Steps to re-image a UCX Release 6.0 operating with HARC (High Availability) to UCX Release 7.0 are as follows:
There is no mechanism to re-image a UCX Release 6.0 system running in HARC mode to be re-imaged to UCX Release 7.0 directly. Follow the steps for Splitting a Cluster during initial configuration as documented in High Availability - Web-based Configuration Utility Rls 6.0.
After the cluster is split, both of the systems will be accessible via their originally assigned IP addresses and the Cluster IP address will not be assigned to anything.
The devices like IP telephones, DSM16s, FXS16s, PRI cards, IP Trunks, or third party gateways are programmed to connect to the Cluster IP address. Once you have split the cluster, communication with any of the devices and interfaces will be temporarily interrupted. Therefore, E-MetroTel recommends that you reassign the cluster IP address to one of the nodes that is still running UCX Release 6.0 to temporarily maintain service during the maintenance window.
This system will become the "active" system.
You only need to do this on one system as both systems will be identical after running in HARC mode. Note that if you have a system with redundant hard drives, you may temporarily remove one of the drives as this would already contain a full system backup.
Follow the standard update procedures to update the "inactive" system (the one without the Cluster IP address) to UCX Release 7.0 outlined in sections 1 to 6 of this document (Release 7.0 Update Process). This includes updating the system with the latest updates, retrieving the new Release 7.0 licenses, and installing any required add-ons (including the High Availability add-on).
After verifying the update is complete, you may wish to make another backup of the active system and use this newly created Release 6.0 backup when restoring the database on the inactive system as part of step 5.6 Restore the original Telephony Configuration of described in 5.0 Completing the Reimage to UCX 7.0 Process.
You can now temporarily assign the Cluster IP address to the newly re-imaged Release 7.0 system. This will allow service to be temporarily maintained while re-imaging the second system.
Follow the standard re-image procedures to re-image the remaining UCX Release 6.0 system (the one without the Cluster IP address) to UCX Release 7.0 outlined in sections 1 to 6 of this document (Release 7.0 Update Process). This includes updating the system with the latest updates, retrieving the new Release 7.0 licenses, and installing any required add-ons (including the High Availability add-on).
On this sytem, however, DO NOT restore the database.
At this point in time both systems are re-imaged and ready to be re-configured for the High Availability (HARC) configuration. To configure HARC, follow the steps identified in High Availability - Installation and Configuration Rls 7.0.
Once the cluster is created, the two systems will synchronize and the HARC configuration is complete.
Refer to 6.0 Completing the Update to InfinityOne 4.0 for steps to update InfinityOne to Release 4.0. This can be completed while the two nodes are synchronizing.
