nv action reboot system

	nv action reboot system [mode {halt \| cold \| immediate}] [force] Reboot switch system.
Syntax Description	flag	halt: Shuts down the system cold: Allow a controlled shutdown by notifying all running processes that the system is going down immediate: Reboot system immediately without notifying any running processes
	force	Force the action without asking for user confirmation.
Default	N/A
History	25.02.2002 25.02.5002 Updated reboot modes
Example	Copy Copied! `admin@nvos:~$ nv action reboot system Configuration has been modified, but not saved. Type [y] to reboot the system without saving configuration. Type [N] to abort. Do you want to continue? [Y/N] N System reboot aborted by user` Copy Copied! `admin@nvos:~$ nv action reboot system mode halt Type [y] to halt the system. Type [N] to abort. WARNING: This operation will shut down the system. You will NOT be able to turn on the system remotely. Do you want to continue? [y/N]`
REST API	POST https://<ip>/nvue_v1/system
Related commands	nv action install platform firmware files
Notes	The prompt will be displayed only if there is unsaved configuration on the switch. Otherwise, the reboot will be performed as usual. Using the halt flag will show the prompt unless force flag is passed. Using the immediate flag will not trigger the firmware upgrade flow that part of normal reboot. If the switch is in a fatal state, it will exit that state once it comes up. `nv action reboot system` will still work as usual which is equivalent to `nv action reboot system mode cold`

nv show platform ps-redundancy

	nv show platform ps-redundancy Shows power supply redundancy policy
Syntax Description	N/A
Default	N/A
History	25.02.2002
Example	Copy Copied! `admin@nvos:~$ nv show platform ps-redundancy operational applied ------- -------------- -------------- policy grid-redundant grid-redundant min-required 8`
REST API	GET https://<ip>/nvue_v1/platform/ps-redundancy
Related Commands	nv set platform ps-redundancy policy nv show system health
Notes	Supported only in systems that do not require all the power supplies to be connected.

nv set platform ps-redundancy policy

	nv set platform ps-redundancy policy {no-redundancy \| ps-redundant \| grid-redundant} Sets system power redundancy policy. When the power redundancy policy requirements are not met a health issue is raised
Syntax Description	no-redundancy	No power supply is reserved. The redundancy is not enabled.
	ps-redundant	One power supply unit is redundant to the rest. The system can work with one less power supply unit.
	grid-redundant	The power supplies are split into two logical power supply grids, each grid contains the minimum power supplies required by the system. The power supplies on the left side of the switch are one grid, and the power supplies on the right switch are the other. The system can work if all the power supplies of one grid fail.
Default	grid-redundant
History	25.02.2002
Example	nv set platform ps-redundancy policy grid-redundant
REST API	PATCH https://<ip>/nvue_v1/ platform/ps-redundancy
Related Commands	nv show system health nv show platform ps-redundancy
Notes	Supported only in systems that do not require all the power supplies to be connected.
