nodesetboot(8) -- Check or set next boot device for noderange
|
|
====================================================
|
|
|
|
## SYNOPSIS
|
|
|
|
`nodesetboot <noderange>`
|
|
`nodesetboot [options] <noderange> [default|cd|network|setup|hd|usb|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
|
|
|
|
* `-m`, `--maxnodes`:
|
|
Specify a maximum number of nodes to modify next boot device, prompting if
|
|
over the threshold
|
|
|
|
* `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).
|
|
|
|
* `usb`:
|
|
Request boot from usb. 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`
|
