Step 3. Disable Ultra SCSI support using the procedure described
Section 3.5.1, “Enabling/Disabling Ultra SCSI Support,” once
the system is booted.
If the system operates properly without Ultra SCSI enabled, it
is highly likely that the SCSI bus cable and terminators are not
configured correctly for Ultra SCSI. Refer to the LSI Logic host
adapter user’s guide for information on Ultra SCSI cabling
requirements.
Step 4. Verify that the devices appear with the proper value for speed
in the SDMS SCSI BIOS banner at boot time. Refer to
Chapter 2, “SCSI BIOS and Configuration Utility,” for additional
details.
Problems with scanners.
If a scanner is not operating properly (either the scanner is not found or
a SCSI interface error occurs during scanning), it is possible that the third
party scanner drivers do not support the auto request sense feature of
LSI Logic host adapters. Disable the auto request sense feature as
described in
Section 3.5.2, “Disabling Auto Request Sense Support,” and
try the scanner operation again.
The system hangs at boot, has a long boot time, or SCSI device not
available.
Some older SCSI devices do not tolerate Domain Validation operations.
At system boot time, Domain Validation is performed to test the data
integrity of the SCSI bus between the host adapter and each target
device. With some older SCSI devices, these operations can cause the
device to stop responding to SCSI commands.
Refer to the Command Line Options Section 3.5.4, “Disabling Domain
Validation Support,” page 3-17 . Disable this support as described either
for a specific problem SCSI target or all adapters controlled by the
SYMC8XX.MPD , SYM_HI.MPD , or SYM_U3.MPD driver.
3.5 Using the Command Line Options
This section describes various command line options that allow changes
to the host adapter.
