Media Actions

Media actions provides an overview of all media actions, such as introduction in the SEP sesam environment, initialization, readability check, purge, etc., within the specified time frame. By default, all media actions of the last backup day are displayed. By using Filter, you can filter the overview by date range and/or media action status. Filter settings remain in effect even if you switch to another tab and are dismissed when the Media actions tab is closed.

As of v. 4.4.3 Grolar you can use a force refresh by clicking Shift and Refresh button to clear the GUI cache memory. In some cases clicking only the Refresh button won't show the updated view.

The following media actions might be displayed:

  • introduce (intro): A new medium is registered in the SEP sesam environment.
  • initialize (init): A process that validates if a medium is available for backup. If a medium meets the requirements (e.g., its EOL has expired and it is not write-protected – locked), it can then be initialized, deleting all data contained on it and preparing it for use again.
  • EOM (end of media): EOM specifies whether there is still free space left on the medium or tape. If there is no free space left, the medium or tape is full and can no longer be used for storing data.
  • inventory: A process that scans media in the device and updates SEP sesam information about the media in the tape library.
  • read check: A process that verifies the readability of the backup on tape media.
  • purge: A data store related process. When the upper value for the used disk space on the data store – HWM is reached, a data store purge process is started for all EOL-free save sets. The oldest free save sets are deleted first. Purging is done until the LWM (low watermark) is reached.
