Issue/Introduction

You have a Management Center (MC) Virtual Appliance (VA) and  want to add extra disk space.

 

Environment

Management Center Virtual Appliance

Resolution

MC VAs have two disks, a boot disk and data disk.

Increasing the size of the boot disk (disk 1) or adding another virtual disk to an existing MC VA is not supported.

In releases prior to MC version 3.2, increasing data disk space on an existing MC VA required restoring defaults to utilize the extra space.

In MC versions 3.2.x and later, expanding the data disk space utilizing the storage command doesn't require restoring to defaults.

The storage command only applies to adding data disk space (disk 2).   

If your boot disk (disk 1) has less than the recommended 4 GB of disk space, deploy a new MC  instance following the Management Center Virtual Machine Sizing Guidelines.  

Backup MC and offload the backup to another file server (or download it to your desktop) before performing any maintenance on your MC.

To increase disk space for data disk (disk 2):

1. Backup MC and download the backup.
2. Power-off  MC
3. Increase the disk space on disk 2 (Refer to your Host Virtualization documentation on how to increase disk space in VM guest). 
4. Optional: Increase the number of CPUs and expand Memory if needed.  See Management Center Virtual Machine Sizing Guidelines for more information.
5. Power-on MC
6. Once booted, run the following commands in MC CLI privileged (enable) mode:

#storage view

#storage activate-extra-space

Note: Increasing the number of CPUs and expanding memory is automatically recognized by MC after a power cycle.  No additional commands are needed.
