Displaying IMS Device Statistics (RDEV)

Pend Time

Average time during interval an I/O request waited for an available path to this device (in milliseconds).

Conn Time

Average time during interval in which the path to this device was actually transferring data (in milliseconds).

Disc Time

Average time during interval in which this device was in use but not transferring data (in milliseconds).

Open Dsns

Number of OPEN datasets on this volume.

To limit the below.

scope of the display, add a sub-operand. Examples are shown

Displays all devices beginning with SYS. Displays all devices beginning with 14. Limits scope of the display to the unit named C38.

Limits scope of the display to the volume named SYS001.

DISPLAY R

DEV (SYS*)

DISPLAY R

DEV (14*)

DISPLAY R

DEV (U(C38))

DISPLAY R

DEV (V(SYS001))

If you do not use the U and V sub-operands to specify unit and volume names (as shown in the first two examples), EPILOG determines whether the sub-operand designates a unit or a volser according to the following rules:

A volser is a six-character volume serial ID containing a combination of numerals from 09 or letters from AZ.

A unit is a three-character unit name containing a combination of numerals from 09 or letters from AF.

When a sub-operand is processed, each character is checked. If the length of the sub-operand is greater than three, or a character is greater than F (that is, not a valid hexadecimal number), it is considered a volser.
