Configuring CPUs, Memory and Drive Space in a Microsoft Hyper-V Environment

Pre-Requisites

  • Microsoft Server 2012 R2 (Hyper-V)
  • Microsoft Remote Desktop and credentials to access the Hyper-V Environment
  • UCx Server Deployed in this Hyper-V Environment
  • The UCx Virtual Server MUST be Powered off to execute these changes 

Procedure

Step 1

Login to the Hyper-V Management Console.

Step 2

Right mouse click on the server to be modified and select Settings.

Step 3

This dialogue will allow you to make changes to your UCx Virtual Server.

Step 4

To adjust the memory.

WARNING - DO NOT REDUCE THE AMOUNT OF MEMORY TO LESS THAN 1536 MBytes.

Step 5

To increase the number of CPU's.

WARNING - DO NOT REDUCE THE NUMBER OF CPU"S TO LESS THAN 2

Step 6

To Increase the space available to the /var partition which is used for storing Voicemails and Call Recordings, Press the Edit button.

Step 7

Please read and observe the warnings, then press the Next button.

Step 8

Select Expand as the action to perform.

Step 9

Set the New size.

Step 10

Review your modifications.  Then press the Finish button.

Step 11

To complete the re-sizing of the disk drive you must power on the UCx Server.  Right mouse click on the Server and select Start.

Step 12

To connect to the console, right mouse click on the Server and select Connect.

Note: The UCx VM network interface is set by default to DHCP Client mode and will receive an IP address from the DHCP Server.

Step 13

Use the IP address displayed on the console to login to the UCx Sever instance and navigate to the Dashboard.

Step 14

Note that the size label of the /var partition in the Hard Drive applet on the dashboard is now a Blue hyperlink.

Step 15

When you select it, a dialogue box is displayed describing the increase in drive space that will occur, a warning that the system will be rebooted and asking for confirmation to continue with this process.

Step 16

Press the OK button.  Wait 30 seconds and then open the console window as described in Step 12 above.  Please allow the resize2fs command to complete before logging into the system GUI.

Step 17

One final step is to record the MAC address assigned to eth0.  You will need this information to move the UCx server instance from host to host within the Hyper-V environment.

Please note that if the MAC address of your virtual system is changed, then the license will become invalid. You will have to request for a new license whenever there is a MAC address change.
