This change enables only string ciphers for communication between engine and hosts for clusters with cluster level >= 4.2.
Following steps need to performed to apply the change:
1. Newly added hosts
- The change is applied automatically when host is added to engine to clusters with cluster level >= 4.2
- When adding new host to cluster with cluster level 3.6, 4.0 or 4.1 the change is not applied and hosts support all ciphers enabled by underlying libraries
2. Existing hosts
- to apply the change to existing hosts in cluster level 4.2 please follow steps described in [How to apply change] section
3. Moving hosts between clusters
- when host is moved to 4.2 cluster the change is not applied automatically. To apply please follow steps described in [How to apply change] section
How to apply change
To enable only strong ciphers for a host in cluster with cluster levels >= 4.2 following steps need to be applied:
1. Move host to Maintenance using option Maintenance in Management menu inside Hosts view
2. Reinstall the host using option Reinstall in Installation menu inside Hosts view
