Removing and replacing Enterprise 3000 disk drives
Overview
This section contains the procedures that are required to upgrade the disk drives in an
Enterprise 3000 computer to CMS R3V9.
These procedures require you to remove the old disk drives in the computer, and replace
them with new disk drives that are preloaded with the CMS R3V9 software. Depending on
the amount of disk space that is required by the customer, you will install from 1 to 10 new
disk drives.

as part of the upgrade procedure. These old disk drives should be saved for
system recovery if any problems occur during the upgrade procedure.
