4.2.5 SCSI Device Configuration
Press <Enter> to bring up SCSI Device Configuration menu.
4.2.5.1 Initiate Sync Negotiation
Synchronous negotiation is a SCSI feature that allows the SCSI channel and its attached
SCSI devices to transfer data in synchronous mode. Synchronous data transfer is faster
than asynchronous data transfer. The Initiate Sync Negotiation field determines whether
the channel initiates synchronous negotiation with the SCSI device.
Options
yes (*)
no
4.2.5.2 Maximum Sync Transfer Rate
This field specifies the maximum synchronous data transfer rate that the channel supports.
Options
40.0 (*) / 32.0 / 26.8 / 20.0 / 16.0 / 13.4 / 10.0
4.2.5.3 Enable Disconnection
This field specifies whether the channel allows a SCSI device to disconnect from the SCSI
bus. Enabling disconnection allows the channel to perform other operations on the SCSI
bus while the SCSI device is temporarily disconnected.
Options
yes (*)
no
4.2.5.4 Initiate Wide Negotiation
This field specifies whether the channel attempts 16-bit instead of 8-bit data transfer.
Options
yes (*)
no
4.2.5.5 Send Start Unit Command
This field specifies whether the channel sends the Start Unit command to the SCSI device.
Enabling this option reduces the load on the computer’s power supply by allowing the
channel to turn on SCSI devices one-at-a-time when the computer boots. Otherwise, all
SCSI devices turn on at the same time.
Options
yes
no (*)
