Description
Synchronous Transfer Rate (MB/s)
80
Sets the transfer rate for the device. The available choices are: Off, 10 MB/sec, 20
MB/sec, 40 MB/sec, or 80 MB/sec.
Data Width
16
Sets the maximum SCSI data width at which a 16-bit host adapter negotiates. The
host adapter and SCSI device must agree on a width at which they can both
operate.
For example, for a 16-bit device on a 8-bit wide cable (bus), the width at which
they can both operate is 8-bits.
Similarly, for an 8-bit device on a 16-bit wide cable (bus), the width at which they
can both operate is 8-bits.
Disconnect
On
Enables or disables disconnects for the device.
To optimize SCSI bus performance, this option should be set to On.
This should only be set to Off for troubleshooting purposes.
Read Write I/O Timeout (seconds)
10
Enters a read write time-out value in seconds for the device.
Scan for Devices at Boot Time
Yes
Specifies whether the device is scanned for at boot time.
Scan for SCSI LUNs
Yes
More advanced SCSI devices can have several logical units (LUNs). This option lets
you specify whether SCSI LUNs are scanned for at boot time.
Queue Tags
On
Specifies whether queue tags are enabled or disabled. In a multi-tasking
environment this option must be set to Yes. It should only be disabled for
troubleshooting.
Initial Boot Device
No
This setting cannot be modified.
