Highlighted Functions

    • Resolved an issue that causes 100% CPU utilization when rflash is called. [Issue #5176]

  • 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]

Key Issues Resolved

Issue #4248 When booting into xCAT genesis shell, the status should be updated to be consistent

Issue #4855 Python error message for bmcstate needs to match Perl - blocker

Issue #5006 Check DD versions before attempting rflash

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
