Highlighted Functions

• Cumulus Linux Switch OS

  • Allow syncfile to be used to distribute files to Cumulus Linux switches managed by xCAT. This is made possible by supporting osimage management on Cumulus Linux ISOs in xCAT. [mini-design]

• Hardware Discovery

  • Increased the size of the findme packet to allow for successful discovery of servers that contain large dataset of inventory. [Issue #5117]
  • Improved the discovery process by going to standby if nothing is specified in nextdestiny. [Issue #5098]

Restrictions and Known Issues

Issue #5121: rspconfig failed to set bmc ip etc in some specific condition

Issue #3513: For the latest xCAT-genesis-base, the mlx4_en driver 2.2-1 (Feb 2014) is included, it can not support Mellanox Ethernet NIC that need driver newer than 2.2-1, for more information, please reference build genesis locally with latest RH MN

Issue #5057: This issue cannot be reproduced, and the work around is : check the bmc state use rflash <node> -l, if the target firmware state is Active(+), execute rpower <node> boot to reboot the host and let new firmware take effect.

Issue #3284: While selinux on KVM host was reconfigured from enforcing to disabled, rpower failed to power previous created KVM guest on
