  • Supported to add additional kernel parameters for diskful deployment.

    • Supported on Ubuntu, Redhat and SLES.
    • The new added kernel parameters can be persistent during reboot.
    • See "set the kernel options which will be persistent the installed system" section of Installing_Stateful_Linux_Nodes for Details.

  • Added command 'switchdiscover' to support the discovery of Enthernet and IB switches. Refer to the man page of switchdiscover command.

  • Made the change that "copycds" only creates diskful and diskless osimages for compute and service nodes.

  • non-osimage features have been deprecated in xCAT 2.10, you could not run nodeset install|netboot|statelite for RHEL, SLES and Ubuntu nodes any more. See documentation Convert Non-osimage Based System To Osimage Based System for more details on how to convert to osimage based configuration.
