Symptoms

OS Bootup on Exadata hangs after GRUB screen, but GUI hostconsole does not show error or accept keyboard entry.

This hang occurs on bootup between grub image selection and OS available for login.

Changes

The system shutdown either on command or node crash and reboot.

Cause

The GUI / JAVA console lags behind (~5-15 lines) behind the text terminal during this time. Once the OS is available for login, either console is correct and showing the same information.

Unfortunately this causes the GUI console to not display the failing issue or allow you to input prompted info.

In this example the boot was stopping on fsck and required the user to login as root - which was not seen in the GUI console:

EXT4-fs (dm-0): 31 orphan inodes deleted
EXT4-fs (dm-0): recovery complete
EXT4-fs (dm-0): mounted file system with ordered data mode. Opts (null)
dracut: Mounted root filesystem /dev/mapper/VGExaDb-LVDbSys1
dracut: Loading SELinux policy
dracut: SELinux: Could not open policy file <= /etc/selinux/targeted/policy.26: No such file or directory
dracut: Switching root

From SSH Text Console the user was able to see the prompt for login:

EXT4-fs (dm-0): mounted filesystem with ordered data mode. Opts: (null)

dracut: Mounted root filesystem /dev/mapper/VGExaDb-LVDbSys1

dracut: Loading SELinux policy

dracut: SELinux: Could not open policy file <= /etc/selinux/targeted/policy/policy.26: No such file or directory

dracut: Switching root

Solution

Start the console from an SSH terminal - for example: ssh root@ExaMyDB01-ILOM

-> start /SP/console
Are you sure you want to start /SP/console (y/n)? y

This will allow you to see the actual message causing issues and login as needed.
