The Exadata compute node, exadbs04, has been having issues for some time. The server had to
be repaired and you just received a new server. Your LVM snapshot was corrupt and now the
compute node must be re-image with an Oracle Support installation image. Which three tasks
would you need to perform to re-image the compute node?
A.
Mount the LVM backup image across the network and recover the system.
B.
Remove exadbs04 from the RAC cluster and all associated Oracle Homes from the central
inventory.
C.
Create a CELLBOOT USB Flash Drive using an external USB drive.
D.
Reboot the new server using a bootable recovery image from the external USB drive.
E.
Reconfigure all site-specific settings (host name, IP addresses, NTP server, and so on).
Explanation:
C: Exadata provides a way for you to create your own CELLBOOT USB. All you
have to is plug-in a USB disk which should be at least 1 GB and run the tool:
$ /opt/oracle.SupportTools/make_cellboot_usb
Exadata turns your USB disk into a bootable disk of active image of your system.
Answer is C,D,E….not B
Hi Matt,
I think the correct answer is BDE, since CELLBOOT USB is used for storage servers.
B: this is a database server, so you need to remove it from cluster inventory
Not C: CELLBOOT USB is used for storage servers not database servers (exadbs04)
D: Reboot using USB containing image

Ans is BDE and for more information on this you can refer book “Oracle Exadata Recipes A Problem-Solution Approach”
Yes, B,D,E
BDE
BCD exceptionally, I do NOT go with Matt and Syed. This is a tricky one. Question is: “to re-image the compute node”.
E is NOT needed for re-image. It is needed to integrate the compute node that you can use him as a replacement for the defect one.
That BCD are necessary you can find in:
Oracle® Exadata Database Machine Maintenance Guide
Re-Imaging Oracle Linux Database Servers
I would go with B,D,E
CELLBOOT USB – as the documentation states and the name suggests is for Storage Servers (CELLS) only.
The machine owner’s guide lists the steps as follows:
Task 1 Contact Oracle Support Services
Task 2 Download Latest Release of Cluster Verification Utility
Task 3 Remove the Failed Database Server from the Cluster
Task 4 Prepare the USB Flash Drive for Imaging
Task 5 Image the Replacement Database Server
Task 6 Configure the Replacement Database Server
