Chapter 2. Maintenance Analysis Procedures (MAPs)
Entry MAP
Use the following table to determine your starting point.
Note: 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 for your use in fixing the
problem. The AIX error log and SMIT are only available when diagnostics are run
from the hard drive.
Notes:
1. 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 3-48.
2. Licensed programs frequently rely on network configuration, and system informa-
tion stored on the VPD on the operator panel control assembly (connector U2).
If the MAPs indicate that the Operator Panel Control Assembly should be
replaced, swap the VPD from the old operator panel to the new one. If the old
VPD module has to 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.
3. 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 may
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.
