Replacing all external paths

You can replace the primary and alternate paths used by an external volume. Doing this requires one path to remain in Normal status at all times, which is shown in the following figure.

Procedure

1. This procedure uses the illustration above.

Disconnect external path A. See Disconnecting an external path .

2. Disconnect the cable for external path A, then remove it. See Removing and replacing an external path .

3. Make sure the cable for external path C is connected, and then add this path to an existing path group. See Adding an external path to an existing path group .

When external path C status is Normal, then both external path B and external path C are set, and you can replace the next path.

4. Disconnect external path B.

5. Disconnect the cable for external path B, then remove it.

6. Make sure the cable for external path D is connected, and then add this path to an existing path group.

When external path D status is Normal, then both external path C and external path D are set. The paths have all been replaced.
