Additional New Primitives Support on ESXi 5.x
HP 3PAR OS 3.1.1 or later supports additional new primitives, called TP LUN Reporting, where
the ESXi 5.x is notified that a given LUN is a thin provisioning LUN by enabling the TPE bits of the
READ Capacity (16) and enables the host to use features such as sending the UNMAP command
to these LUNs. The TPE bit is enabled for TPVVs and R/W snapshot of TPVV base.
The Quota Exceeded Behavior present in ESXi 5.x is accomplished through the "Thin Provisioning
Soft Threshold Reached" check condition, providing alerts and warnings.
