6.3 AIX troubleshooting
An extensive guide to AIX troubleshooting can be found at:
Some of the common problems we have observed are shown in the following
Log in to the Flexible Service Processor’s (FSP) Advanced System Management
Interface (ASMI) from the HMC. In the GUI, select Service Applications →
Service Focal Point → Service Utilities, select CEC, and select Selected →
Launch ASM Menu.
From the ASMI, you can look into the Error/Event log and search for a B70069Ex
entry. These entries are “Informational” but will point to a possible InfiniBand
problem. When an InfiniBand cable is disconnected, a B70069E6 entry will
appear. When the cable has been reconnected, a B70069E9 code will appear in
the FSP error/event log. The meaning of these entries is shown in Table 6-1.
Table 6-1 B70069Ex codes
Reference code Description
B700 69E6 The cable connection to the InfiniBand
switch is broken. Verify that the cable is
connected and the switch is powered on.
After repairing the problem, verify that the
connection has been restored by using the
InfiniBand Network Manager.
B700 69E9 Initial communication has occurred with
the Subnet Manager. No service action
required. The CEC and switch firmware
are now communicating.
