(Command Lines)

Using the Base Time-Out Option
Command line option: timeout=

30

Valid options:

Any integer value 30 to 999999999

Function:

Specify the minimum value (in seconds) for command
time-out.

Possible Impact:

Insure system integrity when using a slow device.

If a device is slow, you should increase this value to insure the device has adequate
time to respond to a command issued to it before the command times out.

Using the Sorting of Read Requests Option
Command line option: sort=

enable

Valid options:

enable, disable

Function:

Enable/disable sorting of read commands to be issued to
devices.

Possible Impact:

Enabling normally yields increased performance based on
the target device controller.

If the devices connected to a host adapter are of a non-buffered architecture, such as
the Symbios Logic 6298 disk array, then sorting of reads may result in a perfor-
mance degradation, since the absence of cache provides no benefit for sorted re-
quests. In this instance you should disable the sort option. On most disk drives, an
on-board cache allows for reading ahead of data, and by sorting read requests, the
probabilities of achieving a cache hit are greatly increased, thus increasing the over-
all performance of the driver.

Using the Shared Interrupts Option
Command line option: shared_int=

disable

Valid options:

enable, disable

Function:

Support shared interrupts.

Possible Impact:

Enabling may cause a performance degradation.

You should enable the shared interrupt option any time a PCI card other than a
Symbios Logic controller is added to a system which assigns all PCI cards the same
interrupt value. The added card must support shared interrupts. The driver automati-
cally handles the case of more than one Symbios Logic host adapter sharing an
interrupt.

Using the Wide SCSI Option
Command line option: wide=

enable

Valid options:

enable, disable

Function:

Enable/Disable support of wide SCSI.

Possible Impact:

No wide SCSI support available.
