Release Extreme Cache
Overview
This function releases the Extreme Cache for each CE.
After the Extreme Cache is released, PFM cannot be used as an Extreme Cache.
This function is supported in the ETERNUS DX500 S5/DX600 S5/DX900 S5 and the ETERNUS DX8900 S4.
If the use of Extreme Cache is to be stopped in a CE, use this function to release the Extreme Cache. PFMs cannot be removed if Extreme Cache is not released.
