.-,-----------.
V |
>--VOLumenames--=----volume_name-+-----------------------------><
Parameters
- DEVclass (Required)
- Specifies the name of the sequential access device class to use.
The device class must be defined in a device configuration file specified by
the DEVCONFIG server option.
If a device configuration file is not available, you can manually create
one. See Administrator's Guide for details.
- VOLumenames (Required)
- Specifies the database backup volume names. If you specify multiple
names, separate them with commas and no intervening spaces.
Examples
Task
Display information about the database backup volumes, BACKUPFILE and
INCREMENTAL.
- Command:
- dsmserv display dbbackupvolume devclass=file
volumenames=backupfile,incremental
- Output:
-
+--------------------------------------------------------------------------------+
| Date/Time: 04/07/1998 13:16:43 |
| Volume Type: BACKUPFULL |
| Backup Series: 7 |
|Backup Operation: 0 |
| Volume Seq: 1 |

where:
- Date/Time
- The date and time that backup data was recorded on the volume.
- Volume Type
- Whether the backup was full or incremental.
- Backup Series
- The identifying number of the backup series. A backup series is a
full backup and all incremental backups before the next full backup.
- Backup Operation
- The operation number of the backup volume. In a backup series the
full backup is operation 0, the first incremental backup is operation 1, the
second incremental backup is operation 2, and so on.
- Volume Seq
- The sequence, or position, of the volume in the backup series.
Volume sequence 1 identifies the first volume of the first operation (a full
backup), and so on. If a full backup occupies three volumes, the volume
sequence numbers are 1, 2, and 3.
- Device Class
- The name of the device class for the volume.
- Volume Name
- The name of the volume.
