Introduction
This document discusses on some of the common issues that occurs during the installation of Cisco Unity
Connection.
Refer to Cisco Technical Tips Conventions for more information on document conventions.
Q. What is the Hardware Design requirement for the deployment of Cisco
Unity Connection?
A. Each Cisco Unity Connection host is implemented as a virtual host on a Unified
Computing System platform under VMWare ESXi where B−Series UCS systems can be
configured for maximum redundancy. Each virtual Cisco Unity Connection instance is
mapped 1 to 1 with each physical UCS blade. The Cisco Unity Connection implementation
supports active−active pairs (Unity Connection Nodes) that consist of a primary and a
secondary server. Typically, each node is sized based upon a port to user ration of roughly
1:40 with a maximum of maximum of 20,000 users per node.
Q. To which account name must all root administrator and web
administrator accounts be set?
A. The account names for all root administrator and web administrator accounts must be set
to: ucmadmin
Note: This account name must be entered exactly as shown in all lower case letters.
Q. What are the different web administrative portals available for Cico
Unity Connection?
A. After the appliance server has been installed from the approved media, all standard
configuration tasks are completed through the web−based administrative interface. There are
five different web administrative portals available for Cisco Unity Connection:
1. Cisco Unified ServiceabilityUsed for controller service activation and SNMP
configuration.
2. Cisco Unified OS AdministrationUsed for OS configuration and administration.
3. Cisco Unity Connection AdministrationPrimary interface for Unity management.
4. Cisco Unity Connection ServiceabilityUsed for detailed control of Unity
Connection service functions. This interface is where a server can be taken out of
service.
5. Disaster Recovery SystemUsed to control enabling and configuration of required
system backups.
Q. What are the services that need to be activated in Cisco Unity
Connection?
A. Under the service activation section, four services in three categories aredisplayed. All
services displayed must be activated on both servers. The Cisco DirSync service is only listed
on the publisher.
Q. How to resolve the Write Cache is not supported on this
System error that occured during the installation of Cisco Unity
Connection 8.6 on the 7825 H3 Server?
A. A disabled write−cache on the server also causes the upgrade process to run more slowly.
Multiple factors, which includes dead batteries on older servers, can cause the write−cache to
get disabled.
Before you start an upgrade, verify the status of the write−cache on the MCS−7828−H4 and
MCS−7835/45 disk controllers. You do not need to verify the write−cache status on the
MCS−7816, MCS−7825, or other MCS−7828 servers. To verify write−cache status, access
the Cisco Unified Operating System Administration, and choose Show > Hardware.
Note: This example shows write−cache enabled. The example indicates that 50 percent of the
cache is reserved for write and 50 percent of the cache is reserved for read. If the write−cache
was disabled, 100 percent of the cache would be reserved for read or the Cache Status would
not equal OK. Also, the battery count equals 1. If the controller battery was dead or missing, it
would indicate 0.

Q. What is the supported platform list for Cisco Unity Connection 8.x?
A. Refer to Cisco UCS−C210M2 for more information.
Q. How do you resolve this error that appeared during installation of
Cisco Unity Connection?
The installation has encountered a unrecoverable internal error. For further assistance report th
A. If Cisco Unity Connection is installed in a virtual environment, make sure that the
requirements for virtualization have been reviewed and met. An attempt to install Cisco Unity
Connection in a non−supported virtual environment can result in performance degradation of
the product. If the installation is on physical bare metal hardware, check that hardware RAID
configuration is correct and that no hard drive errors or other issues are reported by BIOS or
other system components. This is documented in the Cisco bug ID CSCti73841.
If the issue is still not resolved, complete the instructions in Disable LRO in order to disable
the Large Receive Offload (LRO).
Q. Does Cisco Unity Connection 8.6 work with Microsoft Office 365?
A. Yes, Cisco Unity Connection 8.6 works with Microsoft Office 365. Refer to Configuring
Cisco Unity Connection 8.6(2) and later and Microsoft Office 365 for Unified Messaging for
more information on how to configure CUC 8.6 for Microsoft Office 365.
