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 Serviceability—Used for controller service activation and SNMP configuration.
  2. Cisco Unified OS Administration—Used for OS configuration and administration.
  3. Cisco Unity Connection Administration—Primary interface for Unity management.
  4. Cisco Unity Connection Serviceability—Used for detailed control of Unity Connection service functions. This interface is where a server can be taken out of service.
  5. Disaster Recovery System—Used 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.

Example 1 7835/45-H1, 7835/45-H2, 7828-H4 Servers with Write-Cache Enabled

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 the following information to your support provider.
Command "/opt/cisco/install/bin/pmNormalizeGeneric/etc/opt/cisco/install/component_install_cmd_list" 
has exceeded timed threshold of 3600 seconds
The system will now halt.
continuing will allow you to dump diagnostic information before halting.

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.
