Is there a way to see processors being used by lpars when they are set to Uncapped on a 570.
Thanks

"lparstat -i" should provide whatever info you want about the running partition.

The command vmstat on a shared-processor LPAR (SPLPAR) also shows columns: pc and ec.

pc = amount of CPUs the LPAR has consumed in the interval
ec = percentage of the LPAR's CPU entitlement consumed

On a capped LPAR, ec cannot go beyond 100, on an uncapped LPAR, you can see ec go over 100% and a pc column higher than the defined entitlement.

The amount an uncapped LPAR can consume is limited by the number of CPUs in the pool (plus the CPUs that other idle LPARs have temporarily relinquished to the pool) and by the number of virtual CPUs you have active in the LPAR. For instance an LPAR that has an entitlement of 1.5 CPUs and 3 virtual CPUs and is uncapped, can consume op to 3 CPUs if there are enough CPUs in the pool when it wants to use 'em. So you might see an ec column of 200 and a pc column of 3.0 if that LPAR is busy enough and the CPUs are free for that LPAR to use.
