Symptoms

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

There are 3 workarounds: -- Assign IPv4 management-ip for the guest PRIOR to upgrade: tmsh modify vcmp <guest_name> management-ip <ip>/<mask> -- Prior to upgrade, assign IPv6 'Alt-Address' within the guest: tmsh modify sys cluster default alt-address <IP>/<mask> -- When already upgraded and seeing the issue on a guest: execute: > /shared/db/cluster.conf The config loads, and /shared/db/cluster.conf is recreated: cat /shared/db/cluster.conf cluster default { alt_addr="192.168.1.246/24" ====> min_up_members="1" min_up_members_enable="disable" min_up_members_action="failover" addr 192.168.1.246/24 ====> members { 1 2 3 4 } software HD1.1 "BIG-IP 14.1.0.3 0.0.6 0.0.6" true software HD1.2 " " false software HD1.3 " " false }
