Upgrading ESXi hosts running Avaya Oceana or Avaya Analytics virtual machines

Last Updated : Sep 25, 2023 |

Hosts running virtual machines that are part of Avaya Oceana®, Avaya Analytics™ and/or Avaya Breeze® platform, must be kept up-to-date, including VMware ESXi.

Host software maintenance and updates must be planned into a maintenance windows where the contact center is not in service. In these maintenance windows, one or more physical hosts may be out of service, including all the virtual machines running on these hosts.

Important:

  • Host maintenance must include consideration of all components of the customer solution. For example Avaya Analytics™, Avaya Breeze® platform and Avaya Oceana®. Refer to the relevant maintenance documents for each solution component:

    • The VMware host maintenance section in the Maintaining and Troubleshooting Avaya Oceana® manual.

    • The Upgrading Avaya Analytics™ ESXI hosts section in the Maintaining and Troubleshooting Avaya Analytics™ for Avaya Oceana® manual.

    • The Maintaining and upgrading ESXi host software section in the Maintaining and Troubleshooting Avaya Breeze® platform manual.

The following are important considerations when removing or adding physical hosts to the deployment:

  • Do not remove or replace the physical VMware ESXi hosts running Avaya Analytics™ virtual machines from the VMware cluster during maintenance windows.

  • You can add one or more physical hosts to the VMware cluster to facilitate host maintenance. Adding physical hosts enables migrating host virtual machines to a new host while the existing host is updated.

  • You must propagate all the VMware permissions for the same user account used to deploy the Avaya Analytics™ cluster to the new host. You must perform this before removing the new host from maintenance mode and putting it into production. Avaya Analytics™ virtual machines cannot access resources on the new host if you fail to propagate VMware permissions.
