NetScaler Pooled Capacity on NetScaler Instances in High Availability mode

Jun 23, 2017

You can configure NetScaler Pooled Capacity on the NetScaler instances configured in high availability mode, on a new NetScaler HA pair or an existing HA pair. When a fail over happens, the secondary instance in a HA Pair checks-out the same capacity that was present in the primary instance.

To migrate an existing HA setup to NetScaler pooled capacity

1. Remove the existing platform licenses and warm restart both instances to make them unlicensed.

2. For an MPX instance, add NetScaler Pooled Capacity Platform license on both the instances.

3. On the Configuration tab, navigate to System > Licenses > Manage Licenses, click Add New License and select Use Pooled Licensing.

6. Warm reboot both the instances. 


If you try to use NetScaler Pooled Capacity with the existing platform licenses on a VPX instance, the following error message appears in the NetScaler GUI.
