PRELIMINARY
Restoring a Storage
Processor Boot Image
This procedure explains how to restore a storage processor s boot image (SP boot image).
When a storage processor (SP) does not start properly and its fault light blinks four times a
second, the cause may be that the SP s boot image has been damaged and is unusable. If
so, a qualified service provider will guide you through the process that this procedure
describes.
CAUTION
Before restoring the boot image, try to correct a startup problem by turning
power to the storage system off, and then on again.
Do not attempt the restoration procedure without the assistance of your
authorized service provider.
