Expanding Your System to a Larger System Size

Expanding Your System to a Larger System Size

Preparing for System Expansion

This section describes the prerequisites and best practices for a system expansion.

Determining Your System's New Size

Consider the following:
  • Budget for hardware
  • Number of concurrent meetings, and the average size of these meetings, for the next few months and years

Obtaining the Information Required For Your System Expansion

  • Obtain the OVA file used to install the existing system's version.
  • Complete the expansion checklist.

Preparing For a System-Altering Procedure

This section describes how to prepare for a major system-altering procedure: expanding your system, adding a high availability system, enabling public access, updating or upgrading your system, and so on.


Caution


Because this procedure requires exclusive access to the system, users cannot access the system for meetings. Be sure to schedule this procedure during a time that will be least disruptive to your users.

Other system administrators should not access the system during this procedure. If they do so, their changes are not saved, and the result may be unpredictable. They must wait until this procedure is completed, then sign in to Cisco WebEx Administration to do their task.


Note


Be sure to coordinate with other system administrators before starting a system-altering procedure.


Attention:

If you do not need to create a backup of your virtual machines, then you do not need to complete this procedure. However, as a best practice, Cisco recommends creating a backup. Backups enable you to revert the system if the procedure is unsuccessful.

Procedure
    Step 1   Sign in to the Cisco WebEx Administration site.
    Step 2   Select Turn On Maintenance Mode.
    Step 3   In the VMware vSphere client, power off each of the virtual machines in your system. Select Power > Shut Down Guest .

    For complete details on using vSphere, see the VMware ESXi and vCenter Server documentation.

    Step 4   Once all the virtual machines are powered off, then use VMware Data Recovery to create a backup of each of your virtual machines.

    A backup will help you revert your virtual machine to its state before the update. For further information, see Creating a Backup Using VMware vCenter. For complete details on this backup, see the VMware Data Recovery Administration Guide.

    Note   

    You may also take snapshots, but you must delete these in approximately 24 hours, or you may experience data performance issues, common to virtual machine snapshots. For more information, see Taking a Snapshot Using VMware vCenter.

    Step 5   In the VMware vSphere client, power on each of the virtual machines in your system.
    Step 6   Sign back in to the Cisco WebEx Administration site, but do not turn off maintenance mode.
    Step 7   Continue with the system-altering procedure.

    Expanding the System Using Automatic Deployment

    Before You Begin

    In this section, we refer to the system before expansion as the "existing system". The system, following expansion, is the "expanded system."

    • Schedule a time that is least disruptive to your users to do the system expansion.
    • Put the primary system in maintenance mode before starting the system expansion.

    Caution


    Because this procedure requires exclusive access to the system, users cannot access the system for meetings. Be sure to schedule this procedure during a time that will be least disruptive to your users.

    Other system administrators should not access the system during this procedure. If they do so, their changes are not saved, and the result may be unpredictable. They must wait until this procedure is completed, then sign in to Cisco WebEx Administration to do their task.


    Note


    Be sure to coordinate with other system administrators before starting a system-altering procedure.


    Expanding the System

    The overall tasks to expand the system are:

    1. Create a backup of your existing system.
    2. Use the same OVA file you used to deploy your existing system and deploy the Admin virtual machine for the new system size.
    3. Copy the data from your existing system to the Admin virtual machine for the expanded system.
    4. Deploy any additional virtual machines for the new system size.
    5. Test the expanded system.

    Considerations Before Expanding the System

    Note the following:

    • You may choose to reuse the same hostnames and IP addresses for the existing virtual machines in the expanded system. However, only the existing system, or the expanded system, can be powered on at any given time. Both systems cannot be powered on and running at the same time.
    • If you have already added a HA system to your existing system, then following deployment of the expanded system, you must add a new HA system. You cannot reuse the existing HA system as it is not retained, following the expansion.
    • You may want to keep the existing system until you have finished testing the expanded system. Once testing is complete and you are satisfied with the expanded system, you can remove the existing (pre-expansion) system.
    • The internal virtual machines for the existing system and the expanded system must be on the same subnet.
    • If you have added public access, then the Internet Reverse Proxy virtual machines for the existing system and the expanded system must be on the same subnet.
    • Because this process affects the virtual machines in your system, your current security certificate may become invalid and require an update.
    • Be sure the expanded system can access the disks for the existing system's Admin virtual machine. You will be copying over Hard disk 4 to the expanded system.

    Testing the System

    These are some of the tests to run on the system. You can accomplish these tests and validate your system by using two diagnostic tools provided on the support pages for this product: the Meetings Test and the System Resources test.

    • Add, edit, activate, and deactivate users.
    • Schedule and hold a meeting.
    • Reschedule an existing meeting.
    • Delete a series of meetings or a future meeting.
    • Open a meeting attachment.
    • Play a meeting recording.
