I understand that it is recommended to reboot sequentially after OS upload.

The following information is recommended for OS release notes.

Thank you.

 

Upgrading in a Multicontroller Network
In a multicontroller network (a network with two or more Aruba controllers), special care must be taken to upgrade all controllers based on the controller type (master or local).

Be sure to back up all controllers being upgraded, as described in Backing up Critical Data on page 17.

For proper operation, all controllers in the network must be upgraded with the same version of ArubaOS software.

For redundant (VRRP) environments, the controllers should be of the same model.

To upgrade an existing multicontroller system to this version of ArubaOS:
1. Load the software image onto all controllers (including redundant master controllers).

2. If all the controllers cannot be upgraded with the same software image and rebooted simultaneously, use the following guidelines:

a. Upgrade the software image on all the controllers. Reboot the master controller.
After the master controller completes rebooting, you can reboot the local controllers simultaneously.

b. Verify that the master and all local controllers are upgraded properly.
