Use the Select Channel Zoning screen to configure channel zoning for the selected I/O blade.

Channel zoning, also called port zoning, configures access to an entire Fibre Channel and all the LUNs on that channel for the exclusive use of a host or group of hosts on a single port. Channel zoning enables you to control access between target ports 1 and 2 and initiator ports 3 through 6 on an I/O blade. By default, all target ports have access to all initiator ports.

Channel zoning applies to attached FC tape drive LUNs seen through the initiator ports on the I/O blade. Channel zoning does not affect media changer LUNs (partitions). If you want to map hosts to media changer LUNs through an I/O blade, you must use the I/O blade's FC host mapping feature.

If host port failover is enabled on the I/O blade, channel zoning must be configured so that all target ports have access to all initiator ports.

To configure channel zoning:

    1. Do any of the following:
      • To permit access, select a check box where the target port and initiator port meet.
      • To restrict access, clear the check box where the target port and initiator port meet.
    2. Select Apply.

Note: At any time, select Cancel to exit the Select Channel Zoning screen.
