Manage vCloud Director VS Disks

Virtual server storage is provided by disks. A disk is a partition of a data store that is allocated to a specific virtual server. This section provides the information on all the actions supported for disks imported from your vCloud Director. 


View Disk Details



To view disk details:

  1. Go to Control Panel Virtual Servers menu.
  2. Click the Label of an appropriate virtual server.
  3. Go to the Storage tab and click Disks.
  4. Click the Label of an appropriate disk. On the screen that appears, you will see the disk identifier, size in GB and bus sub type.


Create Disk



Adding a disk to a virtual server will require that VS to be rebooted. If a VS is running when you try to add a new disk to it, you'll be asked to confirm the reboot. To add a disk to a virtual server:

  1. Go to your Control Panel > Virtual Servers menu.
  2. Click the Label of an appropriate virtual server.
  3. Click the Storage tab > Disks.
  4. Click the Create Disk button.
  5. Fill in the details:
    • Data Store - select the data store to which the disk will be assigned

    • Size - enter the disk size

    • Bus Sub Type - select the sub type of 'scsi controller' to create the disk on. For more information, refer to VMware documentation.
  6. Click the Add Disk button to finish.

When you add a new disk to a virtual server, it will automatically become available to that server.


Edit Disk



You can resize the disk or live migrate it to another data store by following the next steps: 

  1. Go to your Control Panel > Virtual Servers menu.
  2. Click the Label of an appropriate virtual server.
  3. Click the Storage tab > Disks.
  4. Click the Actions icon next to the disk that you want to modify and click the Edit button.
  5. In the pop-up window change the required parameters:
    • Label - enter a new label for the disk
    • Size - move the slider to select a new size for the disk in GB
    • Data Store - select a new data store for the disk 
    • Hot migrate disk - turn the switcher to the right to run hot (live) migration of the disk to the destination data store

      If you migrate the disk without the Hot migrate disk option enabled, the virtual server will be rebooted. You will be asked for confirmation to reboot the virtual server.

  6. Click the Save Disk button.
  • If fast provisioning is enabled for the disk resource pool, the disk cannot be resized.
  • You cannot decrease the size of disk(s).
  • If you resize the disk of a VS that is powered on, the virtual server will be rebooted. You will be asked for confirmation to reboot the virtual server.
  • You can only migrate disks to data stores in data store zones assigned to your bucket
  • You cannot migrate a disk to a data store with less capacity than the disk size.
  • If required, you can change a block size which is used during the disk migration at Control Panel > Settings > Configuration > System by editing the Block Size (MB) parameter.
