2V0-622 Question #150: Real Exam Question with Answer & Explanation

The correct answer is A. Set the Storage DRS advanced option IgnoreAffinityRulesForMaintenance = 1. C. Disable Storage DRS affinity rules associated with this datastore cluster.. When Storage DRS attempts to place a datastore into Maintenance Mode, it must evacuate all VMs by migrating their VMDKs to other datastores in the cluster using Storage vMotion. If VM-VM affinity rules or VM-datastore affinity/anti-affinity rules prevent those migrations (e.g., a

Question

An administrator attempts to place a Storage DRS enabled Datastore into Maintenance Mode. The task never completes, and the Entering Maintenance Mode status remains at 1%. Which two actions should the administrator take to resolve this problem? (Choose two.)

Options

ASet the Storage DRS advanced option IgnoreAffinityRulesForMaintenance = 1.
BSet the Storage DRS advanced option IgnoreAffinityRulesForMaintenance = 0.
CDisable Storage DRS affinity rules associated with this datastore cluster.
DEnable Storage DRS affinity rules associated with this datastore cluster.

Explanation

When Storage DRS attempts to place a datastore into Maintenance Mode, it must evacuate all VMs by migrating their VMDKs to other datastores in the cluster using Storage vMotion. If VM-VM affinity rules or VM-datastore affinity/anti-affinity rules prevent those migrations (e.g., a rule requires two VMs to keep their disks on the same datastore, but no other single datastore can accommodate both), the process stalls - hence the task remaining at 1%. (A) Setting the Storage DRS advanced option IgnoreAffinityRulesForMaintenance = 1 instructs Storage DRS to override and ignore affinity rule constraints specifically during a maintenance mode evacuation, allowing migrations to proceed even if they temporarily violate affinity rules. (C) Manually disabling the conflicting affinity rules removes the constraint entirely, freeing Storage DRS to migrate VMs without restriction. Option B (setting the value to 0) is the default behavior that respects affinity rules, which is the very cause of the problem, so it would not help. Option D (enabling affinity rules) would add more constraints, worsening the blockage.
