Moving ports

When selecting Move Ports, HCD offers the possibility of moving control unit, channel path or switch port connections on the same switch or from other switches to the selected target switch.

To perform this action, select the target switch for a port move action on the Switch List (see Figure 73). The panel Actions on selected switches appears and the action Move Ports can be selected. You can also reach this panel directly by typing in the action code  x  next to the appropriate switch in the Switch List menu. This brings up the following panel Move Ports to a Target Switch.

This panel contains data entry fields for the ports to be moved. It is also possible to move a range of ports from a switch to the target switch occupying subsequent port addresses starting with the target port address specified. The target switch field in this panel has been preset and cannot be changed.

Depending on the context, HCD performs the following as part of the Move Ports action:

  • Copies the attributes of the source port to the target port (and set the target port to installed, if necessary).
  • Disconnects all source ports from the connected units.
  • Connects all target ports to the units previously connected to the source ports.
  • Copies existing port configurations of the source port if the move is on the same switch and port configurations exist. The source port configurations will be set to default, i.e., all dynamic and dedicated connections are reset.
  • Changes the dynamic switch of the connected channel path to the target switch if the source switch serves as a dynamic switch and the target switch is different from the source switch.
  • Changes the link address to the target port if the source port serves as a link address to a channel path connection for a control unit and is connected to a control unit or another switch.
Note:
HCD does not perform any checks on whether the user also moves implied ports as well. For example, if a channel path is moved to another switch, the control units that are connected to the channel path must also be moved. Moving a control unit may imply that connected channel paths must be moved as well. If not all implied ports are moved, the configuration may become invalid and a validation error will be shown either during the Move Ports action or later during the Build Production IODF action.
Note:
If the target switch has switch configurations defined and the port move occurs between different switches, then the switch configurations must be adapted after the port move action.

The Move Ports action is especially of value when consolidating switches or installing new switches.
