Note 1 = This ID is assigned to the HBA and should not be selected for the drive ID
Note: You can also change SCSI IDs by connecting a SCSI address-
selection switch to pins 1 through 8.
If you change the drive’s default SCSI ID, avoid using SCSI
IDs 0 and 1 (which typically are assigned to a boot drive) and
SCSI ID 7 (which typically is assigned to SCSI controllers or
host bus adapters).
Note: If you disable parity checking, the drive still generates a parity
bit.
