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 355). Syntax show volume-statistics [volumes] Parameters volumes Optional. A comma-separated list of the names or serial numbers of the volumes for which to show information. For volume syntax, see "Command syntax" (page 20). If this parameter is omitted, information is shown for all volumes. Output Name The name of the volume. Serial Number The serial number of the volume. Bytes per second The data transfer rate calculated over the interval since these statistics were last requested or reset. This value will be zero if it has not been requested or reset since a controller restart. IOPS Input/output operations per second, calculated over the interval since these statistics were last requested or reset. This value will be zero if it has not been requested or reset since a controller restart. Number of Reads The number of read operations since these statistics were last reset or since the controller was restarted. Number of Writes The number of write operations since these statistics were last reset or since the controller was restarted.
