Upon host/guest upgrade, vCMP guest is 'Inoperative'.


-- Isolated vCMP guest. -- Both 'Address' and 'Alt-Address' are assigned the same IPv4 address. -- Upgrade occurs.


-- For new vCMP guests, or prior to booting the vCMP guest to an affected version for the first time, assign it a management-ip from the vCMP host. This prevents the alt-address from being assigned and the issue from occurring on subsequent upgrades. tmsh modify vcmp <guest_name> management-ip -- For existing vCMP guests already on an affected version, but not currently experiencing the issue, assign a management-ip from the vCMP host and remove the alt-address from within the vCMP guest to prevent the issue from occurring in a future upgrade or reboot: host# tmsh modify vcmp guest <guest-name> management-ip guest# tmsh modify sys cluster default alt-address none -- When already upgraded and seeing the issue on a guest, set a management-ip from the vCMP host and run the following commands within the guest to remove the alternate address from the configuration file: host# tmsh modify vcmp guest <guest-name> management-ip guest# bigstart stop clusterd guest# sed -i s/alt_addr=.*// -i /shared/db/cluster.conf guest# bigstart start clusterd
