Storage resource by pool metrics
Unisphere collects and displays metrics for storage resource (by pool).
Within the PM metrics section, V4 is used to denote that the metric is supported only by a storage system (array) running PowerMaxOS 10 (6079). V3 is used to denote that the metric is supported only by a storage system (array) running HYPERMAX OS 5977 or PowerMaxOS 5978. Metrics without the denotation are supported by all storage systems (arrays).
The following table lists all metrics that are available for storage resource group (by pool).
