| Outline the steps to create a VMFS Datastore |
|
Definition
Go to the vSphere Client, select your host and go to the configuration tab.
Click 'Add Storage'
Select the disk/LUN storage type as VMFS and the desired device and file-system version.
Select whether to use all available partitions (erase everything) or only free space. If you are adding a blank disk then you would only see the entire space.
Name your datastore. |

|
Term
| When you create a new VMFS datastore on a host that is part of the cluster, where is the rescan operation performed? |
|
Definition
| On all hosts in the cluster |
|
|
Term
| How do you rename a VMFS datastore? |
|
Definition
| Right click on the datstore and click 'rename' |
|
|
Term
| How do you delete a VMFS datastore? |
|
Definition
1. Remove all VMs from the datastore
2. Right click and select 'Delete'
IMPORTANT: once you delete the datastore, it will be gone from all hosts and all data on it will be destroyed |
|
|
Term
| T/F: Unmounting a datastore destroys all data on the datstore |
|
Definition
| False. Un-mounting a datastore simply removes that datastore from a host. It will remain visible to all other hosts that have access to it. |
|
|
Term
| What steps should you take before unmounting a datastore to avoid host failure? |
|
Definition
1. Ensure no operations are in progress to cause I/O on the datastore
2. Remove the datastore from datastore clusters
3. Disable storage I/O (if enabled)
4. Ensure the datastore is not being used for HA heartbeating |
|
|
Term
| How do you unmount a datastore? |
|
Definition
| Right click on the datastore and select 'unmount'. You need to specify which hosts to unmount from if the datastore is shared. |
|
|
Term
| What options do you have to increase the space on your VMFS datastore? |
|
Definition
1. Add a new extent
2. Grow an existing extent |
|
|
Term
| What steps do you take to extend or expand a VMFS datastore? |
|
Definition
1. Click on the datastore and go into 'properties'
2. Click 'increase' and select the option to add a new extent or grow an existing one
3. The process from here is similar to creating a new datastore |
|
|
Term
| T/F: Adding extents to a datastore negates your ability to use Storage I/O control for that VMFS datastore |
|
Definition
|
|
Term
| What happens to VMs on a VMFS datastore if you put the datastore in maintenance mode? |
|
Definition
| VMs will be evacuated by using storage vMotion to other datastores |
|
|
Term
| What pre-requisites must be met before placing a datastore in maintenance mode? |
|
Definition
1. Storage DRS needs to be enabled on the datastore cluster containing the datastore
2. No CD ROM/ISO images can be stored on that datastore
3. There must be at least 2 datastores in the cluster |
|
|
Term
| What steps are taken to place a datastore in maintenance mode once the pre-requisites for maintenance mode are met? |
|
Definition
| Select 'Enter SDRS Maintenance mode' from the datastore inventory view on the datastore you wish to bring into maintenance mode. You will receive placement recommendations and have the opportunity to select which to proceed with |
|
|
Term
| What path selection policy must be in place in order to set a preferred path for a VMFS datastore, what policy to disable a path? |
|
Definition
| The Fixed Path Policy must be in place to select a preferred path. Path selection policy does not matter for disabling a path - any policy can be in place. |
|
|
Term
| How do you set the preferred path for a VMFS Datastore, or disable a path to a VMFS datastore |
|
Definition
| Go into the Datastore View. Right click on the desired or undesired path and select 'Preferred' or 'Disabled' as applicable. |
|
|
Term
| T/F: VMFS 2 can be upgraded directly to VMFS 5 |
|
Definition
| False: If however you are in VMFS 2 you must perform the upgrade to VMFS 3 first (thus, since ESXi 5 cannot access VMFS 2 you will need to keep a legacy 4.1 host around to do this), then upgrade to VMFS 5 |
|
|
Term
| T/F: Upgrading VMFS can be performed while VMs are running |
|
Definition
| True. However, there are some situations where a complete reformat of your datastores would be preferred (if you weren't using a 1MB block size) |
|
|
Term
| T/F: Upgrades of VMFS from 2 to 3 or 3 to 5 are reversible |
|
Definition
| False: VMFS upgrades are a one way process |
|
|
Term
| What is the name of the new partition format used in VMFS 5? |
|
Definition
| GPT - the old version was MBR. |
|
|
Term
| What steps do you need to take to do an in-place upgrade of VMFS? |
|
Definition
1. Verify that the host has at least 2MB of free blocks and 1 free file descriptor.
2. Select the VMFS datastore from the Storage section of the Hosts Configuration Tab
3. Click 'Upgrade to VMFS 5' |
