Chapter 5 Configuring Your Library

Working With FC I/O Blades

Dell PowerVault ML6000 User’s Guide 120

To enable host port failover, you must configure target ports 1 and 2 on

the FC I/O blade as point-to-point connections (Setup > FC I/O Blades >

Port Configuration

). FC I/O blade target ports 1 and 2 must be attached to

the same SAN fabric to provide host access. The primary active port is

used for host communications, while the passive standby port is kept

idle. In addition, channel zoning must be configured so that target ports 1

and 2 have access to all initiator ports (ports 3–6) (Setup > FC I/O Blades >

Channel Zoning

). If these conditions are not met, an error message will

display when you attempt to enable host port failover.

For information on configuring FC I/O blade ports and channel zoning,

see Configuring FC I/O Blade Ports on page 110 and Configuring FC I/O

Blade Channel Zoning on page 111.

The library generates a Reliability, Availability, and Serviceability (RAS)

ticket when port failover occurs. Examine the ticket to determine the

reason for the failover. When the failed port is repaired, the port must be

re-enabled to make it available for host port failover as the standby or

active port. For more information, see Repairing and Enabling a Failed

Target Port on page 121.

Note: The current feature implementation does not support

arbitrated loop or target/initiator mode.

Note: Ports on the 4 Gb FC I/O blade used for failover must connect

to the same SAN fabric.

Note: When both target ports on the FC I/O blade are attached to the

same SAN fabric, you may see duplicate media changer

devices (partitions) being reported. To stop this from

happening, you need to enable host port mapping and

configure host mapping. For more information, see

Configuring Host Mapping on page 118.

Note: When Fibre Channel port 2 is selected to be the active port in a

host port failover configuration, the active port can switch to

the default setting, port 1, following a reboot. Reconfigure the

host port failover settings so that the intended port is the

active port.
