      Successfully tested iSCSI booting of SNO on OCI using https://github.com/openshift/installer/pull/8886

      Successfully tested iSCSI booting of SNO on OCI using https://github.com/openshift/installer/pull/8886

      Need to add dev-scripts support to test non oci platforms but it could be a stretch goal.

       

      7 Nov 2024: Red

      The PR https://github.com/openshift/installer/pull/8886  to port the OCI-related code from the assisted-service to the installer is still under code review. Testing the code changes on OCI is currently blocked due to uncertainties regarding the testing process on that platform. A meeting is scheduled with Adrien Gentil next week to seek assistance with testing iSCSI boot on OCI.

      For non-OCI iSCSI boot support, development is ongoing within the assisted-service. After discussions with the assisted team, it appears that no major modifications are required in the agent-based installer. However, creating iSCSI boot support in the dev-script environment remains a challenge. Assistance has been requested from agent installer team members to set up the dev-script environment to test iSCSI boot for non-OCI platforms.

      PR to port changes from assisted installer is up for review. Need QE's assistance to test in OCI. As per Manoj, testing the PR in OCI is easier than on baremetal because we do not have the infrastrucure yet to test iSCSI on libvirt for baremetal. Also, dev-script needs to be modified to add iSCSI boot support.

      Epic Goal

      Support booting from iSCSI using ABI starting OCP 4.16.

       

      The following PRs are the gaps between release-4.17 branch and master that are needed to make the integration work on 4.17.

      https://github.com/openshift/assisted-service/pull/6665

      https://github.com/openshift/assisted-service/pull/6603

      https://github.com/openshift/assisted-service/pull/6661

       

      The feature has to be backported to 4.16 as well. TBD - list all the PRs that have to be backported.

       

      Instructions to test the AI feature with local env - https://docs.google.com/document/d/1RnRhJN-fgofnVSBTA6mIKcK2_UW7ihbZDLGAVHSdpzc/edit#heading=h.bf4zg53460gu

      Why is this important?

      • Oracle has a client with disconnected env waiting for it - slack discussion. 

      Acceptance Criteria

      • CI - MUST be running successfully with tests automated
      • Release Technical Enablement - Provide necessary release enablement details and documents.
      • iSCSI boot is enabled on ocp >= 4.16

      Dependencies (internal and external)

      1.  https://issues.redhat.com/browse/MGMT-16167 - AI support boot for iSCSI for COI
      2. https://issues.redhat.com/browse/MGMT-17556 - AI generic support for iSCSI boot
