show volume-statistics
Description Shows live performance statistics for all or specified volumes. For each volume these statistics
quantify I/O operations between hosts and the volume. For example, each time a host writes to a
volume’s cache, the volume’s statistics are adjusted.
Statistics shown only in XML API output are described in "XML API basetype properties" (page 367).
