Replacing HS x 80 Cache Modules in Single and
Dual-Redundant Controller Configurations
Replacing a cache module involves transferring the cache memory DIMMs from
the failed cache module to the replacement cache module. Use the procedures in
this section to replace a cache module in either single or dual-redundant controller
configurations.
Caution: With ACS V8.7, V8.7-1, and V8.7-2, FRUTIL allows you to install
both the controller and cache module in the same process. HP does not
recommend this. Replacing both the controller and cache module at the same
time can result in loss of controller configuration information and will render
the controller unusable.
Note: With ACS V8.7-3, FRUTIL prohibits you from installing both the controller and
cache module in one process.
This section contains the following topics:
■ Replacing HSx80 Cache Modules in Single Controller Configurations,
page 36
■ Replacing HSx80 Cache Modules in Dual-Redundant Controller
Configurations, page 41
Note: In dual-redundant configurations, both cache modules must contain the same
memory configuration, regardless of the ACS version.
