Removing member from ClusterXL

[JayM1]

Hi All,

I have a pair of 3920 gateway appliances in a clusterXL setup and want to remove one of them to use elsewhere.  

Whats the best way to remove without causing an outage, issues with policy pushes and sync issues ?

Please follow this SK:

Or as a reference the admin guide, SK sounds better to me tbh. Any cases would recommend window

Will I need to login to active member and disable cluster membership there as well and reboot?

It depends on the situation.

If the gateway will operate as a standalone, disable cluster membership in cpconfig and reboot it.

Otherwise these issues might appear:

• Policy installation may fail with errors about cluster membership.
• Features like Static NAT may not work correctly.
• The gateway may not function properly as a standalone device.
  

  
  Disabling cluster membership modifies how the gateway's kernel modules and Check Point services operate.
  ClusterXL and related high-availability modules are loaded at boot time. Disabling cluster membership removes these modules from the boot process. A reboot ensures that all cluster-related processes and kernel modules are fully unloaded and that the gateway starts in standalone mode.

If the gateway will be added shortly to another cluster you can keep cluster membership active in cpconfig.
