Test Environment

xCAT dependency package verified with this xCAT release:

Operating Systems which have been verified:

  • RHEL 7.2 LE
  • Ubuntu 14.04.03

Hardware Platform which have been verified:

  • IBM Power Systems S822LC

Restrictions and Known Problems

  • RHEL 7.2 LE is not yet GA so xCAT does not have the GA ISO identifier to add to copycds.

    Work around: Use the -n option to specify the name when running copycds:

     # copycds -n rhels7.2 <path_to_iso_file>.iso

  • Firmware Update using xCAT rflash is not available at this time

    Work around: Update the firmware directly using ipmitool 1.8.15

  • Issue #71: The package util-linux cannot be upgraded to latest version in Ubuntu 14.04.3 diskless systems. The root cause is a dependency of this package has been changed.

    Work around: Run the apt-get dist-upgrade by yourself after doing a chroot into the rootimgdir.

  • Issue #274: RHEL 7.2 diskless image cannot be booted up.

    Work around: disable (or blacklist) the nvidiafb driver by adding to the modprobe.blacklist:

     # chdef <noderange> -p addkcmdline="modprobe.blacklist=nvidiafb"

  • Issue #236: The function to set the IP address of the BMC using the rspconfig for IBM Power System S822LC does not work.

    Work around: Recycle the power of the server after the IP address has been changed using the rspconfig to have the IP take effect.

  • Issue #233: Output messages from rinv needs to be supported/corrected

  • Issue #234: Output messages from rvitals need to be supported/corrected

  • Issue #398: Install OFED fail for diskful compute node.
