Upgrading to a dual-redundant controller configuration
Use the following steps to upgrade a single-controller configuration subsystem to
a dual-redundant configuration subsystem. To replace failed components, see the
“Replacing BA370, M2100 & M2200 Enclosure Elements” chapter that starts on
page 101 for more information. Before beginning this procedure, obtain the
following items:
■ A second controller with the same software version and patch level as
installed in the current single-controller
■ A second cache module with the same memory configuration as installed in
the current cache module
■ A second ECB
■ For BA370 enclosures only, a second ECB Y-cable
Use the following steps to install a second controller, cache module and ECB:
Caution: For BA370 enclosures only:
■ After installing the controller, check the PVA SCSI ID number on the master
enclosure to ensure that it represents the correct enclosure number (ID 0).
■ If the SCSI ID number is not 0, reset it to ID 0 before starting the controller.
