How to mount purestorage volume as a VMware datastore in vCenter using python?

Question

I have purestorage volume and vcenter in my environment. As i want to add/provision purestorage volume as a datastore in vmware vcenter using python script using python pyvmomi package. Its not working as expected.

I tried the below using pyvmomi python package, but it is not working as expected

from pyVim.connect import SmartConnect, Disconnect
from pyVmomi import vim
import purestorage
import requests
from urllib3.exceptions import InsecureRequestWarning
requests.packages.urllib3.disable_warnings(category=InsecureRequestWarning)

import ssl

s=ssl.SSLContext(ssl.PROTOCOL_TLSv1)
s.verify_mode=ssl.CERT_NONE



def add_pure_volume_as_datastore():
    # Pure Storage array details
    pure_array = '192.168.0.106'
    pure_api_token = '125cfec6-560a-ca26-e7af-27be4234d3959'
    pure_array_name = 'purefa1.lab.local'
    pure_vol_name = 'ds-vm-01'

    # VMware vCenter details
    vcenter_ip = '192.168.0.185'
    vcenter_user = '[email protected]'
    vcenter_password = 'admin@123'
    datacenter_name = 'dc'
    cluster_name = 'lab'
    esxi_hostname = 'esxi1.lab.local'
    port=443
    # Connect to Pure Storage array
    pure = purestorage.FlashArray(pure_array, api_token=pure_api_token)

    # Get volume information
    volume = pure.get_volume(pure_vol_name)

    # Connect to vCenter
    service_instance = SmartConnect(host=vcenter_ip, user=vcenter_user, pwd=vcenter_password, port=port,sslContext=s,disableSslCertValidation=True)
    
    print(vcenter_ip)
    # Get datacenter
    content = service_instance.RetrieveContent()
    datacenter = None
    for dc in content.rootFolder.childEntity:
        if isinstance(dc, vim.Datacenter) and dc.name == datacenter_name:
            datacenter = dc
            break

    if not datacenter:
        print(f"Datacenter '{datacenter_name}' not found.")
        return

    # Find the cluster
    cluster = None
    for c in datacenter.hostFolder.childEntity:
        if isinstance(c, vim.ClusterComputeResource) and c.name == cluster_name:
            cluster = c

    if not cluster:
        print(f"Cluster '{cluster_name}' not found.")
        return

    # Find the host
    host = None
    for h in cluster.host:
        if h.name == esxi_hostname:
            host = h
            break

    if not host:
        print(f"ESXi host '{esxi_hostname}' not found in cluster '{cluster_name}'.")
        return

    # Create a spec for the new datastore
    spec = vim.host.DatastoreSystem.CreateVmfsDatastoreSpec()
    spec.vmfs = vim.host.VmfsDatastoreCreateSpec()
    spec.vmfs.volumeName = volume['name']
    spec.vmfs.extent = [vim.host.VmfsDatastoreExpandSpec(
        devicePath=f'/vmfs/devices/disks/{volume["source"]["serial"]}:1',
        partition=None
    )]

    # Create the datastore
    host.configManager.datastoreSystem.CreateVmfsDatastore(spec=spec)

    # Disconnect from Pure Storage array and vCenter
    pure.invalidate_cookie()
    connect.Disconnect(service_instance)

if __name__ == "__main__":
    add_pure_volume_as_datastore()

while i am executing the above code . i am getting the error like below :
