NAME
      psrinfo - displays information about processors
 


SYNOPSIS
      psrinfo [ -v ]  [ processor_id ... ]
 
      psrinfo -s processor_id
 


DESCRIPTION
      psrinfo displays information about processors.
 
      Without the  processor_id operand, psrinfo displays one line
      for  each configured processor, displaying whether it is on-
      line, non-interruptible (designated by  no-intr),  off-line,
      or  powered  off, and when that status last changed. Use the
      processor_id  operand  to  display  information   about    a
      specific processor.
       See OPERANDS.
 


OPTIONS
      The following options are supported:
 
      -s processor_id
            Silent mode. Displays 1 if  the specified processor is
            fully  on-line,  and  0 if  the specified processor is
            non-interruptible, off-line, or powered off.
 
            Use silent mode when using  psrinfo in shell scripts.
 
      -v    Verbose mode.  Displays additional  information  about
            the  specified processors,  including: processor type,
            floating point unit type and clock speed.  If  any  of
            this   information   cannot  be  determined,   psrinfo
            displays unknown.
 


OPERANDS
      The following operands are supported:
 
      processor_id
            The processor ID of the processor about which informa-
            tion is to be displayed.
 
            Specify processor_id as an individual processor number
            (for example, 3), multiple processor numbers separated
            by spaces (for example, 1 2 3), or a range of  proces-
            sor numbers (for example, 1-4). It is also possible to
            combine   ranges   and   (individual   or    multiple)
            processor_ids (for example, 1-3 5 7-8 9).
 
 EXAMPLES
      Example 1: Displaying information about all configured  pro-
      cessors in verbose mode.

      The following example displays information about all config-
      ured processors in verbose mode.
 
      psrinfo -v
 
      Example 2: Determining if a processor is on-line.
 
      The following example uses  psrinfo in  a  shell  script  to
      determine if a processor is on-line.
 
      if [ "`psrinfo -s 3 2> /dev/null`" -eq 1 ]
      then
           echo "processor 3 is up"
      fi
 
 EXIT STATUS
      The following exit values are returned:
 
      0     Successful completion.
 
      >0    An error occurred.
