7-14 Compaq Parallel Database Cluster Model PDC/02000 for Oracle8i and Windows 2000 Administrator Guide A Cluster Node Cannot Connect to the Shared Drives I Verify that a physical connection exists from each node to each Fibre Channel SAN Switch, FC-AL Switch, or Storage Hub. G Verify the shortwave Gigabit Interface Converter (GBIC) modules are properly seated in the affected Fibre Channel SAN Switch, FC-AL Switch, or Storage Hub, and RA4000 Array Controller. G Verify that all Fibre Channel cables are properly connected to their GBIC-SW modules. I Verify all nodes can access the shared storage in the RA4000/RA4100 Arrays. On each node, start Disk Management to verify that the same shared disk resources are seen from every node in the cluster. I The shared storage components must be powered on before the servers. If any cluster node was powered on before the Fibre Channel SAN Switches, FC-AL Switches, Storage Hubs, or the RA4000/RA4100 Arrays, shut down the node and restart. I If the node is still unable to connect to the RA4000/RA4100 Arrays, refer to Appendix A, "Diagnosing and Resolving Shared Disk Problems." Troubleshooting Secure Path For detailed information about troubleshooting Secure Path software, refer to the troubleshooting documentation provided with Secure Path. Secure Path Guidelines for Windows 2000 Advanced Server The following rules and guidelines apply to the operation of Secure Path software in a PDC/O2000 cluster running Windows 2000 Advanced Server: I Due to restrictions imposed by Secure Path, no more than eight logical drives (LUNs) can be assigned to each pair of RA4000 Array Controllers in an RA4000/RA4100 Array. I There is no support for Windows 2000 dynamic disks. I Windows NT fault-tolerant driver (for the host-based RAIDsets) cannot not be used in conjunction with Secure Path.
