A-4 DC8151101-00 C
NOTE: These settings apply to each SCSI ID individually.
■ Disconnects OK. When set to Yes, the device is notified that it can optionally
disconnect from the host adapter. When the drive is ready to continue
executing the command, it must re-establish the link through a reconnect
cycle. When set to No, disconnects are not allowed. The default is Yes.
If you have more than one device attached to the QLA12160 board, set
Disconnects OK to Yes for best performance.
■ Check Parity. When set to Yes, odd parity is checked and passed to the
SCSI FIFO when data is received from the SCSI bus. When set to No, the
received SCSI parity is ignored and odd parity is generated for the SCSI
FIFO. The default is Yes.
■ Enable LUNs. When set to Yes, multiple LUNs are supported. When set to
No, multiple LUNs are not supported. LUN support is typically required for
CD-ROM changers or RAID boxes that use LUNs to map drives. The default
is Yes.
■ Enable PPR. When set to Yes, the QLA12160 board attempts to negotiate
for parallel protocol request (PPR) transfers. When set to No, the QLA12160
board does not negotiate for PPR transfers. The default is Yes.
■ Enable Device. When set to Yes, the system BIOS recognizes the device
at this SCSI ID. When set to No, the system BIOS ignores the device at this
SCSI ID. The default is Yes.
■ Negotiate Wide. When set to Yes, the device supports 16-bit, wide (68-pin
cable) SCSI data transfers. When set to No, the device supports only 8-bit
(50-pin cable) SCSI data transfers. The default is Yes.
