The file module initialization may have failed because of a duplicate IP
address:
The control enclosure may have been set up with an IP address which is already in
use by another machine on your network but the initial setup of the file modules
has failed. Refer to Checking that IP addresses are not already in use from the
Information Center, under the Installing topic.
Installation error codes
The system generates an error code that provides a recommended action if the
installation fails.
Guide to using the error code table
1. Always check the entire system for any illuminated error lights first and refer
to the problem systems appropriate maintenance manual. If no lights are
illuminated, continue to step 2.
2. Match the error code noted in the results.txt file to the installation error codes
list in Table 34 on page 52. If there are multiple errors, the first error listed is
the most critical and should be addressed first.
3. Refer to Table 33 to match the code (A-I) to the recommended action. Follow
the suggested action, in order, completing one before trying the next.
4. If the recommended action or actions fail, call the IBM Support Center.
