4.6 Clearing the Enclosure Zoning Password

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.

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.

To Clear the Enclosure Zoning Password

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.

1. At the back of the J4500 array, locate the Enclosure Zoning Password Clear button (see Enclosure Zoning Password Clear Button ).
2. Using a paper clip, press and hold the recessed button on the back panel for five seconds and then release.

   The enclosure zoning password for both SAS fabrics (A and B) is cleared.

3. From the CAM management host, select Clear password from the Administration page and saving the setting for both of the array's SAS domains.

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