Collecting service data
The first-failure data capture (FFDA) tool monitors, tracks, and captures system hardware errors and
hardware and software inventory information, and reports serviceable problems directly to Support. You can
also choose to collect data manually. This tool is integrated into the IMM2. All information that is sent to is
encrypted and stored in a secure database and used for improved problem determination.
For more information about accessing the IMM2, see Chapter 4 “Accessing the IMM2” on page 47.
