NEW xCAT Documentation

xCAT documentation has been refined and is now hosted at https://xcat-docs.readthedocs.org. Please use the new documentation and open any issues on GitHub. The original documentation is still left around on SourceForge as a reference.

Restrictions and Known Problems

• Issue #471: Firmware Update using xCATs rflash command is not stable enough to select accurate delay time after issuing a reset cold and starting the firmware update on IBM Power S822LC systems. If rflash fails, modify the rflash_delay attribute in site table to adjust the delay time. The default value is 120 seconds and we suggest setting this value to 70 and retry.

• 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"
  

• 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
