Measure Reference Manual

Devices connected by an FCSA or CLIM are dual fabric adapters, that is, they are connected
to both the X and Y fabrics. For these devices, only "*" or "X" should be specified in the
LIST command, and only "X" should be specified in the LISTACTIVE command.
group
(G-series and later RVUs) is the group number of the device to measure. (The group
corresponds to the physical enclosure.)
module
(G-series and later RVUs) is the module number of the device to be measured.
slot
(G-series and later RVUs) is the slot number of the device to be measured.
scsi-id
(G-series and later RVUs) is the SCSI port identifier of the device to be measured. Measure
supports a range of 0 to 65534.
sac
is the name of the CLIM. Only one CLIM name is supported for the DEVICE entity.
lun
is the logical unit number assigned to a disk within a CLIM.
NOTE: For a LISTACTIVE command, you must name specific devices to be measured; a wildcard
(*) cannot be used.
Examples
FCSA device: + LISTACTIVE DEVICE $TAPE1 (0,X,110,3,1)
+ LISTACTIVE DEVICE $TAPE2 (0,X,110,3,1,101)
CLIM device: + LISTACTIVE DEVICE $TAPE3 (0,X,C1002531,201)
DISC
LISTACTIVE [ DISC ] [ disc-spec [ , listactive-spec ]
disc-spec
identifies the disk to measure, specified as:
{ $discname ( cpu , svnet , group , module , slot [, scsi-id ] )}
or for disks with multiple paths only, specified as:
{ discname-path ( cpu ) }
or for CLIM-attached devices only, specified as:
{ discname ( cpu , svnet , sac , lun [, partition ] ) }
discname
is the name of the disk to be measured.
cpu
is the number of the CPU in which the disk is configured.
svnet
(G-series and later RVUs) is the ServerNet fabric used by this specific path to the device.
The Measure subsystem measures all disk records relative to the specified fabric. The value
is 0 for X fabric, 1 for Y fabric. The default is to measure records for both fabrics.
Disks connected by a ServerNet/DA do not have an X or Y fabric. To indicate these disks,
use an asterisk (*). In this case, you can use an asterisk (*) in the LISTACTIVE command
as long as the rest of the entity specification describes one disk.
Disks connected by an FCSA or CLIM are dual fabric adapters, that is, they are connected
to both the X and Y fabrics. For these disks, only "*" or "X" should be specified in the LIST
command, and only "X" should be specified in the LISTACTIVE command.
