4-2 SPARC Enterprise M8000/M9000 Servers Service Manual • October 2012
4.1 Types of Replacement Procedures
The three types of replacement procedures explained below are supported for FRU
replacement. Choose the most suitable replacement procedure according to the customer's
system environment.
■ 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.
Note – 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 supported only on the M8000/M9000 servers on which a
RAID-capable onboard device card (IOUA) is mounted. The RAID-capable IOUA requires a
minimum XSCF firmware with applicable Oracle Solaris OS patches. See the latest Product
Notes for this information.
Note – When the onboard device card is RAID-capable, the showhardconf(8) command
displays Type 2 in the output.
