Management of Virtual Machine Hosting an SD-WAN Control Component

Upgrade memory and vCPU resources on a virtual machine hosting Cisco Catalyst SD-WAN Manager

Only memory or vCPU increase is allowed. After the memory or vCPU is upgraded, you cannot downgrade.

Procedure

Step 1

Check the current configuration on Cisco SD-WAN Manager using the show system status command.

Expand the secondary disk size, Cisco Catalyst SD-WAN Manager Release 20.12.x and earlier

Before you begin

Ensure that you are on Cisco Catalyst SD-WAN Manager Release 20.12.x or earlier.

Due to a known limitation, this procedure is not effective for Cisco Catalyst SD-WAN Manager Release 20.13.x, 20.14.x, or 20.15.x.

Perform these steps to increase the size of the secondary disk on the virtual machine hosting a Cisco SD-WAN Manager instance.

Procedure

Step 1

Shut down the virtual machine hosting Cisco SD-WAN Manager .

Step 2

Using the hypervisor (for example, ESXi, Azure, or AWS), provision additional space for the secondary disk of the virtual machine hosting Cisco SD-WAN Manager .

Step 3

Restart the VM that is hosting Cisco SD-WAN Manager .

Step 4

In Cisco SD-WAN Manager, enter the following to enable Cisco SD-WAN Manager to detect the additional disk space and extend the file system to use the space. 

vm# request nms application-server resize-data-partition

Step 5

Enter the following commands to confirm that the /opt/data disk has been resized.

vm# vshell 
vm:~$ df -hk | grep data
The output shows the new disk size.
