Use this command to display sequential volume history information. To save sequential volume history information to one or more files, use the BACKUP VOLHISTORY command.
Use the VOLUMEHISTORY server option to specify one or more volume history files. After the server is restarted, Tivoli® Storage Manager updates volume information in both the database and the files.
Use the QUERY BACKUPSET command to query specified backup set information.
Privilege class
Any administrator can issue this command.

BOTM (Beginning Of This Month) The first day of the current month. BOTM BOTM+days The first day of the current month, plus days specified. BOTM+9 To include files that were active on the 10th day of the current month.
- ENDDate
- Specifies that you want to display information ending with records
created on the specified date. This parameter is optional. The default
is the current date. You can specify the date using one of the values below:

Field descriptions
- Date/Time
- The date and time that the volume was created.
- Volume Type
- The type
of volume:
- BACKUPFULL
- Full database backup volume.
- BACKUPINCR
- Incremental database backup volume.
- BACKUPSET
- Client backup set volume.
- DBSNAPSHOT
- Snapshot database backup volume.
- EXPORT
- Export volume.
- REMOTE
- A volume used on the library client, which is the Tivoli Storage Manager server named in the Volume Location field. See the volume history on the server that is the library client to get details about how the volume is used.
- RPFILE
- Recovery plan file object volume created assuming full and incremental database backups.
- RPFSnapshot
- Recovery plan file object volume created assuming snapshot database backups.
- STGDELETE
- Deleted sequential access storage pool volume.
- STGNEW
- Added sequential access storage pool volume.
- STGREUSE
- Reused sequential access storage pool volume.
- Backup Series
- The value of this field depends on the volume type:
- For BACKUPFULL or BACKUPINCR volume types: the backup series identifier.
- For the DBSNAPSHOT volume type: the identifier of the backup series that is associated with the DBSNAPSHOT entry.
- For the RPFILE volume type: the identifier of the backup series that is associated with the RPFILE entry.
- For the RPFSNAPSHOT volume type: the identifier of the backup series that is associated with the RPFSNAPSHOT entry.
- For BACKUPSET volume types: this field is blank.
- For all other volume types: always 0.
- Backup Operation
-
For BACKUPFULL or BACKUPINCR volume types: the operation number of this backup volume within the backup series. The full backup within a backup series is operation 0. The first incremental backup for that full backup is operation 1, the second incremental backup is operation 2, and so on.
For DBSNAPSHOT volume types: the operation number of this DBSNAPSHOT volume within the DBSNAPSHOT series.
For all other volume types: always 0.
This field is blank when the volume type is BACKUPSET.
- Volume Seq
- The sequence or position of the volume within the backup series.
- For BACKUPFULL or BACKUPINCR volume types: the sequence, or position, of the volume within the backup series. Volume sequence 1 identifies the first volume used for the first operation (a full backup), and so on. For example, if the full backup occupies three volumes, these volumes are identified as volume sequence 1, 2, and 3, respectively. The first volume of the next operation (the first incremental backup) is then volume sequence 4.
- For BACKUPSET volume types: the sequence, or position, of the volume within the BACKUPSET series.
- For DBSNAPSHOT volume types: the sequence, or position, of the volume within the DBSNAPSHOT series. Volume sequence 1 identifies the first volume used for the first DBSNAPSHOT operation, and so on.
- For EXPORT volume types: the sequence number of the volume when it was used for exporting data.
- For RPFILE volume types: the value of this field is always one (1).
- For all other volume types: always 0.
- Device Class
- The name of the device class associated with this volume.
- Volume Name
- The name of the volume.
- Volume Location
- The location of the volume. This information is available only
for the following volume types:
- BACKUPFULL
- BACKUPINCR
- EXPORT
- REMOTE
- RPFILE
For the volume type of REMOTE, this location field is the server name of the library client that owns this volume.
For the volume type of RPFILE, this location field is the server name defined in the device class definition used by the PREPARE command when the DEVCLASS parameter is specified.
- Command
- When the volume type is EXPORT or BACKUPSET and the volume sequence
is 1 (for example, the first volume), this field shows the command
that was used to generate the volume. If the EXPORT or BACKUPSET is
on more than one volume, the command is displayed with the first volume
but not with any of the other volumes.
For any volume type other than EXPORT or BACKUPSET, this field is blank.
Note: The
following fields are not used by Tivoli Storage
Manager servers
that are V6.3 or later. However, the fields are displayed for compatibility
with earlier releases.
- Database Backup ID High
- Database Backup ID Low
- Database Backup Home Position
- Database Backup HLA
- Database Backup LLA
- Database Backup Total Data Bytes (MB)
- Database Backup Total Log Bytes (MB)
- Database Backup Block Num High
- Database Backup Block Num Low
