MCCS CLI is the function to send a command to the MCCS service in the system's command window mode.
MCCS provides the following types of CLI: mclog to add arbitrary log, mcgroup to command a group, and mcres to command the resource group.
In general, CLI prepares scripts (*.sh and etc) to send various commands to the MCCS service.
CLI is located in $MCCS_HOME\bin.

After registering script file in PowerLinux MCCS and use CLI command, FullPath($MCCS_HOME/bin/mclog) must be used.

Table of Contents

When you install MCCS, the initial user account ID is set to 'admin' and the password is set to 'password'.
When you run the CLI command, you need to enter the ID and the password. Otherwise, the above initial ID and password will be used.
Thus, when you change the initial user password, you must enter the ID/password in the CLI command as options.
