Highlighted Functions

  • OpenBMC support

  • For hardware discovery

    • The beta version of xCAT-genesis-base-x86_64 build on centos7 is available at rpm/deb, they have included all drivers shipped by Centos7.
      Notes to use xCAT-genesis-base-x86_64 1. before install it, you shall remove the xcat-genesis-scripts-x86_64/amd64 and old xcat-genesis-base-x86_64/amd64_2.13.2. Then, install xcat-genesis-base-x86_64/amd64_2.13.9 package above and reinstall xcat-genesis-scripts-x86_64/amd64. 2. pls run `mknb x86_64` after install.

  • Constellation PDU support

  • Add Q/A for DNS, hostname, alias configuration

  • goconserver to provide remote access to system consoles

    • the goconserver daemon v0.1.0 for accessing system consoles is available at https://github.com/chenglch/goconserver/releases

    • integrate with xcat interface rcons, makegocons

      Technical Preview for goconserver(Beta) feature If you would like to try goconserver(beta) - the new lightweight console server of xCAT, follow the steps below:
      • Stop and disable conserver service on MN and all service nodes
      systemctl stop conserver
systemctl disable conserver
      • Download the latest goconserver package and install it on MN and all service nodes
      wget https://github.com/chenglch/goconserver/files/1558246/goconserver-0.1.0-snap201712140221.ppc64le.rpm.tar.gz
tar xvfz goconserver-0.1.0-snap201712140221.ppc64le.rpm.tar.gz
yum install goconserver-0.1.0-snap201712140221.ppc64le.rpm

      And you could add this package into otherpkgs list of the osimage for service node.

      • Define your compute node with as normal, and using makegocons to register compute nodes into goconserver. Then you could use rcons to access the console.
      # chdef cn01 conserver=sn01
# makegocons cn01
cn01: Created

# rcons cn01
      • Unregister the console for compute nodes
      makegocons -d cn01

      Known Issue:

      • Failed to start goconserver on service node, You could copy the certificate files to serivce node for a workaround.
      xdcp service /etc/xcat/cert/* /etc/xcat/cert/
makegocons cn01
      • Failed to register compute node into goconserver. If you start goconserver service before you running makegocons, /etc/goconserver/server.conf may not be generated successfully. You can workaround it with below steps:
      systemctl stop goconserver
makegocons cn01
      • conserver is started on service node when restarting xcatd (node reboot, xCAT upgrade, etc), and it will cause duplicate console session for compute nodes. Just to stop conserver manually.
      systemctl stop conserver

      Note: To switch back to conserver, just follow below steps:

      makegocons -d
systemctl stop goconserver
systemctl start conserver
systemctl enable conserver
makeconservercf
