SA model controllers.

This command reports the controller host bus type, bus speed, and bus width.

Example for 9690SA:

//localhost> /c2 show ctlbus

/c2 Controller Bus Type = PCIe

/c2 Controller Bus Width = 8 lanes

/c2 Controller Bus Speed = 2.5 Gbps/lane

/cx show driver

This command reports the device driver version associated with controller
/cx.

Example:

//localhost> /c0 show driver

/cx show dpmstat [type=inst|ra|ext]

This feature only applies to 9750 model controllers and 9000 series SX/SE/
SA model controllers. The type=ext feature is only for SE/SA controllers.

This command shows the configuration and setting of the Drive Performance
Monitor, and a summary of statistics for drives attached to the controller.

The optional type attribute specifies which statistics will be displayed. The
available options are: inst for Instantaneous, ra for Running Average, and ext
for Extended Drive Statistics. If you do not specify a type, the display will
show the default set of drive statistics, which is the type inst.

inst (Instantaneous). This measurement provides a short duration average.

ra (Running Average). Running average is a measure of long-term averages
that smooth out the data, and results in older results fading from the average
over time.

ext (Extended Drive Statistics). The extended drive statistics refers to
statistics of a drive's read commands, write commands, write commands with
FUA (Force Unit Access), flush commands, and a drive sectors's read, write,
and write commands with FUA.

Additional statistics are available for drives at specific ports. For details, see
“/cx/px show dpmstat type=inst|ra|lct|histdata|ext” on page 110.

Drive Performance Monitoring can be turned on and off using the command
“/cx set dpmstat=on|off” on page 68.
