#Creating a Virtual Disk

Note: Virtual disks can be mounted online when the virtual machine is in running state.

#Procedures

1. Access the Container Platform.

2. In the left navigation bar, click on Virtualization > Virtual Disk.

   Parameter	Description
   Volume Mode	- File System: Mount the disk in a way that mounts the file directory. - Block Device: Mount the disk as a block device.
   Storage Class	The platform maintains virtual machine disks by automatically creating and managing persistent volume claims. You need to specify the storage class required for dynamically creating persistent volume claims. Different storage classes support different volume modes. If there are no available storage classes for the selected volume mode, please contact the administrator for addition.
   Delete with VM	If enabled, the disk data will also be deleted when the virtual machine is deleted.
   Mount	- Do Not Mount: Only create the virtual disk; it can be mounted later when needed. - Mount to VM: Select the target virtual machine to which the virtual disk needs to be mounted.
