Block And Unblock Ports; Block A Port - HP 316095-B21 - StorageWorks Edge Switch 2/24 Service Manual

Block and Unblock Ports

This section describes procedures to block or unblock the switch Fibre Channel ports.
Blocking a port prevents the attached device or fabric switch from communicating. A
blocked port continuously transmits the offline sequence (OLS).
NOTE: When a port is blocked, the operation of an attached Fibre Channel device is disrupted.
Do not block a port unless directed to do so by a procedural step or the next level of support.

Block a Port

To block a port:
1. Notify the customer the port is to be blocked. Ensure the customer's system
administrator quiesces Fibre Channel frame traffic through the port.
2. At the HAFM server, open the HAFM application. The Product View displays.
3. Select the icon representing the switch with the port to be blocked. The Hardware
View for the selected switch displays.
4. Move the pointer over the port and right-click the mouse to open a list of menus.
5. Select Block Port. The Block Port n dialog box displays (n is the port number).

Hardware View.
— The green LED associated with the port extinguishes at the switch.
