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 12 To replace the external paths for an external volume

1. This procedure uses the illustration above.

Disconnect external path A. See Disconnecting an external path (page 41).

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

path (page 43).

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 (page 40).

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.

Disconnecting external systems and volumes

You can disconnect a single mapped external volume, or all the mapped volumes in an external

system. You disconnect all volumes by disconnecting the system itself.
