PreviouslyPublishedAs 238626 Bug Id <SUNBUG: 6683763>, <SUNBUG: 6667692> Date of Preliminary Release 10-Jun-2008 Date of Resolved Release 16-Sep-2008 Product Sun SPARC Enterprise M9000 Server Sun SPARC Enterprise M8000 Server Active replacement of XSCF can lead to unit fault (see details below). Affected Parts: 371-2228 eXtended System Control Facility Unit B, XSCF_B, RoHS:Y 371-2229 eXtended System Control Facility Unit C, XSCF_C, RoHS:Y ImpactDuring an active replacement of a XSCF Unit (XSCFU) using "replacefru" you run the risk of causing the new XSCF Unit to become unusable. This is due to a timeout of the database sync. Once the XSCFU is in this state it is not possible to fix it in the field and the XSCFU would require replacement.Contributing FactorsThis issue can occur on either of the above listed Affected Parts if the replacefru command is used to active replace an XSCF Unit when XCP Firmware is equal to or less than 1071.SymptomsThe following are examples of what you will see via showstatus reports when this issue occurs;XSCFU_B#0 Status:Faulted or XSCFU_B#1 Status:Faulted Root CauseUsing the replacefru command to carry out an active replacement on the XSCFU board can take too long causing a timeout during the database sync of the two XSCF Units.For details refer to BugIDs 6683763 and 6667692. Corrective ActionWorkaround:XCP releases below 1072: Customers may elect to use cold swap to immediately replace a failed XSCF Unit. This requires a full platform outage with all domains down. The breakers must also be switched off to eliminate power to the XSCF Units. Customers may also elect to defer the replacement of a failed XSCF Unit until a firmware fix is available to utilize active swap. Domains will not be impacted with active swap. Deferring the replacement of the failed XSCF Unit would run the platform in a non-redundant XSCF configuration. This process is documented in the Sun SPARC Enterprise M8000/M9000 Servers Service Manual. The COLD replacement process is documented in section 11.3. You should also check the firmware of the replacement XSCF per section 8.1.10 of the Sun SPARC Enterprise M4000/M5000/M8000/M9000 Servers XSCF User's Guide. All documentation for these products can be found at: Resolution: Install XCP firmware 1072 (or later) which can be downloaded from the Oracle download site.
