Measure Reference Manual

The optical disk system is an enclosure (familiarly called a jukebox) that contains one or more disk
drives and multiple disk cartridges stored in cells. Each cartridge has two sides, and each side is
a volume.
G-series, H-series, and J-series RVUs do not support optical disks. However, Measure and later
PVUs include an OPDISK DDL record for future use. Specifying an OPDISK entity in a RVU that
does not support the entity does not cause an error message but also does not affect the
measurement configuration.
Optical disk records from D-series data can be formatted and displayed.

Entity Specification Syntax for OPDISK Entities
To describe OPDISK entities in D-series RVUs:
OPDISK entity-spec [,entity-spec] ...
OPDISK
collects information about one or more optical disks in the local system.
entity-spec
is specified as:
{ * }
{ $device [ $vol ] [ ( cpu [ , chan [ , ctrl [ , unit] ] ] ) ] }
where:
*
measures all optical disks on the system.
$device
is the device name of the optical disk to be measured. Use an asterisk (*) to indicate all
devices.
$vol
is the name of the optical disk volume to be measured. Use an asterisk (*) to indicate all
volumes.
cpu
is the number of the CPU in which the optical disk is configured. The default is all CPUs.
chan
is the channel number of the optical disk to be measured. The default value is all channels.
ctrl
is the controller number of the optical disk to be measured (0-31). The default is all
controllers.
unit
is the unit number of the optical disk to be measured. The default is all units.
DDL Record for OPDISK Entities (ZMS Style)
The ZMS Style DDL record for OPDISK entities is supported in Measure G11 and later PVUs.
