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.

If a port is shut down, unblocking that port does not initialize the port.

To block or unblock port addresses in a VSAN using Device Manager, follow these steps:

  1. Choose FICON > VSANs.
  2. Select a VSAN ID and click Port Configuration.
  3. Click in the Blocked column for the port that you want to block.
  4. Click Apply to save the changes.
