SCSI Drive IDs
SCSI bus device addresses are automatically assigned in the hot-swap drive bay depending on the slot number
in which they are installed. The address jumper on the storage backplane is used to override the default
addresses. The default settings are listed in the following table and can be set manually to different addresses at
the option. The storage backplane can be configured as two separate SCSI buses or as a single SCSI bus using
a jumper cable. Note that:
♦
The SCSI ID addressing is independent of the single or dual SCSI bus arrangement. Make sure to select
unique SCSI IDs for all SCSI devices on the SCSI bus.
♦
You must use a wide SCSI host adapter to set SCSI IDs greater than seven.
♦
The CD-ROM drive and tape IDs must be set manually. Refer to the manufacturer's documentation for
information on setting drive IDs.
