Known Problems and Workarounds
Symptom: OnlineDiag does not work properly when the length of the system name exceeds 8 characters.
Problem: When the length of the hostname for a system name exceeds 8 characters, OnlineDiag cannot retrieve
the hostname. So, OnlineDiag cannot function as expected.
Workaround: Change the default values of the expanded_node_host_names and uname_eoverflow kernel
parameters by completing the following steps:
1. kctune expanded_node_host_names=1
2. kctune uname_eoverflow=0
3. /sbin/init.d/diagnostic stop
4. /sbin/init.d/diagnostic start
Symptom: System port scan software can cause the diagmond process to exit.
Problem: The system port which the diagmond process uses should be explicitly used for diagmond. If other
applications try to access this port, the diagmond process exits.
Workaround:
The Diagnostic running on the system can be configured to allow only local connections. After this, an attempt
to send an IPC message to a non-local port will be rejected.
To enable this functionality (allow only local connections), follow the steps below:
1. Shutdown both STM and the EMS HW Monitors.
2. Create /var/stm/config/sys/local_only file.
3. Restart STM and the EMS HW Monitors in that order.
When enabled, the STM will no longer accept connections from remote systems.
To disable this functionality, follow the steps below:
1. Shutdown both STM and the EMS HW Monitors
2. Remove /var/stm/config/sys/local_only file.
3. Restart STM and the EMS HW Monitors in that order.
