Test Environment

Key Bug fixes

Restrictions and Known Problems

  • The perl-Net-DNS-0.73-1.28 shipped with SLES 12 has one bug that causes makedns could not work, see xCAT bug 4331 for more details. We are working with SuSE to update the perl-Net-DNS package in SLES, as a temporary solution, xCAT compiled and shipped an updated version of perl-Net-DNS that fixed the known problem in xcat-dep, the Perl-Net-DNS package shipped with xcat-dep is perl-Net-DNS-0.80-1, you need to update the perl-Net-DNS to the version shipped with xcat-dep manually, if the update was not done.
  • On stateless x86_64 Ubuntu 14.04.01 compute nodes, "cat /etc/*release*" lists Ubuntu 14.04, the workaround is to check the kernel version to verify if the statless node is Ubuntu 14.04 or 14.04.01.
  • DFM on AIX does not support IBM Power 8 machines.
  • In DFM configuration, the following rspconfig options are not working when site.enableASMI is set to yes: memdecfg decfg procdecfg iocap time date autopower sysdump spdump network dev celogin1. These options need to go through ASMI web interface, there are some major problems in the code logic to support the ASMI web interface.
  • If there are x86_64 KVM or PowerKVM guests in the xCAT cluster, the perl-Sys-Virt is required to be installed manually on the management node to enable hardware control capabilities against the virtual machines. See bug 4344 for more details.
  • kdump on rhels7 ramdisk-based statelite is not supported
  • For Ubuntu 14.04 and 14.10, the diskful provisioning and diskless genimage will need internet connections to download additional packages from internet Ubuntu repo, this is definite requirement for now, we will investigate if it is possible to eliminate this requirement in some later release.
  • Redhat 7 deployment on Power 7 platform sometimes fail with "error: connection timeout.", the workaround is to change the linux kernel and initrd download method from "http" to "tftp" in grub2. See 4406 for more details.
  • If there are quite a few(e.g. 12) network adapters on the SLES compute nodes, the os provisioning might hang because that the kernel would timeout waiting for the network driver to initialize. The symptom is the compute node could not find os provisioning repository, the error message is "Please make sure your installation medium is available. Retry?". See bug 4462 for more details.

To avoid this problem, you could specify the kernel parameter "netwait" to have the kernel wait the network adapters initialization. On a node with 12 network adapters, the netwait=60 did the trick.

chdef <nodename> -p addkcmdline="netwait=60"
  • The xCAT postscripts may not be able to run when provisioning SLES 12 on x86_64 platform, the symptom is that after the os provisioning is done, the node status is still "booting", and the node could not be logged in through ssh. The workaround is to login the node through console and run "service sshd start", and then run xdsh <nodename> -K", and then "updatenode <nodename> -P". See bug 4463 for more details.

  • On Ubuntu 14.x, the command 'lsdef <node> -i status' sometimes can NOT return the correct value for the status attribute. This issue also impacts the attributes which are stored in the nodelist table. Refer to the bug 4468 for more details.

  • The Postscripts otherpkgs didn't support on sles12. Refer to the bug 4482 for more details.
