Key Issues Resolved

Issue #5517 Comma-separated syncfiles lists not supported by packimage

Issue #5454 rflash -d <dir> option fails to reboot Node Host/OS that is up/running

Issue #5436 xcatd starts conserver instead of goconserver on SNs

Issue #5276 rflash slow to respond and two operations can hang

Issue #5299 rflash over a range using the directory option, ends early with no reason

Issue #5312 rflash can not display error if firmware file upload has failed

Issue #5118 SLES12.3 supporting issue

Issue #4014 Command makedhcp failed silently when invalid mac address is used in node definition

Issue #3854 CentOS7: missing wget in installation chroot blocks postinstallationscripts

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
