Dell Chassis Management Controller Version 3.10 for Dell EMC PowerEdge VRTX User's Guide

The CMC configuration file, <filename>.cfg, is used with the racadm config -f <filename>.cfg command to create a simple text file. The command allows you to build a configuration file (similar to a .ini file) and configure the CMC from this file.

You may use any file name, and the file does not require a .cfg extension (although it is referred to by that designation in this subsection).

RACADM parses the .cfg file when it is first loaded on to the CMC to verify that a valid group and object names are present, and that simple syntax rules are being followed. Errors are flagged with the line number that detected the error, and a message explains the problem. The entire file is parsed for correctness, and all errors display. If an error is found in the .cfg file, write commands are not transmitted to the CMC. You must correct all errors before any configuration can take place.

To check for errors before you create the configuration file, use the -c option with the config subcommand. With the -c option, config only verifies syntax and does not write to the CMC.

Follow these guidelines when you create a .cfg file:

• If the parser encounters an indexed group, it is the value of the anchored object that differentiates the various indexes.

  The parser reads in all of the indexes from the CMC for that group. Any objects within that group are modifications when the CMC is configured. If a modified object represents a new index, the index is created on the CMC during configuration.

• You cannot specify a desired index in a .cfg file.

  Indexes may be created and deleted. Over time, the group may become fragmented with used and unused indexes. If an index is present, it is modified. If an index is not present, the first available index is used.

  This method allows flexibility when adding indexed entries where you do not need to make exact index matches between all the CMCs being managed. New users are added to the first available index. A .cfg file that parses and runs correctly on one CMC may not run correctly on another, if all indexes are full and you must add a new user.

• Use the racresetcfg subcommand to configure both the CMCs with identical properties.

  Use the racresetcfg subcommand to reset the CMC to original defaults, and then run the racadm config -f <filename>.cfg command. Make sure that the .cfg file includes all desired objects, users, indexes, and other parameters. For a complete list of objects and groups, see the Chassis Management Controller for PowerEdge VRTX RACADM Command Line Reference Guide .

  • CAUTION: Use the racresetcfg subcommand to reset the database and the CMC Network Interface settings to the original default settings and remove all users and user configurations. While the root user is available, other users’ settings are also reset to the default settings.
• If you type racadm getconfig -f <filename> .cfg , the command builds a .cfg file for the current CMC configuration. This configuration file can be used as an example and as a starting point for your unique .cfg file.
