Hi All,
We extensively use NetApp API calls to monitor 7Mode filers, and took the same approach for cDOT monitoring.
Here is a very unpleasant discovery:
1. Take one node (or more nodes) *offline*, eg power it off for maintenance. 2. Try to run *any* API call against cluster interface and get the following error:
OUTPUT: <results reason="RPC: Port mapper failure - RPC: Timed out" status="failed" errno="13001"></results>
It effectively makes your cluster wide monitoring useless.
Any ideas? Is it a feature or a bug?
Cheers, Vladimir
