NAME

nodeboot - Reboot a confluent node to a specific device

SYNOPSIS

nodeboot [options] <noderange> [default|cd|network|setup|hd]

DESCRIPTION

nodeboot reboots nodes in a noderange. If an additional argument is given, it sets the node to specifically boot to that as the next boot. This performs an immediate reboot without waiting for the OS. To set the boot device without inducing a reboot, see the nodesetboot command.

OPTIONS

-b, --bios

For a system that supports both BIOS and UEFI style boot, request BIOS style boot if supported (some platforms will UEFI boot with this flag anyway).

-u, --uefi

This flag does nothing, it is for command compatibility with xCAT's rsetboot

-p, --persist

For a system that supports it, mark the boot override to persist rather than be a one time change. Many systems do not support this functionality.

-m MAXNODES, --maxnodes=MAXNODES

Specify a maximum number of nodes to boot, prompting if over the threshold

-h, --help

Show help message and exit

default

Request a normal default boot with no particular device override

cd

Request boot from media. Note that this can include physical CD, remote media mounted as CD/DVD, and detachable hard disks drives such as usb key devices.

network

Request boot to network

setup

Request to enter the firmware configuration menu (e.g. F1 setup) on next boot.

hd

Boot straight to hard disk drive
