Battery-backed write cache procedures
Two types of procedures are provided for the BBWC option:
• Removal and replacement of failed components:
o Removing the cache module (on page 53)
o Removing the battery pack (on page 54)
• Recovery of cached data from a failed server ("Recovering data from the battery-backed write
