fifteen seconds prior to initialization
completion). When disabled, the disk array will ignore
SCSI bus selection until the late stages of initialization.
When enabled, the disk array will accept selection during
early initialization and will return BUSY status until the late
stages of initialization.
1952 Specifies the target queue depth beyond which the disk
array will return QUEUE FULL status to subsequent host
requests.
