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:
In the CDT primary configuration file (see The CDT Primary Configuration File), add the <PackageToInstall>
element, with both the attribute Path="..."
and the attribute ConnectivityUpgrade="false"
:
|
In the Deployment Plan file (see Deployment Plan), in the element <plan_settings>
, add the attribute <ConnectivityUpgrade value="false" />
(see Example 5 - Run a Script, Uninstall a Hotfix, Upgrade, Install a Hotfix, Log and Send Email, Pull a File).

When you upgrade to R77.30 or R80.20, there are two options:

Run the Connectivity Upgrade:
Example for a Security Gateway R80.20 (the instructions contain four lines):
|
-
In ClusterXL High Availability mode - You cannot upgrade the ClusterXL Active member before you upgrade all the ClusterXL Standby members.
-
In VRRP Cluster - You cannot upgrade the VRRP Master member before you upgrade the VRRP Backup member.
-
In VSX VSLS cluster - You cannot upgrade the cluster member listed as VSLS Active member in the Candidates List before you upgrade the cluster members listed as VSLS member in the Candidates List.
-
In ClusterXL High Availability mode - If the upgrade of the ClusterXL Standby members fails.
-
In VRRP Cluster - If the upgrade of the VRRP Backup member fails.
-
In VSX VSLS cluster - If the upgrade of the cluster members listed as VSLS member in the Candidates List fails.
If the installation on the first Cluster Member succeeds, but the installation on the other Cluster Members fails, the CDT does not revert the first Cluster Member.
