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. For volume performance statistics, the system
samples live data every 15 seconds.
Statistics shown only in XML API output are described in
"XML API basetype properties" (page 221)
