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 information 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 processor 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 Processors in Verbose Mode
 

The following example displays information about all configured 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

>0
An error occurred.
