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. SunOS 5.8 Last change: 19 Feb 1999 1 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
