The NetAppRestError object is the standard exception that might be raised from the library whenever the server provides an error response to the client. An error response is any API request that returns a status code of >= 400. If you want your application to continue, you should handle the exception like any other in Python with a try/except block wrapped around the block of code that might throw an exception you want to handle.
Here is your code with a try/except that reports the error but keeps going:
from netapp_ontap import HostConnection, NetAppRestError
from netapp_ontap.resources import Volume, Snapshot
with HostConnection(hostname, username, password, verify=False):
vols = Volume.get_collection()
for volx in vols :
volx.get(fields='uuid,svm,name')
vservername = volx.svm.name
print(volx.svm.name)
snaps = Snapshot.get_collection(volx.uuid)
for snapx in snaps :
print(volx.name)
try:
snapx.get(fields='volume,snapmirror_label,create_time,name')
except NetAppRestError as e:
print("Error fetching snapshot details: %s" % e)
On a side note, your code could be made a little more efficient. Right now, you are calling get_collection() and then for each result you are calling get() on it inside the loop to fetch additional fields. You could make this more efficient by passing the field list to get_collection() and then you don't need the get() inside. Here is the same code refactored:
from netapp_ontap import HostConnection, NetAppRestError
from netapp_ontap.resources import Volume, Snapshot
with HostConnection(hostname, username, password, verify=False):
for volx in Volume.get_collection(fields="uuid,svm,name"):
vservername = volx.svm.name
print(volx.svm.name)
for snapx in Snapshot.get_collection(volx.uuid, fields="volume,snapmirror_label,create_time,name")
print(snapx.name)
