Measure Reference Manual

For devices connected by an FCSA or CLIM, use 0 to indicate the X fabric. By convention, dual
fabric controllers are specified by X.
GMS
is the physical location address (group, module, slot). The GMS structure consists of these fields:
group
INT(32):value:1
is the group number of the device to be measured. (The group corresponds to the physical
enclosure.) Use the literal -1 to indicate all groups.
module
INT(32):value:1
is the module number of the device to be measured. Use the literal -1 to indicate all modules.
slot
INT(32):value:1
is the slot number of the device to be measured. Use the literal -1 to indicate all slots.
device^name
INT:value:12
is the name of the device to be measured. The name must be left-justified and blank-filled and
must start with a dollar sign ($). Use a dollar sign and an asterisk ($*) to indicate all devices.
PLPT
(Measure H03/J01 and later PVUs) is a structure that contains information about the device
to be measured.
Struct plpt^def (*)
Begin
unsigned(8) plpt^flags; ! Flags for interpreting this struct
unsigned(8) path; ! Path
Int lun; ! Logical unit number
Int partition; ! Partition number (0, if not partitioned)
Int target^id; ! 0, for CLIM; scsi-id for non-CLIM
End;
plpt^flags
UNSIGNED(8):value:1
is an array of bit flags that describe how this structure should be interpreted.
Bit 0 (%H80) MEAS_CLIM_REL: This bit is always 1 in Measure H03 and later PVU data
files.
Bit 1 (%H40) MEAS_PATH_SEL: This bit is only used in the entity descriptor when selecting
a DISC with multiple paths for measurement. When it is 1, it specifies device selection by
device^name and path only, and not by GMS, lun, partition,target^id or
config^name.
Bit 2 (%H20) MEAS_CLIM_DEVICE: Indicates that this descriptor is for a CLIM device.
Bit 3 (%H10) MEAS_MULTIPLE_CLIMS: (H06.23/J06.12 and later RVUs) Indicates that the
config^name field in this descriptor contains more than one CLIM name. Valid only with
DISC entity and can only be used for descriptors for MEASREAD, MEASREAD_DIFF_, and
MEASWRITE_DIFF_ procedure calls.
path
UNSIGNED(8):value:1
is the path of the device to be measured. Use the literal -1 to indicate all paths. The following
literals can also be used: MEAS_PATH_PRIMARY, MEAS_PATH_BACKUP,
MEAS_PATH_MIRROR, and MEAS_PATH_MIRROR_BACKUP. Valid only with DISC entity.
