Chapter 4 FRU Removal Preparation 4-3

be replaced. Active replacement has four stages:

■ Section 4.2.3, “Configuring a FRU into a Domain” on page 4-6
■ Section 4.2.4, “Confirming the Hardware” on page 4-7

support software can disconnect the relevant boot disk from Solaris OS, active
replacement can be performed.
