nodepower(8) -- Check or change power state of confluent nodes
|
||
|
|
=========================================================
|
||
|
|
|
||
|
|
## SYNOPSIS
|
||
|
|
|
||
|
|
`nodepower <noderange>`
|
||
|
|
`nodepower <noderange> [on|off|boot|shutdown|reset|status]`
|
||
|
|
|
||
|
|
## DESCRIPTION
|
||
|
|
|
||
|
|
**nodepower** with only a noderange will retrieve current power state of nodes
|
||
|
|
through confluent. When given an additional argument, it will request a change
|
||
|
|
to the power state of the nodes. The following arguments are recognized:
|
||
|
|
|
||
|
|
* `on`: Turn on the specified noderange. Nothing will happen to nodes of
|
||
|
|
the noderange that are already on.
|
||
|
|
* `off`: Immediately turn off the specified noderange, without waiting for OS
|
||
|
|
to shutdown. Nothing will happen to nodes of the noderange that are already on.
|
||
|
|
* `boot`: Immediately boot a system. This will power on nodes of the noderange
|
||
|
|
that are off, and reset nodes of the noderange that are on. The previous state
|
||
|
|
will be reflected in the output.
|
||
|
|
* `shutdown`: Request the OS gracefully shut down. Nothing will happen for
|
||
|
|
nodes that are off, and nodes will not shutdown if the OS fails to gracefully
|
||
|
|
respond.
|
||
|
|
* `reset`: Request immediate reset of nodes of the noderange. Nodes that are
|
||
|
|
off will not react to this request.
|
||
|
|
* `status`: Behave identically to having no argument passed at all.
|
||
|
|
|
||
|
|
## EXAMPLES
|
||
|
|
* Get power state of nodes n1 through n4:
|
||
|
|
`# nodepower n1-n4`
|
||
|
|
`n1: on`
|
||
|
|
`n2: on`
|
||
|
|
`n3: on`
|
||
|
|
`n4: off`
|
||
|
|
|
||
|
|
|
||
|
|
* Forcing a reboot of nodes n1-n4:
|
||
|
|
`# nodepower n1-n4 boot`
|
||
|
|
`n3: on->reset`
|
||
|
|
`n1: on->reset`
|
||
|
|
`n2: on->reset`
|
||
|
|
`n4: off->on`
