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.

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?

Hi everyone, I have the strangest behaviour on a V-series appliance. First some introduction to my infrastructure setup is in order. I have an old SUSE 9 server which is a client for NFS shares on a FAS2020 appliance. This appliance is being retired and the shares are moved to a new V-series Netapp appliance. The majority of the content of the shares I have copied via SMB and a third party server onto the new appliance. I have then mounted the new NFS shares onto the SUSE server and reading and writing to the mounts is working with no issues ... except when I want to copy certain XML files that have been generated by our ERP system. Strange thing is most of the XML files I can copy with no issue, only copying certain XML files hangs. What is worse the whole mount then hangs too i.e. the whole ERP/finance system hangs. The server itself remains fully manageable but disk IO operations hang. I can recover the system by forcibly unmounting the NFS share but the copy process does not finish/ finishes with errors. I have blamed this behaviour on a firewall but I was proven an idiot by the network guys as the issue persists even when the server and the appliance are directly connected (no firewall inbetween). I even did a network sniff on the issue (see attached picture) and it shows that the NETAPP is refusing to service the write request, which just ends in retransmissions for eternity... thus a hang. The strange thing is ... the whole process works and has worked for a decade now on the old FAS2020 appliance. Both appliances are being accessed via NFS v3... so no difference there. I would be grateful for any help at this point! Oh and I have forgotten to mention this experiment that I performed. I have tried zipping the XML files and then copying them onto the NFS share ... works with no problem. Unzipping the files straight to the new destination ... hangs! I guess the V-series appliance just hates the content of my XML files.

Hello, I have a FAS2240 with release 8.2.4P4 7-Mode with the following RAID DP configuration 1 disk parity 1 disk dparity 8 disks data 2 disks broken (0a.00.2 and 0a.00.4) => No more spare disks I swapped the broken disks with new ones coming from another unused FAS2240 and ran the commands : # disk assign 0a.00.4 -s unowned –f # disk assign 0a.00.4 # Thu Feb 25 13:51:43 CET [NAS-cluster9-CTRL1:raid.assim.rg.missingChild:error]: Aggregate foreign:aggr0, rgobj_verify: RAID object 0 has only 1 valid children, expected 10.

Use the 'aggr online' command to bring it online.

That's not the case. What is wrong in that procedure? Thanks a lot for your help.
