Chapter 3. Maintenance Analysis Procedures (MAPs)
This chapter contains maintenance analysis procedures (MAPs) for the system.
Entry MAP
Use the following table to determine your starting point. 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. Licensed programs frequently rely on system information stored on the VPD module
on the operator panel assembly. If the MAPs indicate that the operator panel
assembly should be replaced, swap the VPD module from the old operator panel to
the new one. If recovery is not possible, notify the system owner that new keys for
licensed programs may be required.
2. If a network adapter 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.
3. If you are servicing an SP system, go to the Start-of-Call MAP 100 in the SP
Systems Service Guide .
4. If you are servicing a clustered Eserver system, go to the start of call MAP 100 in
the Clustered Eserver Installation and Service Guide.
Symptom
You have a problem that does not prevent the
system from booting and all the I/O drawer
operator panels are functional.
You have a problem that does not prevent the
system from booting and the secondary I/O
drawer operator panel is not functioning.
You do not have a symptom.
You have an SRN.
The system stops and a 3-digit number is
displayed in the operator panel display.
Starting Point
Go to the Fast Path MAP in the Diagnostics
Information for Multiple Bus Systems .
Replace the following parts one at a time in the
secondary I/O drawer with the non-functioning
operator panel.
1. Secondary I/O drawer operator panel.
2. Secondary I/O drawer operator panel cable.
Go to MAP 0020 in the Diagnostics Information
for Multiple Bus Systems .
Go to the Fast Path MAP in the Diagnostics
Information for Multiple Bus Systems .
Record SRN 101-xxx, where xxx is the 3-digit
number displayed in the operator panel display,
then go to the Fast Path MAP in the
Diagnostics Information for Multiple Bus
