4.2.2 Replacing a BBU (for Dorado6000 V3)
This section describes how to replace a BBU.
Impact on the System
l Replacing a BBU affects data security.
l During the replacement, if all other BBUs fail, the system is no longer BBU-protected.
To enhance data security, the system forcibly implements LUN write protection, and the
system performance is compromised.
Prerequisites
l The spare part is ready.
l Configuration data has been backed up.
l The BBU that you want to replace has been located.
