Troubleshooting the Compaq ProLiant Clusters HA/F100 and HA/F200 6-9 Table 6-3 Solving Shared Storage Problems continued Problem Possible Cause Data on shared storage appears to be overwritten. MSCS may not be loaded and therefore cannot manage access to drive volumes in the shared storage. The second node cannot connect to the shared drives. Physical connection from the second node to the Compaq StorageWorks Fibre Channel Storage Hub does not exist. Shared RA4000 drives are not assigned the same drive letters on both nodes. The second node was powered on before the storage hub or the RA4000. Action 1. Ensure MSCS is loaded on both cluster nodes. 2. Using the Control Panel Service applet on each node, verify the cluster service is running. 1. Verify all Fibre Channel cables are properly connected to the GBIC-SW modules. For details on how to connect the GBIC-SW modules and the Fibre cables, see the Compaq RA4000 Storage System User Guide. 2. Verify that all Fibre Channel cables are properly connected to their GBIC-SW modules. Run Windows NT Disk Administrator on each node to verify all shared drives are assigned identical, permanent drive letters. Shut down the second node, turn it off, then turn it on. continued
