to learn more about the internal CeLLBoot uSB drive, please see recipe 8-1.
The first step to take is to understand the scope of your failure. In other words, confirm whether you have
hardware failure and if so, whether you have a multiple disk failure impacting both disks that comprise your system
area. If your outage is deemed unrecoverable using single disk drive replacement, it's time to initiate the storage cell
rescue procedure.

If you have only lost a single disk containing your system volumes, use the recovery steps provided in
recipe 8-8. We don't advise performing a storage cell rescue from the CeLLBoot uSB drive unless you need to or wish
to test the procedure in non-production environment.
If your outage is deemed unrecoverable using single disk drive replacement, it's time to initiate the storage cell
rescue procedure.
1.
Before starting the rescue, we recommend contracting Oracle Support to open a Service
Request.
2.
To start the procedure, log in to your ILOM web console and reboot your storage cell.

We recommend using the ILoM console as opposed to the kvM console during this process. When logged in to
the kvM console, you may experience “green-out” periods in which you lose visibility to the console. Since some of the
steps in the storage cell recovery process require you to press keys within a fixed time interval, you may lose the ability
to act promptly and this can delay your rescue process.
3.
As soon as you see the Oracle Exadata splash screen, press any key on the keyboard. You
will need to do this quickly as the screen only displays for five seconds. Figure
8-3
shows
what this splash screen looks like.
