Solution Type FAB (standard) Sure Solution 1018991.1 : SPARC Enterprise M4000/M5000/M8000/M9000 servers should be updated to a minimum of Solaris 10 08/07 and XCP 1061 for Relaxed Ordering and other Bug Fixes.
PreviouslyPublishedAs 231561 Bug Id <SUNBUG: 6594903> (see full list in Comments section) Product Sun SPARC Enterprise M4000 Server Sun SPARC Enterprise M5000 Server Sun SPARC Enterprise M8000 Server Sun SPARC Enterprise M9000 Server Date of Resolved Release 12-Feb-2008 SPARC Enterprise M4000/M5000/M8000/M9000 servers should be updated to a minimum of Solaris 10 08/07 and XCP 1061 (see below for details). ImpactSystems not updated to Solaris 10 08/07 and XCP 1061 will not be able to take advantage of certain platform features, may experience potential performance issues, may experience "disk full" related reboots on their eXtended System Control Facility Unit (XSCF) which can lead to XSCF replacement, and may not benefit from bug fixes included in the newer release of software.Contributing FactorsSun SPARC Enterprise M4000, M5000, M8000 and M9000 systems below Solaris 10 08/07 and XCP 1061 are impacted.Functionality added to later releases of software may not be backported to earlier versions. This functionality includes features such as DR/Hotplug. The implementation of some performance improvements which are bundled with Solaris 10 08/07 are shipped as many different patches to Solaris 10 11/06 which can lead to confusion and incomplete implementations. This is especially true for the Relaxed Ordering features for IO cards. Symptoms. Lack of functionality as described above. Reduced IO performance . XSCF replacements due to reboot counter limits being exceeded Root CauseSolaris 10 08/07 introduced full support for features such as Dynamic Reconfiguration (DR) and IO Hotplug. It also included built-in support for cards using the nxge driver such as Quad Gigabit and Dual 10-Gigabit Ethernet required for some higher performance network cards along with Relaxed Ordering fixes for improved IO performance from all Sun supported IO cards on the Sun SPARC Enterprise server line. While some fixes (namely for Relaxed Ordering) are available as patches to the older Solaris 10 11/06 OS release, features such as IO Hotplug and full support for Dynamic Reconfiguration are not.Systems running releases prior to XCP 1061 may experience "disk full" issues. The "disk full" condition can cause the XSCF to reboot multiple times causing the reboot counter to reach it's limit and require XSCF replacement. Corrective ActionWorkaroundThere are no workarounds to the reduced DR and IO Hotplug functionality, or to the XSCF "disk full" condition.For bug fixes and Relaxed Ordering, customers may apply a number of patches to Solaris 10 11/06 to gain some functionality included in Solaris 10 08/07. Certain drivers, in particular the e1000g driver used on Sun Dual Gigabit Ethernet cards, do not have patches available and require Solaris 10 08/07 and XCP 1050 or higher in order to enable Relaxed Ordering. ResolutionSystems should be upgraded to at least Solaris 10 08/07 and XCP 1061 in order to receive all possible fixes.Identification of Affected Parts (how to): For Solaris, systems with an /etc/release indicating the following are impacted: Solaris 10 11/06 s10s_u3wos_10 SPARC For the XSCF, check version -c xcp output. An example is given below: XSCF> version -c xcp XSCF#0 (Active ) XCP0 (Current): 1041 XCP1 (Reserve): 1041 XSCF> If version -c xcp does not return 1061 or higher, the system is affected. Information on performing an XCP 1061 upgrade can be found in the XCP 1061 product notes available on; http://www.sun.com/downloads/products.xml?id=46fc425e The documentation from the download center comes in several parts. The README_1061_en.txt file refers you to the installation instructions. Reference Chapter 8 in "SPARC Enterprise M4000/M5000/M8000/M9000 Servers XSCF User's Guide". Chapter 8 is "Upgrade of XSCF Firmware and Maintenance". The file README lists all related bug fixes included in 1061. It also points out that this minor release does not call for a rewrite of documentation. No new or updated documentation is available to XCP1061 besides this README file. All documentation released for XCP1060 is still relevant and should be used for this release.
