Requesting data set information from the MCDS

Table 1 explains the output labels for a list of all data sets, all data sets that have the same first qualifier, or a specific data set.

Table 1. Output labels when you request MCDS information for data sets
Printer Output Label (OUTDATASET or SYSOUT) Terminal Label Description
DATASET NAME DSN This field contains the name of the user data set.

Start of changeMIG
VOLUMEEnd of change

 MIGVOL This field contains the volume serial number of the migration volume the data set is on if the data set is currently migrated. If the data set is on more than one tape migration level 2 volume, this field contains the volume serial number of the first volume the data set is on. The field contains ONLINE if the data set has been recalled.

LAST REF
DATE

 LAST REF This field contains the date of the most recent reference of the data set.

MIGRATED
DATE

 MIG This field contains the date when the data set was last migrated.

TRKS
ALLOC

 TRKS If the data set is currently migrated, this field contains the number of tracks allocated for the data set on the primary volume from which the data set migrated. If the data set is recalled, this field is the number of tracks allocated for the recalled data set.

QTY
2K BLKS

 2K BLKS This field contains the size, in 2 KB blocks, of the data set on the migration volume. This field does not apply to tape.

TIMES
MIG

 TIMES MIG This field contains the number of times DFSMShsm has migrated the data set. If migration cleanup has deleted the data set record, this is the number of times DFSMShsm has migrated the data set since the record was deleted.

DS
ORG

 DSO This field contains the type of data set organization: PE (partitioned data set extended) PS (physical sequential), PO (partitioned), DA (BDAM), VS (VSAM), PSL (large format sequential) or *** if the data set organization is unknown.

SDSP
DS

 SDSP A YES under this heading indicates that the data set resides in a small-data-set-packing data set.

QTY
16K BLOCKS

 16K BLOCKS This field contains the size, in 16 KB blocks, of the data set on the tape migration level 2 volume. If the data set is recalled, but might be eligible for reconnection during a subsequent migration, this value contains the size, in 16 KB blocks, that the data set would be on the tape migration level 2 volume. This field does not apply to DASD migration volumes.

LAST MIG
VOLUME

 LAST MIGVOL This field contains the volume serial number of the last tape migration level 2 volume if the data set spans more than one tape volume. *NONE* indicates that the data set does not span more than one tape volume. This field does not apply to DASD.
A field containing only **** is not applicable (see individual field descriptions in the sample lists.)

Figure 1 is a sample of a printer list from the MCDS for all data sets. If you request information for a specific data set, the list contains only the entry for that data set.

To get a list of the VSAM data sets from the MCDS, specify the LIST command with the DATASETNAME SELECT(VSAM) parameters. The list of VSAM data sets contains the same header information and a list of object names by which you can automatically recall the data set.

Figure 2 is a sample printer list from the MCDS for VSAM data sets when you specify the DATASETNAME SELECT(VSAM) and MIGRATIONCONTROLDATASET parameters.
