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
Issue #5021 remoteshell postscript: sshd_config KeyRegenerationInterval option deprecated as of OpenSSH 7.4
Issue #5142 updatenode without options causes command to crash
Issue #5257 openbmc python agent exited unexpectedly
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
