Chapter 4 FRU Replacement Preparation 4-5
4.3 Active Replacement/Active Addition
In active replacement, the target FRU is operated while the Oracle Solaris OS of the
domain to which the FRU belongs is operating.
The target FRU is operated using Oracle Solaris OS commands or XSCF commands.
Because the power supply unit (PSU) and fan unit (FAN) do not belong to any
domain, they are operated by using XSCF commands regardless of the operating
state of the Oracle Solaris OS.
Active replacement has the following four stages:
■ “Releasing a FRU from a Domain” on page 4-5
■ “FRU Removal and Replacement” on page 4-6
■ “Configuring a FRU in a Domain” on page 4-6
■ “Verifying the Hardware Operation” on page 4-7
For active installation, see Section 4.3.3, “Configuring a FRU in a Domain” on
page 4-6 and "Section 4.3.4, “Verifying the Hardware Operation” on page 4-7.

Note – ■ If a hard disk drive is a nonmirrored boot device, it must be replaced
according to the cold replacement procedure.
■ If a hard disk drive is in a mirrored configuration, active replacement can be
performed on the failed drive because the mirrored hard disk drive continues to be
online and functioning.
