How to increase hard disk space on a DCE VM

To increase storage for the VM, you must create additional hard disks. You cannot change the size of an existing hard disk or remove a hard disk once it has been created. An error will occur on the primary interface, and the DCE virtual appliance will not start.

1. Gracefully shut down the DCE virtual appliance: In the DCE desktop client, go to File > Shut down server.

2. In your vSphere (VMware) virtual server settings, select the option to add a hard disk.

   NOTE: Do not increase the size of the default drive (18GB for DCE 7.9.2 and older, 40GB for new installs of DCE 7.9.3 and newer) or any other previously allocated drives. The server will not see the newly added and it may cause storage issues. Once the DCE VM boots with a new drive, it allocates the space for the database on that drive and will not re-allocate space if the drive size is increased. ALWAYS add a new drive when increasing drive space for the DCE VM.

3. Choose the hard disk size. For physical appliance equivalents, see Data Center Expert server equivalent configurations for VM

4. Choose thin or thick provisioning.

5. Power on the virtual appliance.
   
   NOTE: Changes in the disk space will take effect once the Data Center Expert virtual appliance has restarted. Do not shut down the virtual appliance while the disk reconfiguration process is running.
   
   TIP: To verify that the Data Center Expert Virtual Appliance sees the additional space, go to the DCE desktop client System > Server Administration Settings > Storage Settings option. The local repository option shows the combined amount of all of the disks added to the virtual appliance.
   
   NOTE: To store large amounts of surveillance data, using a remote repository is recommended.
