Key Issues Resolved

Restrictions and Known Issues

If deploying RHEL8 compute nodes after upgrading from a previous xCAT installation, the install of RHEL8 may hang and not complete without much reason given back to the user. This is related to the following issues: #5794 #5798 #6061 #6090

The root cause of this is TLSv1 has been deprecated and unsupported in RHEL8. To check if you are hitting the issue tabdump site | grep xcatsslversion and see if TLSv1 is configured. If so, unset it: chdef -t site xcatsslversion=.

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
