Global Cache or Array Cache Details and Usage

Hello. Is there a SE command to get the details and usage of the PowerMAX8000 Global Cache,  how much is available and how much is in use. Or, details on cache slots etc. Or, there any way to check that in UNIVMAX.  We need to determine if our array is under cached and does it need a cache upgrade. Some commands to see MIN_PERF_CACHE and current cache. And, we also need to determine, if we are hitting the write-pending limits.  Thank You.
