VCMP host or guest is upgraded, and the vCMP guest is 'Inoperative', with messages similar to the following in /var/log/ltm: -- warning clusterd[1546]: 013a0005:4: Clusterd using /VERSION for SW specification. -- info clusterd[1546]: 013a0023:6: Blade 1: No info received from slot: Starting up -- err clusterd[1546]: 013a0004:3: result { -- err clusterd[1546]: 013a0004:3: result.code 17237812 -- err clusterd[1546]: 013a0004:3: result.attribute float_mgmt2_ip -- err clusterd[1546]: 013a0004:3: result.message 01070734:3: Configuration error: Cluster alt-address: 192.168.1.246 cannot be the same address family as cluster address: 192.168.1.246 -- err clusterd[1546]: 013a0004:3: } -- err clusterd[1546]: 013a0004:3: Per-invocation log rate exceeded; throttling. -- notice clusterd[1546]: 013a0006:5: Disconnecting from mcpd. -- info clusterd[1546]: 013a0007:6: clusterd stopping...

Impact

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

Conditions

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

Workaround

-- 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 192.168.1.246/24 -- 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 192.168.1.246/24 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 192.168.1.246/24 guest# bigstart stop clusterd guest# sed -i s/alt_addr=.*// -i /shared/db/cluster.conf guest# bigstart start clusterd
