NAME

psradm − Stops and starts a processor

SYNOPSIS

/usr/sbin/psradm -f [-v] [[-a] [processor_id ...]]

/usr/sbin/psradm -n [-v] [[-a] [processor_id ...]]

DESCRIPTION

On a multi-processor system, the psradm command puts one or more processors off line (stops a processor) or on line (starts a processor).  The processor_id variable specifies an integer that uniquely identifies a processor.  Use the psrinfo command to display processor identification numbers. 

Note that you cannot stop the master processor in a multi-processor system. 

You must be root to use this command. 

The /var/adm/wtmp file contains information about successful processor state transitions. 

FLAGS

-fPuts the specified processor off line. 

-nPuts the specified processor on line. 

-aSpecifies that all the processors except the master processor be put off line or on line. 

-vDisplays a message about the status of the operation performed on each processor. 

EXAMPLES

The following example puts processors 2 and 3 off line:

# psradm -f 2 3

The following example puts all the processors except the master processor on line:

# psradm -n -a
