Chapter 16. Using the SSA Command Line Utilities
The commands that are described here allow you to get access from the command line
to some of the functions that are available in the SSA service aids. The commands are
very simple and are intended for use mainly from within shell scripts. They do not
provide many error checking routines or error messages. If you need such facilities, use
the SSA service aids (see Chapter 17, "SSA Service Aids" on page 373).
Under most conditions, a command prints a usage string if the syntax is incorrect. No
message is printed, however, if the command fails. If the command runs without error,
the return code is 0. If an error occurs, the return code is a value other than 0.

|
microcode file must be located in the /etc/microcode directory, or the microcode

Specifies the name of the microcode file to be downloaded. This flag can be
used with the -d flag or the -u flag.
When this flag is used with no other flags, the latest level of enclosure
microcode that is available in the /etc/microcode directory is downloaded to all
available SES enclosures if that latest level is higher than the version that
exists in the enclosure. If this flag is used with the -f flag, the file that is
specified by the -f flag is downloaded to all available SES enclosures if the
level of that file is higher than the level that exists in the enclosure.
