OptiConnect cluster diagnostics
These informational system reference codes (SRCs) are the most common OptiConnect network-related messages that are posted in the Product Activity Logs of systems in a cluster.
B600 69A8 Link Operational
This informational SRC indicates that a fiber-optic link has become operational again. The satellite system posts the message. The message is normally seen after the redundant link cable is reconnected.
B600 69C1 Loss of Contact With the Remote System
This informational SRC indicates that a remote system in an OptiConnect network has been brought down or has crashed. To prevent this SRC during the normal shutdown of a system in the cluster, run ENDSBS QSOC *IMMED before bringing the system down.
B600 69D8 Link Non-operational
This informational SRC indicates that the fiber-optic link between two systems has become nonoperational. Pulling a fiber-optic cable can cause this SRC. Because the OptiConnect hardware provides redundant links, the hardware can switch over to the other fiber-optic link and continue to operate both buses on the one remaining cable.
When you turn on a hub system, this SRC can occur during the initial program load (IPL) and can be ignored.
