for some time I am trying to solve issue regarding API call for LUN capacity list from Netapp Harvest to Active IQ.
At least once a day LUN capacity Harvest call towards AIQ ends with error and it stays broken untill workaround is applied.
Call ends with general 13001 error (confirmed by Netapp engineer).
Zexplorer "lun-iter" calls are ending with 13001 error as well. During this time also "dfm lun list" is not working with "internal error" message.
If I try to lower "max-records" some iterations will work, until it hits error 13001. If I look for "next-tag" that does not work, everyday it is different "tag". Broken "tag" remains the same untill workarround is applied".
When I tried to skip broken "tag" usually some other one was not working as well.
Every other api call like "aggr-iter" or "volume-iter" are working all the time.
Only ONTApi calls are affected.
RestAPI and "um lun list" are working all the time.
Error 13001 definitely is a generic communication issue as you might have suspected, especially when there is an API communication issue between Harvest and SDK. I didn't see which version of Harvest you are running. Some of these communication issues have been resolved in Harvest 1.6.1.
