Figure 4–3 shows the components of the BOOT command. The /XMI node
number you enter corresponds to an adapter; if you have an optional VAXBI,
the /XMI node number will correspond to a DWMBB adapter and you must
then use the /BI qualifier to specify the node number of the boot device on
that VAXBI.
When using the /R5:n qualifier, see Appendix F for the values of n. The
/R3:r qualifier is used with VMS when you boot from a shadow set, where r
is two unit numbers. The first unit number is the functional unit number of
the shadow set, and the second unit number is the physical unit number of
one of the disks in the shadow set. Refer to your operating system manual
for more details.
To designate an HSC disk as the boot device, you use the /XMI and /NODE
(and /BI, if the CI adapter is a VAXBI device) qualifiers with their respective
node numbers. The /XMI node number must be an adapter, the /NODE
node number carries the CI node number of one or two HSC controllers,
and DDww, where DD specifies the device type as a disk and ww is the
hexadecimal unit of the disk boot device.
To designate a DSSI disk as the boot device, you use the /XMI and
/DSSI_NODE qualifiers with their respective node numbers. The /XMI node
number is a KFMSA adapter, the /DSSI_NODE number is the adapter that
provides access to the boot device. The /PORT qualifier specifies the DSSI
bus 1 or 2 on the KFSMA adapter and, DDww, where DD specifies the
device type and ww is the hexadecimal unit of the boot device.
To designate an Ethernet-based CD server as the boot device, use the /XMI
qualifier to specify the node number of the DEMNA or DEMFA adapter,
and, /FILENAME:x, where x specifies the 1- to 16-character file name that
the CD server loads during the boot process.
For convenience, you can store a BOOT command under a nickname, using
the SET BOOT command. Any four characters can be used for a nickname.
However, to avoid confusion, use nicknames that are different from device
specifications. Also, note that the system reserves the name DEFAULT to
specify a special saved boot specification, which is called when you enter
the BOOT command without a nickname, so DEFA should not be used as
a nickname. The default boot specification is also used when the control
panel is set to Auto Start.
You can store up to 10 saved boot specifications, in addition to the default
specification. Table 4–4 gives the specific mnemonics for each device type.
See Section 5.18.1 for details on creating nicknames for boot devices. See
Section 5.6 for more information on the BOOT command.
