Looking at the sample code it always seems to just check na_results_status(out) for not NA_OK as an indication of error. In most cases it we got NA_OK it says we're good.
I'm trying to use snapshot-multicreate and it seems I can get na_results_status(out) as NA_OK but the call didn't work. What SHOULD I check...
Options seem to be to see if there was any <volume-error> tag or a <status>false</status>. I'm still surprised that I didn't get a non OK result from na_results_status(out)
This is ONTAP 8.2 cluster mode. The output buffer looks like:
<?xml version='1.0' encoding='UTF-8' ?>
<netapp version='1.20' xmlns='http://www.netapp.com/filer/admin'>
<results status='passed'>
<status>false</status>
<volume-errors>
<volume-error>
<errno>13025</errno>
<name>vol_mt_14</name>
<reason>Snapshot operation failed: No space left on device.</reason>
</volume-error>
</volume-errors>
<volume-is-snapcreated-list>
<volume-is-snapcreated>
<is-snapcreated>false</is-snapcreated>
<name>vol_mt_00</name>
</volume-is-snapcreated>
<volume-is-snapcreated>
<is-snapcreated>false</is-snapcreated>
<name>vol_mt_01</name>
</volume-is-snapcreated>
<volume-is-snapcreated>
<is-snapcreated>false</is-snapcreated>
<name>vol_mt_02</name>
</volume-is-snapcreated>
