About this task

ESXi resource pools must be configured so Discovery can identify virtual machines and their relationships correctly. Resource levels are dynamically generated from shares of the total resources allocated to virtual machines on the ESXi server. For details about how these resources are calculated, review the VMware knowledge base https://www.vmware.com/. ServiceNow Discovery finds this default resource pool and adds a record to the ESXi Resource Pools module automatically.

If Discovery isn't running on the ServiceNow instance, create a record for the Resources pool. Verify that the Owner field is correct and leave the resource fields empty. If a provisioner selects the Resources pool when provisioning a virtual server, the ESXi server creates a virtual machine for use under a normal load.

Procedure

1. Navigate to All > VMware Cloud > Configuration > ESX Resource Pools.
2. Select New in the list.
3. Create a record for each resource pool in the ESXi server, verifying that the Name and Owner fields are correct.
4. Select the CPU expandable and Memory expandable check boxes.

   These features enable for expansion of the CPU and memory limits when needed, if those resources are available on the ESXi server. When granted, these extra resources can be revoked to provision other virtual machines. The additional fields on the form are for display purposes only.

5. Select Submit.
