You are planning a vSphere 4.1 to 5.0 upgrade. The production datastores are 6 TB. Each
datastore consist of thee extents of 2 TB and is currently 65% full. The operations team would like
to keep the system as close to the current configuration as possible. The upgrade process also
requires as little service impact as possible. In addition, you wish to use storage I/O control as
soon as possible, due to a mission-critical business application requirement. Which of the
following would be the correct approach?
A.
Create a new VMFS 5 datastore of 6 TB
Enable storage I/O control
Migrate the VMs using storage vMotion
Configure storage I/O shares as required
B.
Upgrade the VMFS 3 datastore
Enable storage I/O control
Configure storage I/O shares as required
Explanation:
When a datastore with VMFS v3 is upgraded with extents to VMFS v5, the logical attributes
andextents are not changed. Storage I/O control cannot be used with datastores composed of
extents.
