data transfers are displayed.
–nodes <node_list>
Specifies that the display is limited to specified nodes and Physical Disks (PDs) connected to those
nodes. The node list is specified as a series of integers separated by commas (1,2,3). The list
can also consist of a single integer (1). If the node list is not specified, all disks on all nodes are
displayed.
–slots <slot_list>
Specifies that the display is limited to specified PCI slots and PDs connected to those PCI slots. The
slot list is specified as a series of integers separated by commas (1,2,3). The list can also consist

–ports <port_list>

–metric both|time|size
Selects which metric to display. Metrics can be one of the following:
• both - (Default) Displays both I/O time and I/O size histograms.
• time - Displays only the I/O time histogram.
• size - Displays only the I/O size histogram.
–timecols <fcol> <lcol>
For the I/O time histogram, show the columns from the first column <fcol> through last column
<lcol>. The available columns range from 0 through 31.
• The first column (<fcol>) must be a value greater than or equal to 0, but less than the value
of the last column (<lcol>) (default value of 6).
• The last column (<lcol>) must be less than or equal to 31 (default value of 15).
