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.

Maintenance Commands                                  psrinfo(1M)

     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.
