LSI Logic SCSI Configuration Utility
LSI Logic SCSI Configuration Utility
The LSI Logic SCSI Configuration Utility lets you view and change the
default configuration for the host adapter, and all SCSI devices connected to
it, or for individual SCSI devices. If, while using this utility, you accidentally
disable all the controllers, pressing
during the POST (after the memory
test) lets you recover and configure settings.
Default Settings You Can Change
The following two tables show the configuration settings that can be
changed. The first table shows the global settings which impact the host
adapter and all SCSI devices connected to it. The second table shows the
device settings which apply to individual devices.
Settings for the Host Adapter
and All Devices
Default Settings
Description
SCAM Support
Off
LSI Logic BIOS version 4.x and above supports SCSI Plug and Play protocol called
SCAM (SCSI Configured Automatically).
Parity Checking
On
LSI Logic PCI to SCSI host adapters always generate parity, but some SCSI
devices do not. For this reason, parity checking can be disabled (Off).
1
1.
When disabling parity checking, you may have to disable disconnects for certain devices as parity checking for the re-selection phase is
not disabled. If a device does not generate parity, and it disconnects, the I/O never completes because the re-selection never completes.
Host Adapter SCSI ID
7
It is not recommended to change the host adapter ID from the default value of 7,
as this gives it the highest priority on the SCSI bus.
Scan Order
Low to High
(0-Max)
Informs the host adapter BIOS and device drivers to scan the SCSI bus from low
(0 to max) SCSI ID, or from high to low (max to 0) SCSI ID. If there is more than
one device on a SCSI bus, changing the device order changes the drive letters
which are assigned to them by the system. This will change the boot order.
Removable Media Support
None
Only used when removable disks are installed.
CHS Mapping
SCSI Plug and Play
Mapping
Defines the cyclinder head sector (CHS) values that are mapped onto an un-
partitioned disk.
