4.2 FRU Replacement and Installation
Methods
This section explains how to replace and install FRUs.
4.2.1 FRU Replacement
There are three methods of replacing FRUs, as follows:
■ Active replacement
A target FRU is operated while the Oracle Solaris OS of the domain to which the
FRU belongs is operating.
The target FRU is operated by 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.
Note – The hard disk drive will have a redundant configuration by setting the
mirroring.
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. The hard disk replacement procedure varies by the
mirroring configuration method. When it is configured with hardware RAID, see the
SPARC Enterprise M3000/M4000/M5000/M8000/M9000 Servers Administration Guide.
When it is configured with software RAID, see the manuals for the software in use.
Note – Hardware RAID is available only on the M3000 server with the SPARC64
VII+ processors.
■ Hot replacement
A target FRU is operated while the domain to which the FRU belongs is stopped.
Depending on the target FRU, there are two cases as follows:
