The Oracle Hardware Management Pack packages can be uninstalled using native package tools, such as RPM, or using the wizard-based uninstaller that comes with the Oracle Hardware Management Pack. When the native package method is used to remove packages, if you have previously saved a host credentials cache file using Oracle Hardware Management Pack to facilitate accessing Oracle ILOM using the Host-to-ILOM interconnect, the file will not be deleted. In this case, before uninstalling Oracle Hardware Manaagement Pack packages, run the ilomconfig delete credential command to delete this file.
The wizard-based uninstaller removes the credentials file. Therefore, Oracle recommends that the wizard-based installer be used to uninstall Oracle Hardware Management Pack. For more information, see the Oracle Hardware Management Pack Installation Guide at the link below:
