Discovery ISO not booting

❗ Red Hat does not provide commercial support for the content of this repo. Any assistance is purely on a best-effort basis, as resource permits.

Sometimes the discovery iso will not boot here are a few things to check.

Dell

Plugin type

For some versions of iDRAC the plug-in type can stop the boot iso from working. If you are trying to install Redhat Openshift Container Platform (RHCOP) version >=4.7 then follow the instructions bellow from the ipi docs

There is a known issue with version 04.40.00.00. With iDRAC 9 firmware version 04.40.00.00, the Virtual Console plug-in defaults to eHTML5, which causes problems with the InsertVirtualMedia workflow. Set the plug-in to HTML5 to avoid this issue. The menu path is: Configuration → Virtual console → Plug-in Type → HTML5 .

Note if you are trying to install RHOCP version 4.6 then the plugin-in should be set to eHTML5.

Clear UEFI Boot entries

For RHOCP version 4.8 sometimes wont boot despite the plug-in type correct. Try the following:

  1. (Re)Boot machine
  2. Hit F11 to enter Boot Manager
  3. Select "One-shot UEFI Boot Menu"
  4. Scroll to the bottom and select "Delete Boot Option"
  5. Select all options
  6. Click "Commit Changes and Exit"
  7. Click "Finish"
  8. Click "Finish" & Confirm exit
