Which action should an administrator take to increase the size of a VMFS5 datastore from 2TB to 32TB?
A. Dynamically expand the original LUN and add a second share for the NFS datastore
B. Dynamically expand the original LUN and increase the size of the VMFS datastore
C. Dynamically expand the original LUN and add extents to the VMFS datastore
D. Dynamically expand the original LUN and add extents to the NFS datastore
Correct Answer: B
Explanation/Reference:
Explanation:
A VMFS datastore resides on one or more extent. There must be only one extent per LUN. The first step is to expand the LUN that contains the datastore. This will create additional space after the current datastore extent. You can then expand the datastore which will expand the existing extent.
The default size for the expanded extent will be all the available space but you can enter a specific size if required.
This is the procedure to expand a datastore:
In vCenter Server, select the Datastores view.
Select the datastore you want to grow and identify the host that has more virtual machines running on it.
Open another vSphere client that connects directly to the ESX host.
Go to Configuration > Storage adapters and perform a rescan.
Go to Configuration > Storage, click the datastore that you want to grow, and click Properties.
Ensure that the new size of the device is listed in the Extent Device list. If the increased size is not reflected, review the changes on the storage array and rescan again.
Click Increase.
Select a device from the list of storage devices for which the Expandable column is Yes and click Next.
Set the capacity for the extent. The default capacity for the extent is the entire free space on the storage device. VMware recommends you to use the default setting.
Click Next.
After the process completes, go to vCenter Server, right-click the cluster that sees the expanded datastore, and click Rescan for Datastores..
If there are other hosts that see the expanded datastore, perform a rescan on these hosts also.
Incorrect Answers:
A: We need to expand a VMFS5 datastore. This has nothing to do with an NFS datastore. Therefore, this answer is incorrect.
C: It is not necessary to add extents to the VMFS datastore. With vSphere 5.5, you can dynamically expand an existing extent up to a maximum of
D: We need to expand a VMFS5 datastore. This has nothing to do with an NFS datastore. Therefore, this answer is incorrect.
