NOTE: To enable host port failover, you must configure target ports 1 and 2 on the I/O blade as point-to-point connections (Setup > I/O Blades > Port Configuration). I/O blade target ports 1 and 2 must be attached to the same SAN fabric to provide host access. See Configuring I/O Blade Ports. |

NOTE: An error message appears if channel zoning has been configured to restrict access between target ports 1 and 2 and initiator ports 3–6 on the I/O blade. You must configure channel zoning so all target ports have access to all initiator ports. For more information, see Configuring Channel Zoning. |
The active target port becomes active by default and the other target port will go on passive standby until failover occurs.
The Progress Window appears. The Progress Window contains information on the action, elapsed time, and status of the requested operation.
