A Appendix Diagnosing and Resolving Shared Disk Problems Introduction When one or more nodes in a Compaq Parallel Database Cluster Model PDC/O5000 (referred to here as the PDC/O5000) cannot properly join the cluster, you need to consider two possible causes: I A problem related to the shared disk storage in the cluster's MA8000/EMA12000 Storage Subsystems is preventing one or more nodes from accurately viewing or successfully accessing the available shared storage resources. I A connectivity problem exists either within the cluster interconnect or the client LAN, preventing one or more nodes from communicating with the other nodes or preventing a client from communicating with the cluster. This appendix describes the procedures you should follow to diagnose and resolve suspected shared disk problems in a PDC/O5000 cluster. Figure A-1 identifies, in a flowchart format, the sequence of tasks you should perform to diagnose, isolate, and resolve shared disk problems in the PDC/O5000. A detailed description of each task is provided in the following sections of this appendix.
