System Console Commands, Continued
Boot
The boot command starts the bootloader, which loads the
operating system and starts it. The boot command causes the
system to exit console mode and enter program mode. Table 4–7
lists boot commands and their meanings.
Syntax:
>>> boot/qualifier device, second_device
Table 4–7 BOOT Command Syntax
Term Meaning
/qualifier This optional qualifier sets the value for R5 for
the bootloader. It is used to select a boot on the
disk, or a conversational boot.
The qualifier can be specified in either of the
following formats:
/R5:XXXXXXXX
/XXXXXXXX
device, This optional term is the primary boot device.
If no device is specified, the system attempts to
boot the default device. You can set the default
boot device with the SET BOOT command.
second_device This optional term is the device the bootloader
tries to boot if the primary boot device fails.
Example:
This example shows the system performing a conversational boot
from DKA200. If the system cannot boot from DKA200, it tries a
conversational boot from DKA400.
>>> BOOT/R5:00000001 DKA200, DKA400
