Controller Replacement in a DRM Configuration
When a failed controller running ACS V8.7P needs to be replaced, follow the supported
procedures in the HP StorageWorks HSG60 and HSG80 Controller and HSx80 Cache Module
Replacement Procedures for Array Controller Software V8.7x-x Release Notes. This
document can be obtained at:
http://h18006.www1.hp.com/products/sanworks/drm/relatedinfo.html
It is important to note that these procedures specify a new controller from the factory or a
newly initialized (purged of an old configuration) controller. Using a factory-fresh or newly
initialized (configuration-free) controller is particularly important when your configuration is
set up for DRM. Failure to use a newly initialized controller causes cache corruption on the
replacement controller mirrored cache.
