Configuring Port Blocking

If you block a port, the port is retained in the operationally down state. If you unblock a port, a port
initialization is attempted. When a port is blocked, data and control traffic are not allowed on that port.
Physical Fibre Channel port blocks will continue to transmit an Off-line state (OLS) primitive sequence
on a blocked port.
Caution You cannot block or prohibit the CUP port (0XFE).
If a port is shut down, unblocking that port does not initialize the port.
The shutdown/no shutdown port state is independent of the block/no block port state.
Note
To block or unblock port addresses in a VSAN using Device Manager, follow these steps:
Choose FICON > VSANs.
Step 1
Step 2 Select a VSAN ID and click Port Configuration.
You see the FICON Port Configuration dialog box for the selected VSAN (see
Figure 36-14
Step 3 Check the Blocked check box for the port that you want to block.
Step 4 Click Apply to save the changes.
