2.12. Example: Attaching Storage Domains to a Data Center using Python

Once you have added storage domains to Red Hat Enterprise Virtualization you must attach them to a data center and activate them before they will be ready for use.

Example 2.11. Attaching storage domains to a data center using Python

This Python example attaches a data storage domain named data1, and an ISO storage domain named iso1 to the default data center. The attach action is facilitated by the add method of the data center's storagedomains collection. 
from ovirtsdk.api import API
from ovirtsdk.xml import params

try:
    api = API (url="https://HOST",
               username="USER@DOMAIN",
               password="PASS",
               ca_file="ca.crt")

    dc = api.datacenters.get(name="Default")

    sd_data = api.storagedomains.get(name="data1")
    sd_iso = api.storagedomains.get(name="iso1")

    try:
        dc_sd = dc.storagedomains.add(sd_data)
        print "Attached data storage domain '%s' to data center '%s' (Status: %s)." % 
		      (dc_sd.get_name(), dc.get_name, dc_sd.get_status().get_state())
    except Exception as ex:
        print "Attaching data storage domain to data center failed: %s." % ex

    try:
        dc_sd = dc.storagedomains.add(sd_iso)
        print "Attached ISO storage domain '%s' to data center '%s' (Status: %s)." % 
		      (dc_sd.get_name(), dc.get_name, dc_sd.get_status().get_state())
    except Exception as ex:
        print "Attaching ISO storage domain to data center failed: %s." % ex

    api.disconnect()
    
except Exception as ex:
    print "Unexpected error: %s" % ex
If the calls to the add methods are successful then the script will output: 
Attached data storage domain 'data1' to data center 'Default' (Status: maintenance).
Attached ISO storage domain 'iso1' to data center 'Default' (Status: maintenance).
Note that the status reflects that the storage domains still need to be activated.
