The lgrpinfo tool prints information about the lgroup hierarchy, contents, and characteristics. The lgrpinfo tool is a Perl script that requires the Solaris::Lgrp module. This tool uses the liblgrp(3LIB) API to get the information from the system and displays it in the human-readable form.
The lgrpinfo tool prints general information about all of the lgroups in the system when you call it without any arguments. When you pass lgroup IDs to the lgrpinfo tool at the command line, the tool returns information about the lgroups that you specify. You can specify lgroups with their lgroup IDs or with one of the following keywords:
This keyword specifies all lgroups and is the default behavior.
This keyword specifies the root lgroup.
This keyword specifies all of the leaf lgroups. A leaf lgroup is an lgroup that has no children in the lgroup hierarchy.
This keyword specifies all of the intermediate lgroups. An intermediate lgroup is an lgroup that has a parent and children.
When the lgrpinfo tool receives an invalid lgroup ID, the tool prints a message with the invalid ID and continues processing any other lgroups that are passed in the command line. When the lgrpinfo tool finds no valid lgroups in the arguments, it exits with a status of 2.
