You specify LIST TAPETABLEOFCONTENTS(volser) to get a list of the information contained in the TTOC for a tape backup or migration level 2 volume managed by DFSMShsm. Preceding the list is an echo of the LIST command issued.
Table 1 explains the output labels when you request information from the TTOC.
Printer Output Label (OUTDATASET or SYSOUT) | Terminal Label | Description |
---|---|---|
VOLSER | VOLSER | This field contains the volume serial number of the tape volume. |
UNIT |
UNIT NAME | This field contains the name of the unit where this volume can be allocated. |
VOL |
VOL TYPE | This field contains the DFSMShsm volume category of the tape volume. SPILL indicates a spill backup volume. D(nn) indicates a backup volume assigned to day nn in the backup cycle. UNASS indicates that the volume has not been assigned as a daily or spill backup volume, or that it has been assigned as a daily backup volume but not to a specific day in the backup cycle. ML2 indicates that the volume is a tape migration level 2 volume. |
REUSE |
CAPACITY | This field contains the nominal number of blocks that DFSMShsm
could write to this tape if it were emptied and written again. It
is the actual average in this HSMplex for all full tapes of its cartridge
type, recording technology, and function as calculated by the reporting
host when it last started DFSMShsm. The blocks are 16 384 bytes
each. ****** indicates that no ML2 or backup tape volumes marked full exist. |
VALID |
VALID BLOCKS | This field contains the number of blocks of data on the tape volume that are still valid. |
PCT |
PCT VALID | This field contains the percent that this tape's valid blocks
are of the reuse capacity. A value of 100 is shown for tapes whose number of valid blocks exceed the reuse capacity. |
VOL |
VOL STATUS | Empty under this heading indicates that the tape is empty.
Full under this heading indicates that while DFSMShsm was writing to tape, either an end-of-tape marker was reached or a data-movement error occurred, and the volume was marked full to prevent further use. Partial under this heading indicates that the tape is neither empty nor full. The tape has been written to but may or may not contain valid data. |
RACF | RACF | YES or Y indicates that the tape volume is RACF® protected. |
PREV |
PREV VOL | If this field contains a volume serial number, the first data set on this tape volume is valid and does not begin on this volume, but is a continuation of the last data set on the indicated previous volume. If the field contains NONE, either the first data set is not valid or it begins on this volume. |
SUCC |
SUCC VOL | If this field contains a volume serial number, the last data set on this tape volume is valid and does not end on this volume. The data set is continued on the indicated succeeding volume as the first data set on that volume. If the field contains NONE, either the last data set is not valid or it ends on this volume. |
NUM |
NUM REC | This field contains the number of offline control data set T records, including the base and extension records, used to contain this TTOC. |
ONE |
ONE FILE | A YES or Y indicates that the tape volume has a single file containing the user data sets. A NO or N indicates that each user data set on the tape volume is in a separate tape data set. An *** indicates the ONE FILE is irrelevant because DFSMShsm has not written on the volume. |
ALT |
ALTVOL | Volume serial number of duplicate tape copy created by DFSMShsm TAPECOPY command; *NONE* if duplicate tape is not so created; ****** indicating that the information is not known. If the optional parameter SELECT (DISASTERALTERNATEVOLUMES) is specified, this field shows the alternate tape volume that has been flagged as disaster alternate volume. |
LIB | LIB | This field contains the tape library information for the volume.
The field can be:
|
STORAGE |
STORAGE GROUP | This field contains the name of the storage group. If there
is a library name for the volume, there must be a storage group name.
Connected tape volumes must be in the same storage group and library.
The storage group field can be:
|
DATA SET NAME | DATA SET NAME | This field contains the name of the data sets on the volume. If the data set is on a tape backup volume, this name is the DFSMShsm-generated backup version name. If a data set is on a tape migration level 2 volume, this name is the original data set name, not the migrated data set name that DFSMShsm generates. |
NUM BLOCKS | NUM BLOCKS | This field contains the number of blocks used on this volume for this data set. |
RELATIVE FBID | REL FBID | This field contains the file sequence number of this data set or the set of blocks relative to the beginning of the single tape volume. For example, the first data set or data set segment on the tape volume has a relative FBID of 4 independent of any predecessor tapes. |
VSAM | VSAM | YES or Y indicates that the data set is a backup version or a migration copy of a VSAM data set. |
RACF | RACF | YES or Y indicates that the data set is discretely RACF-protected. |
LAST REF DATE | LAST REF DATE | This field contains the last date when the migrated data set was referred to. This field does not apply to backup versions. |
EXP DATE | EXP DATE | This field contains the expiration date of the user’s data set. This field does not apply to backup versions. For ML2 tapes, asterisks means the date is a never expire date. |
A field containing only **** is not applicable to this volume (see individual field descriptions in the sample lists.) |
