Recovering boot settings after server pattern deployment
If one or more servers do not start after you deployed a new server pattern to those servers, the problem might be that the boot settings were overwritten with the default boot settings that are in the server pattern. For operating systems that are installed in UEFI mode, restoring the default settings might require additional configuration steps to restore the boot configuration.
Procedure
Complete the following manual recovery procedure for each affected server to restore the original boot settings.
For a server with Red Hat Enterprise Linux installed:
If you are accessing the server remotely, establish a remote-control session to the server (see Using remote control to manage Converged, Flex System, NeXtScale, and System x servers).
Restart the server by clicking . When the UEFI splash screen for the server is displayed in the Remote Control session, press F1 to display the Setup Utility.
Select Boot Manager.
Select Add Boot Option.
Select UEFI Full Path Option.
From the list that is displayed, select the entry that includes SAS.
Select EFI.
Select redhat.
Select grub.efi.
Select the Input the Description field.
Type Red Hat Enterprise Linux.
Select Commit Changes.
Make Red Hat Enterprise Linux the first option in the Boot Order, and remove all other options in the Boot Order.
Press Escape, and then select Save changes then exit this menu.
Press Escape, and then select Exit the Configuration Utility and Reboot. The compute node restarts.
For a server with Microsoft Windows Server 2008 installed:
Power on the server, and when prompted, press F1 to enter setup.
Select Boot Manager.
Select Boot from File.
Select the GUID Partition Tables (GPT) System Partition where you installed Microsoft Windows Server 2008.
