1 Click Storage in the VMware Host Client inventory and click Datastores.
2 Right-click the datastore to unmount from the list and click Unmount.
3 Conrm that you want to unmount the datastore.
Unmounting or Removing Datastore Fails
When you try to unmount or remove a datastore, the operation fails.
Problem
The operation to unmount or remove a datastore fails if the datastore has any opened les. For these user
operations, the vSphere HA agent closes all of the les that it has opened, for example, heartbeat les. If the
agent is not reachable by vCenter Server or the agent cannot ush out pending I/Os to close the les, a The
HA agent on host '{hostName}' failed to quiesce file activity on datastore '{dsName} fault is
triggered.
Cause
If the datastore to be unmounted or removed is used for heartbeating, vCenter Server excludes it from
heartbeating and chooses a new one. However, the agent does not receive the updated heartbeat datastores
if it is not reachable, that is, if the host is isolated or in a network partition. In such cases, heartbeat les are
not closed and the user operation fails. The operation can also fail if the datastore is not accessible because of
storage failures such as all paths down.
N When you remove a VMFS datastore, the datastore is removed from all the hosts in inventory. So if
there are any hosts in a vSphere HA cluster that are unreachable or that cannot access the datastore, the
operation fails.
Solution
Ensure that the datastore is accessible and the aected hosts are reachable.
Using Datastore File Browser in the VMware Host Client
Use the datastore le browser to manage the contents of your datastore. You can perform a number of tasks
that include uploading les to the datastore, downloading datastore les to your system, moving and
copying datastore folders or les, and creating new datastore directories.
Upload Files to a Datastore in the VMware Host Client
Use the datastore le browser to upload les to datastores on your host.
N Virtual Volumes do not support uploading les directly to the virtual datastores. You must rst
create a folder on the virtual datastore, and then upload the les into the folder.
In addition to their traditional use as a storage for virtual machine les, datastores can serve to store data or
les related to virtual machines. For example, you can upload ISO images of operating systems from a local
computer to a datastore on the host. You then use these images to install guest operating systems on the new
virtual machines.
