vol move throughput throttle
by Mike Thompson 28 Feb '19

28 Feb '19

did a throttle to volume move throughput throttle ever make it into ontap 9? I see there was some discussion about this on the list a few years back, with the consensus that it was a known desire to have a throttle in there, and someday maybe it would make it in. I see there is a throttle on the number of concurrent moves, but don't see anything specific to throughput rate.

environmental control?
by Mark Flint 11 Feb '19

Hi list, does anyone know if there’s an official shutdown temp for a 3270 FAS in HA 7-mode? I can see the operating temperature list, and have wandered through the environment settings, and first impression is that it’s a function of inflow temp being too high, and possibly two other subsystem reporting too high, for environmental shutdown to occur, but that’s just guessing :) I’dreally like a link to a doc that says “w3270’s shutdown at 54 degrees celsius” or similar…….

Yep it is, I just discovered it... But *it's not mentioned in the Release Notes, *despite being something many people have asked for for a long time... I''ll fire up my 9.4 sim and will check Diag Mode. It's probably not in Advanced Mode, since it's not mentioned in the 9.4 Man Pages (and they DO contain Advanced Mode stuff...)

Hide Snapshots from NFS clients
by Sebastian Goetze 04 Feb '19

Hi All, I'm teaching a SMB/NFS combo at the moment, and the question again came up, how to hide ".snapshot" from NFS users/scripts (like in the 7-Mode days). In the Man Pages I found *[ -v3-hide-snapshot {enabled|disabled} ] - Hide Snapshot Directory under NFSv3 Mount Point* This optional parameter specifies whether to hide the .snapshot directory while listing under NFSv3 mount points. However an explicit access to the .snapshot directory will still be allowed even though the option is enabled. The default setting is disabled at the time of creation. (I checked, it's not in 9.4) Greetings from Munich Sebastian NAI (NetApp Instructor) _________________________________________________ Jeremy asked Feb 5, 2016: In 7-mode we are able to make snapshots accessible, but invisible to NFSv3 clients. In this mode there is a .snapshot directory, but if you ‘ls’ that directory it appears empty. However, if you ls .snapshot/hourly.0 say then you can see that the snapshot is in fact there. We now have an 8.3.1 CDOT filer and have not been able to work out how to reproduce the behaviour. The snapshots are either accessible and visible (which causes problems for programs which walk the tree) or not accessible at all.…
