The Ethernet is used to boot in two ways. Figure 4–6 and Figure 4–7
illustrate these methods.
A trigger boot initiates a BOOT command from a command system, which
sends the command over the Ethernet to the executor system, which causes
a boot in the target system (the VAX 6000 series system). The target system
loads its boot program from the boot device that is designated as the default.
(The default can be a local disk or the Ethernet.) The target system must
have its control panel key switches at Auto Start and Enable. Commands
are issued only from the command node, not from the target machine.
Target-initiated booting (Figure 4–7) is initiated by a console BOOT
command from the target system. This BOOT command specifies an
Ethernet controller as the boot device:
BOOT /XMI:m /R5:v EX0
(See Section 4.3 and Section 5.6 for more information on the BOOT
command.)
Information must be entered in the executor system for the boot to succeed.
Although the BOOT command is initiated at the VAX 6000 target node, the
executor node Network Control Program’s (NCP) volatile database requires
an entry for the target node.
Section 4.9 shows an example of a target-initiated Ethernet boot.
