2-64 Compaq Parallel Database Cluster Model PDC/O2000 for Oracle8i and Windows 2000 Administrator Guide Summary of I/O Path Failure and Failover Scenarios for Redundant FC-ALs Table 2-7 identifies possible I/O path failure events in redundant FC-ALs for active/standby configurations with one RA4000/RA4100 Array and the failover response, if any, implemented by Secure Path for each failure. Table 2-7 I/O Path Failure and Failover Scenarios in Redundant FC-ALs for Active/Standby Configurations With One RA4000/RA4100 Array Description of Failure The active array controller in the RA4000/RA4100 Array fails. The standby array controller in the RA4000/RA4100 Array fails. The Fibre Channel cable connection between the active array controller and its Storage Hub or FC-AL Switch is broken. The Fibre Channel cable connection between the standby array controller and its Storage Hub or FC-AL Switch is broken. The Storage Hub or FC-AL Switch connected to the active array controller fails. The Storage Hub or FC-AL Switch connected to the standby array controller fails. The Fibre Channel cable connection between a Fibre Host Adapter and the Storage Hub or FC-AL Switch connected to the active array controller is broken. Failover Response Secure Path forces a complete failover to the standby I/O path components, including the standby Fibre Host Adapter in each node, the other Storage Hub or FC-AL Switch, the standby array controller in the RA4000/RA4100 Array, and Fibre Channel cables. None Secure Path forces a complete failover to the standby I/O path components, including the standby Fibre Host Adapter in each node, the other Storage Hub or FC-AL Switch, the standby array controller in the RA4000/RA4100 Array, and Fibre Channel cables. None Secure Path forces a complete failover to the standby I/O path components, including the standby Fibre Host Adapter in each node, the other Storage Hub or FC-AL Switch, the standby array controller in the RA4000/RA4100 Array, and Fibre Channel cables. None Secure Path forces a complete failover to the standby I/O path components, including the standby Fibre Host Adapter in each node, the other Storage Hub or FC-AL Switch, the standby array controller in the RA4000/RA4100 Array, and Fibre Channel cables. continued
