FAS and V-Series Storage Systems Discussions
i just upgraded to Ontap 9.5P4 and got the same issus:
: vifmgr.cluscheck.crcerrors: Port e0b on node is reporting a high number of observed hardware errors, possibly CRC errors.
opened a support case and will update.
Hello @miller ,thanks for your message. We already have a support case opened, in our environment the presence of CRC errors seems the cause of link flapping on multimode_lacp interface groups.net.ifgrp.lacp.link.inactive: ifgrp a0a, port e0c has transitioned to an inactive state. The interface group is in a degraded state.This happens also when almost there's no traffic (our 9.5P3 systems are not yet in production) and not happens with high traffic systems with 9.1 , where the number of CRC is higher...
since I am working on the support case for @LORENZO_CONTI would you please be able to share your support case with me?
A PM will be fine as well!
Thanks in advance.
We had same issue our customer and they changed jumbo frames on switch and netapp after that this issue was fixed.
(FAS9000 , Ontap9.5P5)
Hi @buraksenturk , could you please explain better? What do you mean with "changed jumbo frames" exactly?Thank you
port set to switches 9000 and also port set netapp 9000.
thats example from customer;

We have same Error since 5 Month, NetApp does not find a solution.The port we have problems with, is e0M (Management).e0M can not be higher than MTU 1500, Switch is configured too on MTU 1500 and with 1000 Mbps.
PKoza can you post your ifstat output for that port?
Here it is attached.
The long frames are non-zero.
