Deleting Volume History

To delete sequential volume history information collected by the server when the information is no longer needed, first complete the following fields and then click Finish, or click Cancel to end the task. For example, you may want to delete information about volumes used for obsolete database backups.

Note:

For users of DRM, the database backup expiration should be controlled with the SET DRMDBBACKUPEXPIREDAYS command instead of this DELETE VOLHISTORY command.  Using the DELETE VOLHISTORY command removes TSM's record of the volume. This can cause volumes to be lost that were managed by the MOVE DRMEDIA command.  The recommended way to manage the automatic expiration of DRM database backup volumes is by using the SET DRMDBBACKUPEXPIREDAYS command.

Entries Prior To Date

Enter the date to use to select sequential volume history information to be deleted. Tivoli Storage Manager deletes only those records with a date on or before the date you specify.

The settings for Entries Prior To Date are:

MM/DD/ YYYY Specifies that you want to delete records created on or before a specific date in MM/DD/YYYY format.

Example: 01/31/1997

TODAY Specifies that you want to delete records created on or before the current date.
TODAY -numdays or -numdays Specifies that you want to delete records created on or before the current date minus a specific number of days. The maximum value for the number of days is 9999.

Example: To delete records that are 30 or more days old, you can specify Entries Prior to Date=Today-30 or Entries Prior to Date=-30.

Entries Prior To Time

Enter the time to use to select records to delete from the volume history file. This parameter is optional. Of the records that match the date criteria you specify with Entries Prior to Date, Tivoli Storage Manager deletes only those records with a time that is the same as or earlier than the time you specify with Entries Prior to Time.

The settings for Entries Prior To Time are:

HH:MM:SS Specifies that you want to delete records created on or before a specific time on the specified date in HH:MM:SS format.

Example: 12:30:22

The default value is midnight (00:00:00) on the specified date

NOW Specifies that you want to delete records created on or before the current time on the specified date.

Example: If you delete volume history at 9:00 with Entries Prior to Time=Now, Tivoli Storage Manager deletes records with a time of 9:00 or earlier on the specified date.

NOW +numhours: numminutes or +numhours: numminutes Specifies that you want to delete records created on or before the current time plus a specific number of hours (and optionally, minutes) on the specified date.

Example: If you delete volume history at 9:00 with Entries Prior to Time=Now+3 or Entries Prior to Time=+3, Tivoli Storage Manager deletes records with a time of 12:00 or earlier on the specified date.

NOW -numhours: numminutes or -numhours: numminutes Specifies that you want to delete records created on or before the current time minus a specific number of hours (and optionally, minutes) on the specified date.

Example: If you delete volume history at 9:00 with Entries Prior to Time=Now-3:30 or Entries Prior to Time=-3:30, Tivoli Storage Manager deletes records with a time of 5:30 or earlier on the specified date.
