Compaq Parallel Database Cluster Model PDC/O2000 for Oracle8i and Windows 2000 Administrator Guide

Cluster Architecture 2-35
Table 2-4 identifies possible I/O path failure events for active/standby
configurations in redundant Fibre Channel Fabrics with two or more
RA4000/RA4100 Arrays and the failover response, if any, implemented by
Secure Path for each failure.
Table 2-4
I/O Path Failure and Failover Scenarios in Redundant Fibre Channel Fabrics for
Active/Standby Configurations With Two or More RA4000/RA4100 Arrays
Description of Failure Failover Response
The active array controller in one
RA4000/RA4100 Array fails.
Secure Path forces a complete failover to the standby I/O path
components, including the standby Fibre Host Adapter in each
node, the other Fibre Channel SAN Switch, the standby array
controller in each RA4000/RA4100 Array, and Fibre Channel cables.
The standby array controller in one
RA4000/RA4100 Array fails.
None
The Fibre Channel cable
connection between the active
array controller in one
RA4000/RA4100 Array and its
Fibre Channel SAN Switch is
broken.
Secure Path forces a complete failover to the standby I/O path
components, including the standby Fibre Host Adapter in each
node, the other Fibre Channel SAN Switch, the standby array
controller in each RA4000/RA4100 Array, and Fibre Channel cables.
