Applies to:

SPARC M5-32 - Version All Versions and later
SPARC M6-32 - Version All Versions and later
Oracle SuperCluster M6-32 Hardware - Version All Versions and later
Information in this document applies to any platform.

Goal

The purpose of this document is to summarize the Field Replacable Units (FRUs) in the SPARC Mx-32 hardware platform, and for each FRU list its type of replacement and if needed an explanatory note. The source of information for this document is the SPARC M5-32 and SPARC M6-32 Servers Service Manual . For more details related to servicing the Mx-32 hardware in general, and a specific FRU in detail, please visit the relevant sections of the SPARC M5-32 and SPARC M6-32 Servers Service Manual. This document can be used as a quick reference to find out which service method is to be used, given the system configuration and the FRU which requires service. If this document causes doubt or confusion, the SPARC M5-32 and SPARC M6-32 Servers Service Manual is leading.

Solution

Types of FRU replacement

Field Replaceable Units (FRUs) on the SPARC M5-32 and SPARC M6-32 Servers can be replaced using one of two possible replacement methods:

Cold Replacement :

Each FRU can be replaced through Cold Service replacement. Cold service replacement involves the entire platform to be powered off, including the removal from AC input power to the platform. If you do not power off the entire platform, then power off the Physical Domain (PDomain) that contains the FRU. The table below contains a note for each FRU, showing which other FRUs and PDomains are affected by the replacement.

Hot Replacement :

A number of FRUs can be replaced through Hot Service replacement. Hot Service FRUs can be removed while the PDomain(s) are running. Hot-swappable FRUs do not require any preparation prior to servicing, where as Hot-pluggable FRUs do require preparation prior to servicing. The method to prepare a FRU for removal can be different for each FRU. Preparation for removal includes one or more of pushing the Attention (ATTN) button, running software commands on the affected PDomains and running software commands on the active Service Processor (SP) . After physically replacing the FRU, it must be reconfigured back into its PDomain. The steps to reconfigure the FRU back into the PDomain include one or more of pushing the Attention (ATTN) button, running software commands on the affected PDomains and running software commands on the active Service Processor (SP). Any special consideration will be listed in a note for each FRU in the table below.

Before and after the actual hardware intervention

Before the actual FRU replacement takes places, it is the customer's responsability to take all necessary steps to make the FRU available for replacement.

What steps have to be taken depends on the chosen FRU replacement method. Hot FRU Replacement requires some preparation and sometimes requires one or more PDomains to be stopped, Cold FRU Replacement requires a lot of preparation and planning, and one of more PDomains need to be stopped.

How much time it takes to actually get tot the point where we can start the FRU replacement, or how much time it takes to stop and start affected PDomains, is very much depending on how the Mx-32 hardware is divided over the various DCU, and which DCUs make up which PDomain. Such stop and start times are out-of-scope for this document at this point in time, customers should have a fairly good idea as to how long it takes to stop and start their PDomains. Future version of this document might contain a few examples on PDomain stop and start times, but the best option will always be to rely on customer information.

What replacement method is available for this FRU ?

For each FRU, the document lists the FRU name, the available replacement methods, and if needed a specific note. If in doubt, please do consult the SPARC M5-32 and SPARC M6-32 Servers Service Manual, collaborate in the My Oracle Support Community - M Series Servers or contact Oracle Support.
