(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.
