of your replacement controller configuration:
1. Determine whether you have an offline or non-DRM-configured subsystem,
and then complete one of the following options:
■ Complete the following substeps if you have an offline or
non-DRM-configured subsystem:
a. Remove a controller from the non-DRM-configured subsystem by
completing the instructions in the “Removing array controllers in
dual-redundant controller configurations” section which starts on
page 121.
b. Complete step 1 through step 4 of the “Installing array controllers in
dual-redundant controller configurations” section (which starts on
page 126) to initialize the replacement controller in the
non-DRM-configured subsystem.
The replacement controller is initialized with no configuration.
c. Remove the replacement controller from the non-DRM-configured
subsystem.
d. Reinsert the controller that was removed in substep a above, and
complete step 5 through step 8 (see page 131) in the “Installing array
controllers in dual-redundant controller configurations” section.
■ Complete the following substeps if you do not have an offline or
non-DRM-configured subsystem:
a. Halt all I/O on the initiator and target sites of the DRM configuration.
b. Disconnect the host port Fibre cables from the controller being
replaced.
c. Remove a controller by completing the instructions in the “Removing
array controllers in dual-redundant controller configurations” section
which starts on page 121.
1. An unknown controller is defined as a controller that is a) not a factory-fresh module,
b) a controller that was in a system that was using a different ACS version than the
system into you are installing the controller or c) a controller with a broken seal with
