SCSI Select Settings
SCSI Bus Interface Definitions
The following settings are the SCSISelect settings most likely to
require any modification:
Host Adapter SCSI ID— Sets the SCSI ID for the
AAA-131U2/133U2. The AAA-131U2/133U2 is set to SCSI ID
7, which gives it the highest priority on the SCSI bus. We
recommend you do not change this setting.
SCSI Parity Checking—When set to Enabled, verifies the
accuracy of data transfer on the SCSI bus. Leave this setting
Enabled unless any SCSI device connected to the AAA-131U2/
133U2 does not support SCSI parity.
Host Adapter SCSI Termination—Sets the termination setting
for each SCSI channel. We recommend that you leave the
ULTRA2-LVD/SE connector setting for Channel A at Auto. For
the remaining termination settings, leave them set to Enable
unless the AAA-131U2/133U2 does not form one of the physi-
cal endpoints of the channel (the AAA-131U2/133U2 is not
connected at the end of the internal cable).
SCSI Device Configuration
To configure settings for a specific SCSI device, you must know the
SCSI ID assigned to that device (see Using the SCSI Disk Utilities on
page A-4.)
Initiate Sync Negotiation—When set to Yes, synchronous data
transfer negotiation (Sync Negotiation) between the device
and SCSI channel is initiated by the SCSI channel. Leave this
setting set to Yes unless any SCSI device connected to the chan-
nel does not support Sync Negotiation.
Maximum Sync Transfer Rate—Determines the maximum
synchronous data transfer rate that the SCSI channel supports.
For most SCSI devices, use the maximum rate supported.
