Cause

Aucun package MDM n’était installé sur le nœud en veille.

Resolution

Supprimez le nœud en veille :

#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.
