4.3.2.4 Using the Tagged Queuing Option
•
Syntax: qtags=[targetIDlist] or
qtag=[targetIDlist] or
tag=[targetIDlist]
•
Default value: on
•
Valid entries: on, off
•
Function: Enables/disables use of simple/ordered tagged command
queueing.
Enabling the qtags option causes the driver to issue tagged I/O requests
to the devices that support tagged queuing. Tagged I/O requests are not
issued to devices that do not support tagged queuing. Depending on the
drive controller, use of queue tags increases throughput of the device.
However, the optimal number of queue tags is based on the specific
device type. Tagged queuing may result in improved I/O throughput in
devices that support it.
4.3.2.5 Using the Scan Option
•
Syntax: scan=[targetIDlist][lunIDlist]
•
Default value: list
•
Valid entries: on, off, list, or order
•
Function: Specifies the Logical Unit Numbers (LUNs) to scan.
This option allows you to change the default for scanning LUNs per
target ID on the SCSI bus.
4.3.2.6 Using the Slot Option
•
Syntax: slot=[targetIDlist]
•
Default value: None
•
Valid entries: 0–10099
•
Function: Specifies the slot instance number of the LSI controller to
which the load instance applies.
The slot option specifies the LSI controller SCSI channel (embedded
chip or host adapter) that pertains to the current load. This information
is required to load the driver. If this information is not specified on the
load line, the driver will prompt for the slot number.
