7-14 Compaq Parallel Database Cluster Model PDC/O1000 for Oracle8i and Windows 2000 Administrator Guide A Cluster Node Cannot Connect to the Shared Drives I Verify that a physical connection exists between each Fibre Host Adapter and its Fibre Channel SAN Switch, FC-AL Switch, or Storage Hub. G Verify that a GBIC-SW module is properly installed in each Fibre Host Adapter, all active ports on each Fibre Channel SAN Switch, FC-AL Switch, or Storage Hub, and each 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."

Compaq Parallel Database Cluster Model PDC/O1000 for Oracle8i and Windows 2000 Administrator Guide
A Cluster Node Cannot Connect to the Shared
Drives
■
Verify that a physical connection exists between each Fibre Host
Adapter and its Fibre Channel SAN Switch, FC-AL Switch, or
Storage Hub.
G
Verify that a GBIC-SW module is properly installed in each Fibre
Host Adapter, all active ports on each Fibre Channel SAN Switch,
FC-AL Switch, or Storage Hub, and each RA4000 Array Controller.
G
Verify that all Fibre Channel cables are properly connected to their
GBIC-SW modules.
■
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.
■
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.
■
If the node is still unable to connect to the RA4000/RA4100 Arrays,
refer to Appendix A, “Diagnosing and Resolving Shared Disk
Problems.”
