snapshot-get-iter unable to get info of all volumes

[BALAGUDURU]

Hi,

I am using snapshot-get-iter to report all volumes and it's snapshots details. For that I am using max-records ad 500 and tag as none. When I ran in ZEDI with no query, just plane snapshot-get-iter, I am getting an error when it is looking for snapshots of offlined volumes. I changed the max-records to 1000 then it pulled more volumes which it couldn't when it was 500 but failing at the offlined volumes. Similar error message for both the situations.

Error: 

/next-tag>
       <num-records>500</num-records>
               <volume-errors>
               <volume-error>
                         <errno>13023</errno>
                         <name>test_volume</name>
                         <reason>Unable to get information for Snapshot copies of volume &quot;test_volume&quot; on Vserver &quot;test_vservert&quot;. Reason: Volume not online.</reason>
                          <vserver>test_vserver</vserver>
                </volume-error>
                </volume-errors>
        </results>
</netapp>

I am using Python to make these api calls. Please let me know if there is something I am missing or an alternate to getting the snapshot info info of all volumes in 1/2 calls. I know we can query on per volume basis by specifying the volume name in snapshot-list-info. But it would take a million calls for million volumes and forever for the script to complete.
