Netapp ACP Inactive No In-Band Connectivity
If you plug in a new shelf to an existing Netapp system you would be firstly setting the shelf ID, connecting the SAS cables and ensuring the system can see the disks, that the connectivity status is Multi-Path HA and then you would begin to connect the ACP cables.
Once you cable the ACP connectivity and type the following command:
::> node run NODE1 storage show acp
You may see that the ACP Connectivity Status is Partial Connectivity and that under the column Shelf Module, NA. Looking further to the right under the Status column you will notice it may say inactive (no in-band connectivity)
To fix this you must have a look at the Shelf Module column and determine which shelf and module is missing, in the example above it is shelf 23 module A.
As long as your system is cabled correctly and it displays Multi-Path HA in the sysconfig output, you would locate shelf 23 and remove module A for about 2 mins. After 2 mins has passed you can re-plug the module back into the shelf.
If you then re-type the command:
::> node run NODE1 storage show acp
You should see that shelf 23 module A is now online and that the ACP Connectivity Status is Full Connectivity.
