The basic host adapter settings are the SCSI
Select
settings most likely to require
modification:
Host Adapter SCSI ID This option sets the host adapters SCSI ID. The default
setting is 7, which allows the host adapter to support narrow SCSI devices in addi-
tion to wide SCSI devices. Dell recommends that you leave the host adapter set
to SCSI ID 7.
SCSI Parity Checking This option determines whether the host adapter veri-
fies the accuracy of data transfer on the SCSI bus. Most SCSI devices support
SCSI parity, so the default is Enabled. You should disable SCSI Parity Checking
if any SCSI device connected to the host adapter does not support SCSI parity. If
you are unsure if a device supports SCSI parity, consult the documentation for
the device.
Host Adapter SCSI Termination This option sets termination on the host
adapter. The default for the Adaptec AIC-7860 host adapter is Enabled; the
default for the AIC-7890 and 2940U2W host adapters is Enabled. Dell recom-
mends that you leave this option set to the default.
