When you restore a deleted host to the system configuration information, the host still remains in the deletion history in the Deletion History of System Configuration Information dialog box. If there is a large volume of deletion history, a space shortage may occur in the database. For this reason, you should periodically delete unneeded deletion history information.

To delete deletion history, open the Deletion History of System Configuration Information dialog box. In this dialog box, select the hosts whose history is no longer needed, and then click the Delete button. If you click the Delete All button, all deletion history is deleted.

If you delete a host from the System Configuration window manually and have selected the setting for not deleting the inventory information, the host is deleted from the system configuration information but its inventory information remains. In such a case, deleting the deletion history will not delete the inventory information.
