CLI Command Descriptions
• Specify NODESTROY_UNFLUSHED_DATA to retain the cached data and
discard controller information. The controller metadata synchronizes with the
cache module data and preserves any unwritten data for eventual flushing to
the disk array.
The NODESTROY_UNFLUSHED_DATA parameter is used in the following
situations:
• If the controller module has been replaced.
• If the controller nonvolatile memory (NVMEM) contents were lost.
The DESTROY_UNFLUSHED_DATA parameter is used to retain the controller
information and discard unwritten cache data in the following situations:
• If the cache module has been replaced.
• Any other reason not listed above.
CAUTION: Specifying the DESTROY_UNFLUSHED_DATA parameter destroys data
remaining in cache, which can result in data loss.
