2. You may choose between two different kinds of switch activation:

Single switch activation

For single switch activation, use the Activate Switch Configuration panel to:

• Specify the switch ID and the switch configuration ID that is to be written to the switch.
• Select how to handle an existing ESCON Manager lock if it is in use by another user.

  I/O Operations uses a locking mechanism to serialize connectivity changes across multiple users and systems. This lock allows only one user (or program) to control I/O Operations command processing at a time. If more than one user at your installation is given the ability to enter I/O Operations commands, they must synchronize their usage of I/O Operations to avoid delays or contention for I/O Operations resources.

Multiple switch activation

For multiple switch activation, use the Activate Switch Configuration panel to:

• Specify only the switch configuration ID and no Switch ID. A panel is displayed showing all switches that have a configuration under the specified name.

  Switches that are not connected to any switch device are marked with a disabled marker # in the action column, and cannot be selected for activation. The panel shows 'YES' in the 'More?' column if there are more than one control unit and one device. If there is only one control unit and one device, the 'More?' column is left blank. HCD uses the switch devices that are connected to the active system.
• Select the switches that will be activated simultaneously.

  When you have finished your selection, press the Enter key. A confirm panel is displayed. On this panel you have to confirm if you want the active switch configuration of all switches shown in the list to be updated.

  Note:

  In case a switch activation fails, no switch will be activated, the rule is "none or all".
