Oversubscription Situation

This attribute reports an oversubscription situation, that is when:

1.The storage pool is configured for thin provisioning (“thin storage pool”)

2.the SubscribedCapacityPercentage parameter is greater than 100%, and

3.the ConsumedCapacityPercentage parameter is greater than 75%

Such situation is highly critical because the inability to allocate additional space to a volume when requested by the subscriber host will lead to catastrophic data loss and corruption.
