When is it possible to place a VMFS5 datastore in maintenance mode?
A. When it is a member of a Storage DRS cluster
B. When it is a member of Virtual SAN cluster
C. When it is a member of a multi-extent datastore
D. When it is a member of a Virtual Volume
Correct Answer: A
Explanation/Reference:
Explanation:
Storage DRS introduced the feature Datastore Maintenance mode and this new feature can be compared to Host Maintenance Mode. When a datastore is placed in Maintenance Mode all registered virtual machines on that datastore, are migrated to the other datastores in the datastore cluster.
Datastore maintenance mode can be used to safely migrate virtual machines out of the datastore for storage array related maintenance operations such as migrating a LUN to another RAID group, however it is also an excellent feature that can help you during a storage migration project migrating virtual machines from standalone VMFS3 datastores to VMFS5 datastores aggregated in a Storage DRS datastore cluster.
