Summary of I/O Path Failure and Failover
Scenarios for Redundant Fibre Channel Fabrics
Table 2-3 identifies possible I/O path failure events in redundant Fibre
Channel Fabrics for active/standby configurations with one RA4000/RA4100
Array and the failover response, if any, implemented by Secure Path for each
failure.
Table 2-3
I/O Path Failure and Failover Scenarios in Redundant Fibre Channel Fabrics for
Active/Standby Configurations With One RA4000/RA4100 Array
Description of Failure Failover Response
The active array controller in the
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 the RA4000/RA4100 Array, and Fibre Channel cables.
The standby array controller in the
RA4000/RA4100 Array fails.
None
The Fibre Channel cable
connection between the active
array controller 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 the RA4000/RA4100 Array, and Fibre Channel cables.
The Fibre Channel cable
connection between the standby
array controller and its Fibre
Channel SAN Switch is broken.
None
The Fibre Channel SAN Switch
connected to the active array
controller 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 the RA4000/RA4100 Array, and Fibre Channel cables.
