Measure Reference Manual

H03 PVU this value is stored in this smaller field in order to use the free upper 48 bits for lun and
path. The valid values for target-id are 0 to 999. If target-id is in a descriptor, the wildcard
is all 1s.
SAC-NAME
Logical name associated with the SAC used in this path to the physical volume. Logical names are
maintained by the system configuration database. If the device is a CLIM device, SAC-NAME is
the name of the CLIM(s). The default is all CLIMs. The name is null-filled and null-terminated.
SCSI-ID
SCSI port identifier for this disk.
SERVERNET
(G-series and later RVUs) ServerNet fabric used by this specific path to the disk. 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.
STORAGE-POOL
Name of the Storage Management Foundation (SMF) storage pool to which the measured disk is
assigned (process name of the storage pool process).
Common and ZMS Style Only Counter Field DDL Definitions for DISC Entities
These counter fields are used in both styles of DDL records. Fields that are used in ZMS Style DDL
records only are noted.
Fields are listed alphabetically; subfields are listed in the order they occur in the field.
C
(ZMS Style only) Disk cache metrics. While the C field is included in both the ZMS Style DDL and
the Legacy Style DDL records, the subfield contents and the sequence of the subfields varies based
on the style of the record. For the subfield contents and sequence of the C field for Legacy Style
DDL records, see Legacy Style Only Counter Field DDL Definitions for DISC Entities (page 202). In
the ZMS Style DDL record, this field is divided into these subfields:
Counter TypeDescriptionSubfield
N.A.Number of cache blocks allocated. When TOTALS ONLY
or TOTALS INCLUDE is used, this value is the maximum
BLKS
number of cache blocks allocated. BLKS is not a counter
but a value obtained from an internal disk process data
structure.
N.A.(ZMS Style only) Cache block size, in bytes.BLOCK-SIZE
Snapshot(ZMS Style only) Number of cache blocks that were in use
at the beginning of the measurement. This value is part of
BLOCKS-INUSE-START
the structured DISC record but does not appear in Legacy
Style DISC reports. When TOTALS ONLY or TOTALS
INCLUDE is used, this value is the total number of cache
blocks in use at the beginning of the measurement.
