esxi version - 6.7 U3
truenas version - FreeNAS-11.2-U8
using software iscsi
attaching esxtop details , alerts screenshot
Networking
esxi host>to>ip switch>>freenas using 10g network
MTU set on esxi/freenas - 1500
on switch its set to 9000.
Can anyone help me to figure out what is happening and how to stop the alerts?
Below was tried already->
1. changed iscsi timeout = 0 on freenas
2. esxi upgrade
3. esxi reboot
4.disable/enable sw iscsi adapter
5.rescan
6.target delete and recreate on freenas
Thanks!
Anything to do with you having installed updates for a security advisory, or not?
the only update i did was applied release patch for esxi 6.7 u3 for this issue which did not help. Anything else that I can tune on freenas or esxi to get rid of these alerts?
