=head1 DESCRIPTION
|
|
|
|
B<rpower> controls the power for a single or range of nodes, via the out-of-band path.
|
|
|
|
=head1 OPTIONS
|
|
|
|
=over 4
|
|
|
|
=item B<on>
|
|
|
|
Turn power on.
|
|
|
|
=item B<onstandby>
|
|
|
|
Turn power on to standby state
|
|
|
|
=item B<-T>
|
|
|
|
The value could be B<lpar> or B<fnm>. The tooltype value B<lpar> is for xCAT and B<fnm> is for CNM. The default value is "B<lpar>". For cold start in the large cluster, it will save a lot of time if the admins use "B<rpower> I<noderange> B<onstandby> B<-T> B<fnm>" to power on all the CECs from the management node through the B<fnm> connections.
|
|
|
|
=item B<lowpower>
|
|
|
|
Turn CEC to low power state (state EOCT). This is a disruptive operation which requires the CEC to be powered off prior to entering low power mode. And we can use power off command to get out of lowepower state.
|
|
|
|
=item B<rackstandby>
|
|
|
|
Places the rack in the rack standby state. It requires that all CECs and DE be powered off before it will run.
|
|
|
|
=item B<exit_rackstandby>
|
|
|
|
Exit Rack standby will be the default state that a rack goes into when power is initially applied to the rack. It simply moves the BPA from Rack standby to both bpa's in standby state.
|
|
|
|
=item B<resetsp>
|
|
|
|
Reboot the service processor. If there are primary and secondary FSPs/BPAs of one cec/frame, it will reboot them almost at the sametime.
|
|
|
|
=item B<softoff>
|
|
|
|
Attempt to request clean shutdown of OS (may not detect failures in completing command)
|
|
|
|
=item B<off>
|
|
|
|
Turn power off.
|
|
|
|
=item B<suspend>
|
|
|
|
Suspend the target nodes execution
|
|
|
|
=item B<stat>|B<state>
|
|
|
|
Print the current power state/status.
|
|
|
|
=item B<reset>
|
|
|
|
Send a hard reset.
|
|
|
|
=item B<boot>
|
|
|
|
If off, then power on.
|
|
If on, then hard reset.
|
|
This option is recommended over B<cycle>.
|
|
|
|
=item B<cycle>
|
|
|
|
Power off, then on. For IBM Flex Compute Node, just reset the node.
|
|
|
|
=item B<of>
|
|
|
|
Boot the node to open firmware console mode.
|
|
|
|
=item B<sms>
|
|
|
|
Boot the node to open firmware SMS menu mode.
|
|
|
|
=item B<-m> I<table.column>==I<expectedstatus> B<-m> I<table.column>=~I<expectedstatus>
|
|
|
|
Use one or multiple B<-m> flags to specify the node attributes and the expected status for the node installation monitoring and automatic retry mechanism. The operators ==, !=, =~ and !~ are valid. This flag must be used with -t flag.
|
|
|
|
Note: if the "val" fields includes spaces or any other characters that will be parsed by shell, the "attr<oper-ator>val" needs to be quoted. If the operator is "!~", the "attr<operator>val" needs to be quoted using single quote.
|
|
|
|
=item B<--nodeps>
|
|
|
|
Do not use dependency table (default is to use dependency table). Valid only with B<on|off|boot|reset|cycle> for blade power method and B<on|off|reset|softoff> for hmc/fsp power method.
|
|
|
|
=item B<-r> I<retrycount>
|
|
|
|
specify the number of retries that the monitoring process will perform before declare the failure. The default value is 3. Setting the retrycount to 0 means only monitoring the os installation progress and will not re-initiate the installation if the node status has not been changed to the expected value after timeout. This flag must be used with -m flag.
|
|
|
|
=item B<-t> I<timeout>
|
|
|
|
Specify the the timeout, in minutes, to wait for the expectedstatus specified by -m flag. This is a required flag if the -m flag is specified.
|
|
|
|
Power off, then on.
|
|
|
|
=item B<-h>|B<--help>
|
|
|
|
Prints out a brief usage message.
|
|
|
|
=item B<-v>|B<--version>
|
|
|
|
Display the version number.
