SCSI device bootstrings allow you to install
the SCO OpenServer system from a device connected to the system at a
SCSI address other than the default. For example,
you should use the Stp bootstring during installation
if your tape drive is configured at a SCSI ID
that is not currently allowed as a boot device by the
installation kernel.
The syntax for SCSI bootstrings is:
periph=adapter(hanum,[bus,]id,lun)
where:
periph
is the SCSI peripheral driver name:
Sdsk
hard disk
Sflp
floptical
Srom
CD-ROM
Stp
tape
adapter
is the host adapter driver prefix
hanum
is the host adapter number: 0-7
bus
is the number of the bus on a dual or multichannel host
adapter: 0 for the primary, 1 for the secondary, and so on.
This field is optional. The default value is 0 which is
suitable for single bus adapters.
id
is the peripheral's SCSI id: 0-7 on SCSI 1
bus, 0-15 on 16-bit-wide SCSI 2 bus
lun
is the peripheral's SCSI logical unit number
(LUN): 0-7
Valid host adapter driver prefixes are defined in the file
/etc/default/scsihas.
For example, to define a SCSI tape device connected
to the first Future Domain adapter at id 4, lun 0, use the
following bootstring:
