Upgrading to a Dual-Redundant Controller Configuration
Use the following steps to upgrade a single-configuration subsystem to
a dual-redundant configuration subsystem. To replace failed
components, see Chapter 5, “Replacement Procedures,” for more
information. Before you complete this procedure, you’ll need the
following items:
n Controller with the same software version and patch level that’s
installed on the subsystem’s current single controller
n Cache module with the same memory configuration that’s installed
in the current cache module
n ECB storage building block (SBB) for a dual-redundant
configuration
n ECB cable
