Procedure 4 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 51) .
2. Disconnect the cable for external path A, then remove it. See “Removing, replacing an external
path ” (page 53) .
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 50) .
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.
You disconnect a volume or system in order to perform the following operations:
•
Turn off the power supply of the local or external storage system
•
Delete an external volume’s mapping
•
Access a mapped external volume or volumes from the external storage system
