To remove the component:
1. Determine if the controller configuration supports hot-plug cache
replacement:
−
If the storage system is equipped with a single controller, power down
the storage system (on page

different capacity than the failed cache, power down the storage system
(on page
9 ).
−
If the system has redundant controllers and the replacement cache is the
same capacity as the failed cache, proceed with step 2.
2. Remove the controller ("Modular Smart Array 500 Generation 2 Controller"
on page 13 ).
3. Remove the existing cache module.
4. Repeat steps 2 and 3 if the storage system has redundant controllers and the
replacement cache is a different capacity than the failed cache.
