iLO drivers


iLO drivers enable to take advantage of features of iLO management engine in HPE ProLiant servers. iLO drivers are targeted for HPE ProLiant Gen8 and Gen9 systems which have iLO 4 management engine. From Pike release iLO drivers start supporting ProLiant Gen10 systems which have iLO 5 management engine. iLO5 conforms to Redfish API and hence hardware type redfish is also an option for this kind of hardware but it will lack the iLO specific features.

For enabling Gen10 systems and getting detailed information on Gen10 feature support in Ironic please check this Gen10 wiki section.

ProLiant hardware is supported by the ilo hardware type and the following classic drivers:

  • iscsi_ilo
  • agent_ilo
  • pxe_ilo

   Note: All HPE ProLiant servers support reference hardware type ipmi. HPE ProLiant Gen10 servers also support hardware type redfish.

The iscsi_ilo and agent_ilo drivers provide security enhanced PXE-less deployment by using iLO virtual media to boot up the bare metal node. These drivers send management info through management channel and separates it from data channel which is used for deployment. iscsi_ilo driver deploys from Ironic conductor node and can do both net-boot and local-boot. agent_ilo driver deploys from bare metal node and always does local-boot (till Liberty release). From Mitaka onwards, agent_ilo supports net-boot and local-boot both.

pxe_ilo driver uses PXE/iSCSI for deployment (just like normal PXE driver), but support automatic setting of requested boot mode from nova. This driver doesn't require iLO Advanced license.
