nodesetboot(8) -- Check or set next boot device for noderange
====================================================
## SYNOPSIS
`nodesetboot <noderange>`
`nodesetboot [options] <noderange> [default|cd|network|setup|hd|floppy]`
## DESCRIPTION
Requests that the next boot occur from the specified device. Unless otherwise
specified, this is a one time boot option, and does not change the normal boot
behavior of the system. This is useful for taking a system that normally boots
to the hard drive and startking a network install, or to go into the firmware
setup menu without having to hit a keystroke at the correct time on the console.
Generally, it's a bit more convenient and direct to use the nodeboot(8) command,
which will follow up the boot device with an immediate power directive to take
effect. The `nodesetboot` command is still useful, particularly if you want
to use `nodesetboot <noderange> setup` and then initiate a reboot from within
the operating system with ssh or similar rather than using the remote hardware
control.
## 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).
* `-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.
* `-u`, `--uefi`:
This flag does nothing, it is for command compatibility with xCAT's rsetboot
* `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.
* `floppy`:
Request boot from floppy. Generally speaking firmware uses this to mean a USB
flash drive or similar (whether virtual or physical).
* `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
* Set next boot to setup for four nodes:
`# nodesetboot n1-n4 setup`
`n1: setup`
`n3: setup`
`n2: setup`
`n4: setup`
* Check boot override settings on four nodes:
`# nodesetboot n1-n4`
`n1: setup`
`n2: setup`
`n3: setup`
`n4: setup`
