Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper
task IDs.
Use the
system boot-sequence
command to define the local storage devices used to boot a router. You
can define two devices with this command:
•
The value of the
primary-device
argument defines the default device where software packages are
installed and run. This device is also the default location for router configurations.
•
The value of the
secondary-device
argument defines the device used by the
command To back up system software and configurations. This field is optional.
•
The secondary device can also be temporarily defined when the
command is
executed with the
target-device
argument. Use the
system boot-sequence
command with the
secondary-device
argument to permanently define the secondary (backup) device.
primary-device
Default device where software packages are installed and run. This device is
also the default location for router configurations. The value of the
primary-device
argument is normally
disk0:
.
secondary-device
Secondary (backup) boot device, used by the
command to
back up system software and configurations.
•
The supported storage devices are
disk0:
and
disk1:
(if installed).
Note
The value of the
secondary-device
argument must be different from
the value of the
primary-device
argument.
disable
Temporarily disables the automatic recovery mechanism.
location
node-id
Defines the boot sequence on any RP in the router. The

argument is
expressed in

/
slot
/
module
notation.
