Ao tentar substituir um nó do MDM escravo por um nó em espera, obtendo-se o seguinte erro no registro de eventos:

O comando usado foi:

#scli --replace_cluster_mdm --add_slave_mdm_name Manager2 --remove_slave_mdm_name Manager3 --allow_leave_failed --i_am_sure

#scli --query_cluster

Cause

Não havia nenhum pacote MDM instalado no nó em espera.

Resolution

Remova o nó em espera:

#scli --remove_standby_mdm --remove_mdm_name Manager2

Install the MDM package on the standby mode - for svm: 

#MDM_ROLE_IS_MANAGER=1 rpm -i < package >

Add the standby node back to the cluster:

#scli --add_standby_mdm --mdm_role manager --new_mdm_ip x.x.x.x,x.x.x.x --new_mdm_name Manager2 --new_mdm_management_ip x.x.x.x

Then run the '--replace_cluster_mdm ' command again.
