Chapter 7. Reference
This section provides reference information for OFM, including accessibility, the
CLI command and events.
BladeCenter Open Fabric Manager components
The OFM configuration file and AMM Web interface are essential for OFM
functionality.
Configuration file
The OFM configuration file is the central tool for managing the OFM domain and
contains the definitions that you need for a domain of up to 100 BladeCenters. You
can generate it automatically, save it and edit it to conform to the needs of a
specific domain and then apply it to the domain. You also have the option of
creating your own configuration file.
The configuration file is a Comma Separated Value (CSV) file. Each non-blank and
non-comment line defines a single entity within a domain of BladeCenters. The
entities currently defined are BladeCenters, Slots and Port Entries, where a port is
a single network device within a slot, which can have multiple definitions – one
for each interface type.
The file is organized hierarchically by BladeCenters, Slots and Ports, with ample
comment lines included to act as a guide to editing the file if needed. IBM
recommends that you maintain the original structure as much as possible in order
to retain the readability of the file. For certain purposes it might be appropriate to
extract a smaller section of the domain into a new file so that you can update a
particular BladeCenter or a particular blade individually.
To view an example of a configuration file, see "Example: Configuration file" on
page 48.
Comments section
There are two types of comments: line comments and field comments.
// this is a line comment
localhost/# this is a field comment
Line comments start with two slashes (//). The system ignores anything between
this symbol and the end of the line. You can insert line comments anywhere in the
file. However, inserting a comment inside a pair of quote marks results in a No
closing quote error.
You can insert field comments in any field. Field comments start with a slash-hash
(/#). The system ignores anything between this symbol and the end of the field.
Inserting a field comment inside a pair of quotes does not cause an error.
Comments are included in the maximum line-length (currently 512 bytes including
newlines). Very long comments should be broken over several lines to improve
readability and to prevent exceeding the line-length limit. If you exceed the
line-length limit, the system issues the following error: Input line is too long.
