About this task
• Recabling port connections is a nondisruptive procedure when your shelf has multipath-HA
connectivity.
You recable the first shelf across both sets of ports on each controller so that when you hot-
add the second shelf, both shelves have more resilient connectivity.
• You move one cable at a time to maintain connectivity to the shelf at all times during this
procedure.
Steps
1. Recable the existing shelf's connections across both sets of ports on each controller, as
applicable to your system.
Moving a cable does not require any wait time between unplugging the cable
from one port and plugging it into another port.
If you have an...
DM7100F HA pair
DG7000 HA pair
2. Verify that the recabled shelf is cabled correctly.
1.3.3. Prepare to manually assign drive ownership for a hot-add
If you are manually assigning drive ownership for the DM240N drive shelf you are hot-adding, then
you need to disable automatic drive assignment if it is enabled.
Then...
If needed, you can reference cabling illustrations
showing an existing single shelf and the recabled
shelf, in a two shelf configuration.

a. On controller A, move the cable from port e0d to slot 5 Port b
(e5b).
b. Repeat the same cable move on controller B.
