Resource Reservation
The Resource Reservation has been enabled for all the three Unified CCX Profiles wherein any one of the Unified CCX Profile can be deployed through the single OVA. The Unified CCX 8.5(1) and 9.0(1) has been successfully qualified with vCPU reservations at 900 MHz per vCPU.
Resource reservation helps us to achieve the most optimum levels of utilization of underlying physical resources of ESXi 4.1 and ESXi 5.0 qualified Cisco/HP/IBM servers either when Unified CCX VM has been deployed with multiple instances of other Unified CCX VM or co-resident with any other Unified Communications application VMs on the same server.
The resource reservation helps the user to confine the VMs to respective resources and also helps to achieve the highest possible level of utilization of underlying physical resources as long as the sum of all the VM resources are not oversubscribed.
Unified CCX or IPIVR-Specific VM Installation Information
Migrating and upgrading Unified CCX from physical to virtual server
To migrate and upgrade Unified CCX from a physical server to a virtual server, you can follow either of the following paths.
Note - Only virtual servers are supported from Unified CCX release 10.0.
For more information on supported upgrade paths, see Software and Hardware Compatibility Guide for Cisco Unified CCX and Cisco Unified IP IVR, available here: http://www.cisco.com/en/US/products/sw/custcosw/ps1846/products_device_support_tables_list.html
Pre-migration checklist
Complete the following steps before you start migration:
1. Run utils create report platform command and obtain the platformConfig.xml for the existing nodes.
2. Go to http://www.cisco.com/web/cuc_afg/index.html to access the Answer File Generator.
3. Enter the information for appropriate fields referring the platformConfig.xml. Password is encrypted, enter the decryted password.
4. Click Generate Answer Files to get platformConfig.xml and license MAC.
5. Make a note of the license MAC that is displayed.
6. Get the rehosted license.
a. Go to https://tools.cisco.com/SWIFT/LicensingUI/Home .
b. Click Transfer > License for Rehost-initiate.
c. Select the licenses to transfer and click Next.
Note - If the licenses are not displayed in the table. Specify the device details. For more information, see the video "How to Rehost and RMA Licenses", available
here: https://tools.cisco.com/SWIFT/LicensingUI/Home.
d. Enter the new MAC address and click Next.
e. Enter the email details to receive the re-hosted license and click Submit.
7. (Path 2) Before you remove the second node, archive the recordings. See "Exporting Recordings From CAD" section of Cisco CAD Installation Guide, available
here: http://www.cisco.com/en/US/products/sw/custcosw/ps1846/prod_installation_guides_list.html
Note - Unifed CCX stores 2.6 GB of recordings on the first node and 2.6 GB on the second node. If you choose Path 2 then the recordings on the second node are lost.
Migrating Unified CCX
Complete the following steps to migrate Unified CCX from a physical server to virtual server:
| Task | Reference |
|---|---|
| Backup Unified CCX on bare metal server and store the backup TAR file at a safe SFTP network location. Shutdown the server. | See "Backup and Restore" section of Cisco Unified Contact Center Express Operations Guide, available here: http://www.cisco.com/en/US/products/sw/custcosw/ps1846/prod_maintenance_guides_list.html |
|
Install ESXi on any one of the Unified CCX Supported Hardware for Virtualization. | Check for the supported ESXi versions before installation. |
| Deploy virtual machines from the templates. | See Readme with the Unified CCX virtual machine template. |
| Install the same version of Unified CCX on the virtual machine with the same network and platform settings of the baremetal server. |
See "Unified CCX Installation" section of Cisco Unified Contact Center Express Installation and Upgrade Guide, available here: http://www.cisco.com/en/US/products/sw/custcosw/ps1846/prod_installation_guides_list.html For unattended installation, see the "Perform Unattended Installation Using Answer File Generator" section of the Cisco Unified Contact Center Express Installation and Upgrade Guide. |
| Restore the first node from DRS backup. | See "Backup and Restore" section of Cisco Unified Contact Center Express Operations Guide, available here: http://www.cisco.com/en/US/products/sw/custcosw/ps1846/prod_maintenance_guides_list.html |
| (Path 1) Re-install second node
and (Path 1) Restore second node. | To re-install, second node, see "Unified CCX Installation" section of Cisco Unified Contact Center Express Installation and Upgrade Guide, available here: http://www.cisco.com/en/US/products/sw/custcosw/ps1846/prod_installation_guides_list.html
|
| | To restore second node, See "Backup and Restore" section of Cisco Unified Contact Center Express Operations Guide, available here: http://www.cisco.com/en/US/products/sw/custcosw/ps1846/prod_maintenance_guides_list.html |
| (Path 2) Remove second node. | To remove second node,

Upgrading Unified CCX
To upgrade Unified CCX, see "Unified CCX Upgrade" section of Cisco Unified Contact Center Express Installation and Upgrade Guide, available here: http://www.cisco.com/en/US/products/sw/custcosw/ps1846/prod_installation_guides_list.html
Steps to increase RAM after upgrade (L2 and RU) in 10.0(1)
You will receive the following error message when you login to the Unified CCX Administration page, If you perform an L2 (Linux to Linux) or RU (Refresh Upgrade) upgrade to 10.0(1) from a previous version:
"Error: VM configuration does not match the OVA profile. Please refer to the Unified CCX Virtualization DocWiki for the supported configurations."
Perform the following procedure to resolve the error:
- Gracefully shutdown the Unified CCX server.
- Increase the vRAM size as per the above table for 10.0(x).
Note: Do not perfrom any changes to the existing vDisk.
- Power-on the Unified CCX server.
New Identity Support for Unified CCX or IPIVR 9.0(2)
Use this feature to quickly deploy new instances of Unified CCX.
In the current version, using this procedure you can deploy Publisher Node/First Node of a Unified CCX cluster only. Install the Subscriber Node/Second Node using the standard installation procedure.
Perform the following procedure to create the new identity:
- Use the correct OVA to create a new VM for the Unified CCX virtual machine.
- Use the standard installation process to install the Unified CCX product.
- After the installation, do not perform any configuration. Convert the VM into a template.
- Use that template to create a new virtual machine instance.
- Power on the VM.
- Use the Answer File Generator tool (http://www.cisco.com/web/cuc_afg/index.html) to create a platformConfig.xml file.
- Insert the XML file into a virtual floppy instance (for directions, see http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1739).
- Mount the .flp file in the floppy drive of the new VM.
- Log in to the CLI of the VM (using the console or SSH) and run the command “utils import config”. The system reboots and restarts with the new identity.
