VirtualDriveResponse | ATTO Technology 2500C specification

SpeedWrite

When enabled, improves the performance of WRITE commands to SCSI devices attached to the iPBridge. Specify SCSI bus (sb), target (st), LUN (sl) of a mapped SCSI device or (all) for each currently mapped device

Set syntax: set SpeedWrite scsi [sb st sl all] [enabled disabled]

Get syntax: get SpeedWrite scsi [sb st sl all]

SpeedWriteDefault

When enabled, SpeedWrite performance enhancement is set as the default for any subsequent SCSI devices mapped manually or via an AutoMap operation. If disabled, the iPBridge does not attempt SpeedWrite

performance enhancement to newly-mapped SCSI devices.

Default: disabled

Set syntax: set SpeedWriteDefault [enabled disabled]

Get syntax: get SpeedWriteDefault

VirtualDriveResponse

Allows the iPBridge to provide proxy responses to SCSI INQUIRY and TEST UNIT READY commands if a SCSI device selection times out or is busy. Host systems can then assign devices consistently regardless of the device’s state during the execution of the commands.

Default: disabled

Set syntax: set VirtualDriveResponse [enabled disabled]

Get syntax: get VirtualDriveResponse
