Suggested Answer: AB 🗳️
Datastore Cannot Enter Maintenance Mode
You place a datastore in maintenance mode when you must take it out of usage to service it. A datastore enters or leaves maintenance mode only as a result of a user request.

Problem -
A datastore in a datastore cluster cannot enter maintenance mode. The Entering Maintenance Mode status remains at 1%.

Cause -
One or more disks on the datastore cannot be migrated with Storage vMotion. This condition can occur in the following instances.
✑ Storage DRS is disabled on the disk.
✑ Storage DRS rules prevent Storage DRS from making migration recommendations for the disk.

Solution -
✑ If Storage DRS is disabled, enable it or determine why it is disabled. See Storage DRS is Disabled on a Virtual Disk for reasons why Storage DRS might be disabled.
✑ If Storage DRS rules are preventing Storage DRS from making migration recommendations, you can remove or disable particular rules. a In the vSphere Client inventory, right-click the datastore cluster and select Edit Settings. b Select Rules and click the rule. c Click Remove. d Click OK.
✑ Alternatively, if Storage DRS rules are preventing Storage DRS from making migration recommendations, you can set the Storage DRS advanced option
IgnoreAffinityRulesForMaintenance to 1.
a In the vSphere Client inventory, right-click the datastore cluster and select Edit Settings. b Select SDRS Automation and click Advanced Options. c Enter 1 in the Value column for IgnoreAffinityRulesForMaintenance. d Click OK.
