Install Changes Since UC 2.x
 Unity Connection 7.0 2 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.

Cluster Installation,
when not running an ES on publisher
To install a Unity Connection Active/Active pair do the following:
1) Install the CUC 7.0 publisher/“first-node” server if one has not already been
installed.
2) Log into the CUC System Administration interface and navigate to the Cluster
configuration page (in left-hand tree control System Settings -> Cluster).
3) Add the hostname for the subscriber server that will be installed.
4) Boot the new subscriber server to installation using the full install media for the
version currently running on the publisher.
5) Complete the installation dialogs as normal, with the exception of when asked if
this is a “first-node” answer No.
6) Complete the required subscriber installation information such as the publisher
server name, publisher IP address, and the security password used on the
publisher.
7) After subscriber installation completes you are ready to upload licenses, install
locales, and configure ports etc.
Note: CUC Active/Active pairs register to different port groups, and call distribution is handled by
the IP PBX (UCM), unlike enterprise Unity failover model.

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.

Clusters and Locales
Locales are still installed from .cop files as they were in Unity
Connection 2.x.
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.

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).

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…

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.

Reduced ES iso Upgrades
 Full isos have a file name like UCSInstall_UCOS_7.0.1.10005.sgn.iso, and these files can be used for fresh installs.
 Reduced ES upgrades have a file name like
UCSInstall_UCOS_ES_7.0.1.1000-5.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.

Cluster Upgrades
 You must upgrade the publisher before the subscriber upgrade.
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.

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 <filename>.
 The first installs log is named install.log. Upgrade and optional
package install logs are named install_log_<year>-<month#><day>-<hour>-<min>-<second>.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.
