You can view a vCMP™ application volume on the system, control the amount of physical disk space that the BIG-IP® system allocates to a vCMP volume, or delete a vCMP volume. The BIG-IP system creates a vCMP application volume when you initially provision the vCMP feature.
The way that you control the amount of disk space that the BIG-IP system allocates to a vCMP application volume is by using the Disk Management screens of the BIG-IP Configuration utility. More specifically, the Disk Management screens allow you to reserve an amount of disk space for other uses so that the system does not allocate all available disk resources to the vCMP application volume.
Sometimes, you might need to de-provision the vCMP feature to perform certain disk management tasks. For example, you might want to increase the amount of disk space that the BIG-IP system reserves for non-vCMP uses such as an additional installation location. In this case, you must first de-provision the vCMP feature, and then explicitly delete the vCMP application volume from the system, before increasing the reserve amount. Once you have increased the reserve amount, you can re-provision the vCMP feature, thereby creating a new vCMP application volume.
