Restrictions and Known Problems

• RHEL 6.2 diskless boot on the IBM Flex system p compute nodes might be kernel panic with error "dracut Warning: No root device "1" found". It is caused by the upper case characters in the nodes' mac attribute, we are still working with Linux team to figure out the reason, for now, the Workaround is to change the nodes' mac attribute to be lower case characters. For details see: https://sourceforge.net/tracker/?func=detail&aid=3535481&group_id=208749&atid=1006945
• updatenode -k does not work to compute nodes. To update ssh key to compute node, use xdsh -K command. To update hostkeys on the compute nodes, use xdcp or pscp to copy /etc/xcat/hostkeys directory to the /etc/ssh directory on the node. https://sourceforge.net/tracker/?func=detail&aid=3537905&group_id=208749&atid=1006945
• xcat upgrade of xcat-rmc rpm fails, if /install directory is local mounted directory or mounted on service node. Workaround is to force install the rpm. See https://sourceforge.net/tracker/index.php?func=detail&aid=3538372&group_id=208749&atid=1006945
• intirid fail to mount rootimg on sles11.2 x86. This is a sles11.2 bug and a bugzilla reported opened. Work-around and details of the problem documented in https://sourceforge.net/tracker/?func=detail&aid=3558922&group_id=208749&atid=1006945
