This parameter 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.
