Hi,
sorry for the delay, I reinstalled everything, configured the networks,
attached the iSCSI storage with 2 interfaces and finally created the
iSCSI-bond:

The host keeps toggling all storage domains on and off as soon as there
is an iSCSI bond configured.
Thank you for your patience.

I don't think it's necessary.
Please provide the host's routing table and interfaces list ('ip a' or
ifconfing) while it's configured with the bond.
Thanks

Yes, I made sure it is not part of the bond.
It does seem to have a conflict between default and enp9s0f0/
enp9s0f1.
Try to put the host in maintenance and then delete the iscsi
nodes using
'iscsiadm -m node -o delete'. Then activate the host.
I tried that, I managed to get the iSCSI interface clean, no
"default" anymore. But that didn't solve the problem of the host
becoming "inactive". Not even the NFS domains would come up.
As soon as I remove the iSCSI-bond, the host becomes responsive
again and I can activate all storage domains. Removing the bond also
brings the duplicated "Iface Name" back (but this time causes no
problems).
...
I wonder if there is a basic misunderstanding on my side: wouldn't
it be necessary that all targets are reachable from all interfaces
that are configured into the bond to make it work?
But this would either mean two interfaces in the same network or
routing between the iSCSI networks.
Thanks,
Uwe
