hi, introduce my current environment： FAS3220 , VERSION: NetApp Release 8.1.3P3 7-Mode. the problem: the prior environment, we created a cifs share with two windows 2008 R2 active directory. according to the customer request, I was created two new windows 2008 R2 host. and adding to active directory but the from the netapp GUI interface , for domain controler display , i can see three active directory. it's not four active directroy from the command line, check the domain info: but after about ten minutes , will be show the following picture, at the domain directory item, all of the active directory is disappear. during the cifs service is unavailable also. so what's wrong for the NETAPP storage ?

We are currently playing with ideas for how we want to do backups going forward. Currently we have a server that runs Netvault that does NDMP from the NetApp to tape. However reading the Ontap docs leads me to believe that it is possible for the NetApp to talk directly to a library, no server needed. I'm interested in that, but can't seem to find any information on it. So what I'm wondering is if this is something that can be done or not with our setup? We have a FAS2620 that hooks up to to a 212C disk shelf. All 4 SAS ports on the host are used to do the redundant hookup to the shelf. So would we be able to hook a tape drive up to the shelf and just have it as part of the SAS loop? If so, is there a way to find out what tape libraries are supported? Finally, is this a terrible idea? 🙂

Dear Community,
since we have updated some of our systems (FAS82xx, AFF A300) to Ontap 9.3P7,
we see the following Errors in Messages for our (UTA2) 10GBit LAN-Ports, which have not been here before the update.
10/16/2018 11:04:14 <Filer>-<node> ALERT vifmgr.cluscheck.crcerrors: Port e0g on node <Filer>-<Node> is reporting a high number of observed hardware errors, possibly CRC errors.

From my feeling it looks like a BUG in Data Ontap 9.3P7 (Error in their Portstats, ...), as we dont find any matching Errors in our Network infrastructure. Also no impact seen to the systems.
I already opened a support Case, but uptonow they cannot match this to an existing BUG, as 9.3P7 should have fixed all issues regarding this problem.
So timeconsuming debugging on customer site must be done to find the root-cause 😞
So the Question to the community: Anybody seen this Errors on Ontap 9.3P7?
Best Regards,
Klaus
