lmutil application

In addition to lmgrd, you can use the lmutil application to manage some aspects of the License Server. This application is available on all platforms.

lmutil application arguments

The following table provides a list of the valid arguments for most lmutil utilities.

Table 1. lmutil argumentsThis table describes lmutil arguments.
Argument	Description
-c <license_file_path>	Most lmutil utilities need the path to the license file. This is specified with the -c `license_file_path` argument.
-help	Displays usage information and exits.
-v	Displays the version of the utility and exits.
-verbose	Displays a longer description for errors that are found.

For the first argument of a lmutil command, you can specify one of the following utilities:

lmdown—gracefully stops a license server system (manager and vendor daemon)
lmhostid—calculates a hostid to identify a system or user
lmreread—instructs the license server system to reread license and option files, and start new vendor daemons
lmstat—displays the status of a license server system
lmswitch—controls license server log location and size
lmver—displays the version of a FLEXnet executable

The following table provides more information about the most common or useful commands that are helpful for troubleshooting License Server issues.

Table 2. Useful lmutil commandsThis table describes Imutil commands.
Command	Purpose
lmutil lmhostid	Obtains the MAC address system information from the current system. A MAC address is a valid node-locking choice (HOSTID=) and can also be used in the SERVER line of a license file to identify the License Server. If multiple MAC addresses are listed by the command, use the first one. For example: lmutil lmhostid Verify the MAC address with its use in any license files. If the MAC address does not match any of the relevant uses, a mistake might have been made when the system information was entered for license activation.
lmutil lmreread	Forces the License Server to instruct the Dell vendor daemon to reread the license file for changes. Use this command if new or changed license files are made available. This command allows the License Server and the Dell vendor daemon to continue to run and to update the internal cache of the license features from newly updated license files. For example: lmutil lmreread -vendor EMCLM
lmutil lmstat	Use this command to determine the running status of the License Server lmgrd. For example: lmutil lmstat -a
lmutil lmdown	When you provide the name of the license file that you used to start the License Server, this command gracefully shuts down the License Server and Dell vendor daemon. To ensure that the proper processes are terminated, specify the license file name. You might be asked to confirm the shutdown before proceeding. For example: lmlmutil lmdown -c `<license_file_list>`
