Package Installation in Clusters

When all Cluster Members are marked for installation in the Candidates List, the CDT upgrades all Cluster Members automatically:

  • In ClusterXL High Availability mode - the CDT first upgrades the Standby members, and then the CDT upgrades the former Active member.

  • In VRRP Cluster - the CDT first upgrades the VRRP Backup member, and then the CDT upgrades the former VRRP Master member.

  • In VSX Virtual System Load Sharing (VSLS) cluster - the CDT first upgrades all the members listed as VSLS member in the Candidates List, and then the CDT upgrades the member listed as the VSLS active member in the Candidates List.

CDT and the cluster Connectivity Upgrade:

For version upgrades (not installation of Hotfixes), the CDT runs the cluster Connectivity Upgrade (CU) by default. Meaning that the connections are synchronized between the Cluster Members.

If you wish to disable this behavior, follow the instructions below:
