Volume attributes sometimes initialized and sometimes not

alisahaw — Thu, 05 Sep 2019 20:29:16 GMT

Hello, sorry if this is in the wrong discussion section. I have an issue with some of my read-only volumes sometimes not having space attributes.

for cluster in cluster_list: server = netapp.netapp_login(cluster) request = server.invoke('aggr-get-iter', 'max-records', 10000).child_get('attributes-list') if request is None: print "No aggregate attributes were found for cluster:", cluster continue request = request.children_get() for a in request: aggr_name = a.child_get_string('aggregate-name') space_attrs = a.child_get('aggr-space-attributes') if space_attrs is None: print "No space attributes were found for:", aggr_name, cluster continue size = space_attrs.child_get_string('size-total') used = space_attrs.child_get_string('size-used')

The error messages look like this:

No space attributes for: edadisk002_ro_6a torcfs01 No space attributes for: edagroup_ro_5b torcfs01 No space attributes for: edalicense_ro_5b torcfs01

And they aren't consistent. This script runs every five minutes but I'll get this notification for different volume(s) each time and only a couple times a day (or none at all). Any idea why this could be happening?

Please provide the below command output from the Command Line on the cluster from SSH session over putty etc.,

To see the OS version, aggr details and number and limits of ZAPI

::*> version

::*> aggr show-view

::*> ontapi limits show

Just a note, this issue has been seen on almost all clusters in our environment.
