XCAT_2.12.2_Release_Notes - xcat2/xcat-core GitHub Wiki

New Functions and Changes in Behavior

Features

New OS Support

  • Ubuntu 16.04.1

    • Install xCAT on Ubuntu 16.04.1
    • Install Ubuntu 16.04.1 in diskful/diskless Compute nodes

New Arguments

  • packimage [-m|--method cpio|tar] [-c|--compress gzip|pigz|xz] imagename

    Add two new options to specify the archive method and compress method for packaging the diskless OS image. Resolves Issue #922

New Functions

  • nodeset <noderange> offline

    Enhanced the offline option for nodeset that allows for de-configuration of the nodes specified by the <noderange>.

  • Correctly update the status field when running rpower commands

    The status attribute of nodes will be updated immediately after successfully running of command rpower <noderange> on/off/reset

  • xcatprobe - A command to probe/diagnose potential problems with xCAT (BETA)

    • osdeploy - sub command for xcatprobe allows for a replay of the operating system deployment process

      xcatprobe osdeploy -n <noderange> -r 30m replays the OS deployment activity in the past 30 minutes for the compute nodes specified by the ` attribute.

  • Add support for bonded NICS during the xCAT hardware discovery process

    xCAT discovery process now supports configuration of the MAC addresses for two NICS in the mac attribute for the discovered nodes. This helps the operating system deploy successfully using either of the two active NICS on the install network when bonding is being used.
