Adding a disk to a virtual server will require that VS should 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:
Move the slider to the right to specify the desired disk size.
The disk size should not exceed 2 TB when a new disk is added. You can later resize the disk if you need it to be larger than 2 TB.
Click the Add Disk button to finish.
For primary and swap (Linux, FreeBSD) disks you may only change the label and the size.
You can easily resize disks when needed. The resize will fail if your current usage is greater than the new size you request. Note, that any changes on disk size will lead to reboot of your VS.
To change disk size:
You can migrate disks of your virtual servers to other data stores, which are allocated to the same Compute resource. Unlike VS migration – disk migration requires reboot of the VS (despite the template it is based on).
To migrate a disk:
On the screen that appears, select a target data store from a drop-down box.
Click Start Migrate.
To delete a disk:
Move the Required Startup slider to the right to start up the VS automatically.
Steps 5 and 6 apply to disks of VSs that are on.
Click the Destroy Disk button.
This will schedule the "destroy disk" transaction.
