When creating storage zones on your J4500 array, use the Common Array Manager (CAM). CAM allows you to set a zoning password for each of the array's SAS domains (each domain equates to one of the array's SAS fabrics: A or B). The zoning passwords are stored in the array expanders and in CAM, and are used to prevent unauthorized changes to storage zones. If the array's zoning password is ever forgotten, or becomes corrupt, it can be cleared using the enclosure zoning password clear button on the back of the J4500 array.
Note - Using the enclosure zoning password clear button clears the zoning password for both of the J4500 array's SAS domains. It does not clear zoning configurations.
After clearing the zoning password on the array enclosure, you will also need to clear the zoning password for each of the array's SAS domains stored in CAM. This can be done from the CAM management host. Once the password is cleared in both places, you can use CAM to assign a new password to each of the array's SAS domains.
Note - Clearing the password in both places is important to ensure the passwords stored in the array and in CAM match. Some CAM array maintenance operations use the enclosure zone password during execution to ensure the action is authorized.
Clearing the enclosure zoning password is done by pressing a recessed button at the rear of the array. This operation may be performed with the enclosure running.
The enclosure zoning password for both SAS fabrics (A and B) is cleared.

Once that is done, you can assign new zoning passwords using CAM.
