Error description
PowerHA 7.1.3 clusters which have been created on AIX 7.2.1 are unable to change the network_fdt tunable, e.g.: root@ha1clB:/ # oslevel -s 7200-01-01-1642 root@ha1clB:/ # halevel -s 7.1.3 SP6 root@ha1clB:/ # clctrl -tune -o network_fdt=30 clctrl -tune: 1485-506 The current cluster level does not support tunable network_fdt. because the effective CAA level is 30000: root@ha1clB:/ # lscluster -c \ | grep -e "capabilities:" -e "level:" Local node maximum capabilities: SPLT_MRG, CAA_NETMON, AUTO_REPOS_REPLACE, HNAME_CHG, UNICAST, IPV6, SITE Effective cluster-wide capabilities:, HNAME_CHG, UNICAST, IPV6, SITE Local node max level: 50000 Effective cluster level: 30000 The same applies to PowerHA 7.2.0 when the PowerHA configuration had no backup repository defined at the time the CAA cluster has been created. Please note, that also CAA netmon is disabled if the 'Effective cluster level' is set to 30000.
Local fix
PowerHA 7.2.0: Remove and recreate the cluster with a backup repository definition. There is no workaround for PowerHA 7.1.3.
Problem summary
Cannot use clctrl -tune to change network_fdt on AIX 7.2
Problem conclusion
Add auto_repos_replace to capabilities if supported when creating cluster with cldare
