NAME    [Toc]    [Back]

       psrinfo,  pinfo - Displays processor administration information

SYNOPSIS    [Toc]    [Back]

       /usr/sbin/psrinfo -n

       /usr/sbin/psrinfo [-v] [processor...]

       /usr/sbin/psrinfo -s  processor

       /usr/sbin/pinfo [-v] [processor...]

OPTIONS    [Toc]    [Back]

       Displays the number of processors in the system.   Enables
       verbose  mode  which provides more information on the processor,
 such as its type and speed.  Writes only a boolean
       value to standard output.  The -s option requires a single
       processor  identification  number  (processor).   The   -s
       option is intended to be used in scripts.  A value of 1 is
       output if the specified processor is on line.  A value  of
       0 is output if the specified processor is off line.

DESCRIPTION    [Toc]    [Back]

       The  psrinfo  and pinfo commands display information about
       processors.  The processor variable specifies the  processor
  identification number, which is a unique integer that
       identifies the processor.   If  you  do  not  specify  any
       options or a processor identification number, the commands
       display information about all processors.

RESTRICTIONS    [Toc]    [Back]

       The -v correctly reports processor speeds on  system  that
       contains  mixed-speed  CPUs,  but the processor type might
       not be reported correctly.

EXAMPLES    [Toc]    [Back]

       The following is an example of the default prsinfo command
       output (no options or processor identification numbers):


              greene:> psrinfo 0       on-line   since 11/03/1999
              09:41:34   1         on-line     since   11/03/1999
              09:41:34   2         off-line    since   11/03/1999
              08:41:34


              The following example shows how to use the  psrinfo
              command  with  the  -s  option in a shell script to
              determine the state of the processor with an  identification
 number of 1:

              if  [  "`psrinfo  -s  1 2> /dev/null`" -eq 1 ] then
                   echo "processor 1 is up" else      echo  "processor
  1  is  down" fi The following example shows
              how to use the psrinfo command with the -v option:

              % psrinfo -v Status of processor 0 as of:  05/23/00

              processor.  Status of processor 1 as  of:  05/23/00
