All rights reserved.Cisco ConfidentialPresentation_ID 3 Install Changes Since UC 2.x  Unity Connection server cluster installations (“Active/Active pair”) CUC Active/Active pairs help achieve redundancy as well as higher voice port capacities. CUC Active/Active pairs are essentially mirrored servers, so message storage capacity is not increased in an Active/Active pair. Locales and Clusters.  U1 Installations (“upgrade during install”) Needed for subscriber server replacement when a cluster is running a reduced ES version.

All rights reserved.Cisco ConfidentialPresentation_ID 10 Unity Connection Cluster Installation, When Pub is Running an ES Version, (“The U1 Subscriber Install”) To install a Unity Connection Active/Active subscriber when the publisher (“first-node”) is running an ES version:  Before starting the subscriber installation place the ES.iso file on an FTP or SFTP server that can be reached by the subscriber server during installation.  The same instructions as described previously would be followed with the following exceptions: Step 4) ES Difference: Since there would not be full install media available for the ES version you would boot the new subscriber server using a full 7.0 install media older than the target ES version. Before Step 5) ES Difference: When asked if you would like to apply a patch during installation answer yes, and provide FTP or SFTP server information and ES file location. All other steps are exactly the same as the normal subscriber install.

The locale installation is still performed through either the OS administration web interface (Software Upgrades -> Install/Upgrade), or through the CLI interface (“utils system upgrade initiate”). The only special consideration for running locales in a cluster is that the locale must be manually installed on both servers in the Active/Active pair.

© 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 14 Upgrades Methods  Upgrading through OS Web Page  Upgrading through the CLI

© 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 15 Upgrading through the OS Web Page  Use the navigation drop down to select Cisco Unified OS Administration and log in with platform admin credentials.  Navigate to Software Upgrades -> Install/Upgrade  Fill in required software location fields and click Next. If it is an upgrade via SFTP the iso will be downloaded.  An md5sum is calculated for the media and presented for the customer to verify it matches what was listed on the download site.  The admin selects whether it should upgrade, and immediately reboot to the new version after upgrade completes, or not (manually running the version switch at a later time / off hours).

© 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 16 Upgrading from the CLI  From the CLI (ssh session or console) run the command utils system upgrade initiate  Complete the CLI upgrade dialogs asking for the upgrade location, etc. The process is the same as the web upgrade, but text dialog based…

All rights reserved.Cisco ConfidentialPresentation_ID 17 Version Switch  Version switch is where data migration between versions happens, on systems with lots of data it can take over an hour.  Once the version switch data migration completes the server will reboot.  Version switch can be ran from the OS administration web page under Settings -> Version, and clicking Switch Version  Version switch can also be ran from the CLI command utils system switch-version  In a UC cluster the publisher version switch can be ran either before, or after, the subscriber node has been upgraded.

© 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 18 Reduced ES iso Upgrades  Full isos have a file name like UCSInstall_UCOS_ sgn.iso, and these files can be used for fresh installs.  Reduced ES upgrades have a file name like UCSInstall_UCOS_ES_ sgn.iso, and can only be used if you are on a recent enough version.  The admin runs an ES upgrade in the same way as a full upgrade.  ESs are much smaller, generally about half the size of the full ~2.7gb install media. They are smaller because they only contain RPMs that contain changes since the last “point” version.

Switching version on the publisher can happen either before, or after, a subscriber version switch.  The publisher must be running during a subscriber upgrade.  U1 upgrades have been introduced to support clustering.

All rights reserved.Cisco ConfidentialPresentation_ID 20 Installation and Upgrade Logs  Install and upgrade logs are physically located on the /common partition (/common/log/install/)  Upgrade logs can be gathered via RTMT (“install logs” in the log/trace gathering tool), or via the CLI commands file list install * and file get install.  The first installs log is named install.log. Upgrade and optional package install logs are named install_log_ log  If a critical error occurs that prevents installation or upgrade that error is logged by itself in the file critical.log, as well as the larger install log.
