 Issue:

Create resource Pool and vApp option is disabled

Solution:

For enabling vApp to Resource Pool in vCenter server, HA cluster and DRS should be enabled.

1. Connect to your vCenter Server web client. Make sure that a cluster is created.

2. Go to Hosts and Clusters, select your cluster, open the Manage tab, then open the Settings tab, and select Services > vSphere DRS.

3. In the opened Edit Cluster Settings window, tick the Turn On vSphere DRS checkbox, and set DRS automation, power management, and advanced options if needed.
