nodeboot(8) -- Reboot a confluent node to a specific device

SYNOPSIS

nodeboot [options] <var>noderange</var> [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

EXAMPLES

  • Booting n3 and n4 to the default boot behavior: # nodeboot n3-n4
    n3: default
    n4: default
    n3: on->reset
    n4: on->reset

  • Booting n1 and n2 to setup menu: # nodeboot n1-n2 setup n2: setup
    n1: setup
    n2: on->reset
    n1: on->reset

  • Booting n3 and n4 to network: # nodeboot n3-n4 net
    n3: network
    n4: network
    n4: on->reset
    n3: off->on
