I/O Path Failure and Failover Scenarios in Redundant Fibre Channel Fabrics for
Active/Standby Configurations With Two or More RA4000/RA4100 Arrays
continued
Description of Failure Failover Response
The Fibre Channel cable
connection between the standby
array controller in one
RA4000/RA4100 Array and its
Fibre Channel SAN Switch is
broken.
None
The Fibre Channel SAN Switch
that is connected to the active
array controller in each
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 Fibre Channel SAN Switch
that is connected to the standby
array controller in each
RA4000/RA4100 Array fails.
None
The Fibre Channel cable
connection between the Fibre
Channel SAN Switch that is
connected to the active array
controllers and a Fibre Host
Adapter 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 each RA4000/RA4100 Array, and Fibre Channel
cables.
The Fibre Channel cable
connection between the Fibre
Channel SAN Switch that is
connected to the standby array
controllers and a Fibre Host
Adapter is broken.
None
A Fibre Host Adapter connected to
the Fibre Channel SAN Switch that
is connected to the active array
controllers 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.
A Fibre Host Adapter connected to
the Fibre Channel SAN Switch that
is connected to the standby array
