Cache Module Memory Configuration
—The
replacement cache module normally uses DIMMs from the
cache module being replaced. When replacing DIMMs,
you
must
install DIMMs in the replacement cache module
in same position as they were in the cache module that is
being replaced.
General information
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.
Note:
In dual-redundant configurations, both cache modules
must
contain the same memory configuration, regardless of the ACS
version.
Figure 1
and
Figure 2
(on page 2) provide general information
about the cache module.
Note:
See
Figure 1
and
Figure 2
(on page 2) for specific
component references while replacing cache modules.
