Chapter 3. Maintenance Analysis Procedures (MAPs)
This chapter contains maintenance analysis procedures (MAPs).
Notes:
1. When possible, run online diagnostics in service mode. Online diagnostics perform
additional functions, compared to standalone diagnostics. This ensures that the
error state of the system is captured in NVRAM (non-volatile random access
memory) for your use in fixing the problem. The AIX error log and SMIT are only
available when diagnostics are run from the hard drive.
2. If more than eight digits are displayed in the operator panel, use only the first eight
digits to find the error in the tables. The digits that display beyond the first eight
digits are location codes that can assist you in diagnosing the problem. See
“Location Codes” on page 9.
3. Licensed programs frequently rely on network configuration and system information
stored on the VPD (vital product data) module on the operator panel control
assembly. If the MAPs indicate that the operator panel control assembly should be
replaced, swap the VPD module from the old operator panel to the new one. If the
existing VPD module must be replaced, call technical support for recovery
instructions. If recovery is not possible, notify the system owner that new keys for
licensed programs may be required.
4. If a network adapter or the I/O board is replaced, the network administrator must be
notified so that the client IP addresses used by the server can be changed. In
addition, the operating system configuration of the network controller might need to
be changed in order to enable system startup. Also check to ensure that any client
or server that addresses this system is updated.
Quick Entry MAP
Use the following table to determine your starting point.
If you replace FRUs or perform an action and the problem is still not corrected, go to
“MAP 1540: Minimum Configuration” on page 50 unless otherwise indicated in the
tables.
If you replace FRUs or perform an action and the problem is corrected, go to "MAP
410: Repair Checkout" in the
RS/6000 and
