HP HyperFabric manual

Troubleshooting HyperFabric

Running Diagnostics

Make sure 4X HyperFabric adapters are installed on the nodes. The adapter type field indicates the type of HyperFabric adapter that is installed. HMP will only run on 4X HF2 PCI (A6386A) adapters.

Check the firmware file field to make sure the firmware file name for each HyperFabric adapter ends in 32c. All of the HyperFabric adapters in the fabric must have firmware files that end in 32c for HMP to run. If this is not the case, run the following commands in the order listed below:

$ clic_shutdown

$ clic_init

(The answer to the interoperability question must be consistent on all nodes in the fabric.)

$ clic_start

All of the IP addresses in the fabric must be in the same subnet. The lower 10 digits of all of the IP addresses in the fabric must be unique. Every HyperFabric adapter in the fabric must be able to communicate with every other HyperFabric adapter in the fabric.

Every HyperFabric adapter in the fabric must be connected, point-to-point or via a switch. If one of the adapters in the fabric is not connected, HMP will not be able to run.

Run diagnostics to make sure data can be transferred on the HyperFabric adapters. Use the following command (which is detailed in the next section of this chapter):

$ clic_diag

If you are running an Oracle application using HMP and traffic does not appear to be flowing after completing all of the steps listed above, check the ORAHOME/rdbms/log/alert*log files. The display should show Cluster Interconnect IPC version:Oracle using HP-HMPlogged in the alert log files. If not, recompile the Oracle application to run using HMP according to the instructions provided in the Oracle Installation and Administration Guide.
