Detaching a Volume from a Virtual Machine
Detach a volume to disconnect it from a virtual machine and keep it for future use, or attach it to another virtual machine as described in Attaching a Volume to a Virtual Machine. (You can also permanently delete the volume from the everRun system, as described in Removing a Volume from a Virtual Machine.)
Notes:
- When you detach a volume from a VM, both the volume and its volume container exist separately from the VM. They remain on the system even if you remove the VM.
- If you decide to remove the volume, and you also want to remove its volume container to reclaim space in the storage group, you must remove any snapshots stored in the volume container; otherwise, the volume container remains on the system. For more information, see Removing a Volume from a Virtual Machine.
- If you detach a boot volume from a VM, you cannot boot the VM; however, you might want to detach the boot volume to diagnose a boot problem or data corruption in the volume. You can temporarily attach the boot volume to another VM as a data volume, as described in Attaching a Volume to a Virtual Machine. After using guest operating system tools to resolve the issue, detach the volume and reattach it to its original VM.
Prerequisite: Before detaching a volume from a virtual machine, you must shut down the virtual machine.
To detach a volume from a virtual machine
- Open the Virtual Machines page (see The Virtual Machines Page).
- Select a VM and click Shutdown.
- When the VM has stopped, click Config to display the Reprovision Virtual Machine wizard.
- Click Next on each wizard page until the Volumes page is displayed. (If applicable, see Reprovisioning Virtual Machine Resources to configure additional VM resources.)
- On the Volumes page, locate the volume to detach. (If the volume is not visible, scroll down on the wizard page.)
-
Click Detach beside the volume name to mark the volume for detachment.
Caution: Be careful to mark the correct volume to detach, avoiding any volumes that are currently in use.
- Click Next on each wizard page until the Configuration Summary page is displayed. Verify the configuration changes.
- Click Finish to detach the selected volume.
