Solution 2142573.1 : Rebooting a BDA Server Leads to a Black Screen with Blinking Cursor Instead of the Grub Menu

Applies to:

Big Data Appliance X5-2 Hardware - Version All Versions and later
Linux x86-64

Symptoms

Rebooting a BDA server gets to the point where the grub menu should show up but instead of that a black screen with blinking cursor is visible.

It looks like the USB drive is corrupted

Cause

The cause is unknown but if the USB is broken/corrupt, booting from it may be cause a hang. Booting from the hard disk first may workaround the issue.

Solution

If the USB is corrupted try changing the boot order in the BIOS to boot from the hard disk first.

(You might also try to boot into a Linux ISO, mount (root) i.e. /dev/md2, and run /opt/oracle/bda/bin/bdacheckhw to overview any hardware issues.)

1. Verify the boot order.

a) Run 'ubiosconfig export all -x /<path>/bios.xml'.

For example:

# ubiosconfig export all -x /tmp/bios.xml

Output looks like:

# ubiosconfig export all -x /tmp/bios.xml

Wrote backup of BIOS configuration to '/tmp/bios.xml'.

b) From /tmp/bios.xml the boot_order should show output like:

<boot_order>
<boot_device>
<description>USB:USBIN:ORACLE UNIGEN-UFD PMAP</description>
<instance>1</instance>
</boot_device>
<boot_device>
<description>RAID:PCIE6:(Bus 50 Dev 00)PCI RAID Adapter</description>
<instance>1</instance>
</boot_device>
<boot_device>
<description>PXE:NET0:IBA XE Slot 4000 v2196</description>
<instance>1</instance>
</boot_device>
...
</boot_order>

Where the boot order is:

>USB:USBIN:ORACLE UNIGEN-UFD PMAP<
>RAID:PCIE6:(Bus 50 Dev 00)PCI RAID Adapter<
>PXE:NET0:IBA XE Slot 4000 v2196<

2. Try to boot into the hard disk first.
Normally we boot into the USB first (as above), but in the case of a corrupt USB you can try to boot into the hard disk first.

In the ILOM console when booting, use Ctrl-E to get to the BIOS screen and go to: Boot > Boot Device Priority and move "RAID:PCIE6:(Bus 50 Dev 00)PCI RAID Adapter" to the top of the list.
