An administrator has configured a vSphere 5.5 test environment to evaluate the Virtual SAN feature using Automatic Mode Disk Groups. The administrator needs to disable the Virtual SAN cluster while preserving the virtual machines running on that cluster.
The administrator has already installed a vSphere 5.5 Client on a Windows 7 desktop and also has access to the vSphere 5.5 Web Client.
What should the administrator do to disable the Virtual SAN?
A. Use Storage vMotion to migrate the virtual machines to another datastore then use the vSphere 5.5 Client to disable the Virtual SAN.
B. Use Storage vMotion to migrate the virtual machines to another datastore then use the vSphere 5.5 Web Client to disable the Virtual SAN.
C. Use the vSphere 5.5 Client to disable the Virtual SAN, which will automatically migrate the virtual machines via the Storage DRS feature.
D. Use the vSphere 5.5 Web Client to disable the Virtual SAN, which will automatically migrate the virtual machines via the Storage DRS feature.
Correct Answer: B
Explanation/Reference:
Explanation:
In this question, we have virtual machines (VMs) running on a Virtual SAN cluster. To disable the virtual SAN cluster without affecting the VMs, we first need to move the VMs to different storage. The process of moving VMs from one SAN to another is known as Storage vMotion. After the VMs have been moved, we can disable the virtual SAN cluster.
When you disable the Virtual SAN cluster, all virtual machines located on the shared Virtual SAN datastore become inaccessible. If you intend to use the virtual machines while the Virtual SAN is disabled, make sure you migrate virtual machines from the Virtual SAN datastore to another datastore before disabling the Virtual SAN cluster.
To disable a Virtual SAN:
Browse to the host cluster in the vSphere Web Client navigator.
Click the Manage tab and click Settings.
Under Virtual SAN, select General and click Edit.
Deselect the Turn On Virtual SAN check box.
Incorrect Answers:
A: We need to use the vSphere 5.5 Web Client to disable the Virtual SAN, not the vSphere 5.5 Client. Therefore, this answer is incorrect.
C: We need to use the vSphere 5.5 Web Client to disable the Virtual SAN, not the vSphere 5.5 Client. Furthermore, Virtual SAN does not support Storage DRS so the VMs will not be automatically migrated to different storage. Therefore, this answer is incorrect.
D: Virtual SAN does not support Storage DRS so the VMs will not be automatically migrated to different storage. Therefore, this answer is incorrect.
