Bug Description
ISO: ubuntu-
System environment: two ports connected to the network. The first port connects with IPv4 DHCP server. The second port connects with IPv4 and IPv6 DHCP server.
After installation completed through the 2nd NIC port, the system failed to boot via the remote IPv6 iSCSI disk. The system hangs on the "iscsistart: cannot make a connection to 0.0.7.209:0 (-1,101)". There are possible problems.
The iscsistart uses the wrong port, the 1st port, to connect the iSCSI service. After adding the parameter ip=:::::eno1:off, the iscsistart uses the 2nd port to connect but still with IPv4 address. Adding the other parameters, ip=:::::eno2:off ip6=eno2, the iscsistart gets the IP, 0.0.0.0 on eno2 to connect the service. The eno2 gets the IPv6 address after the iscsistart connection.
The iscsistart also can't recognize the IPv6 address. The log shows "Logging into iqn.2100-
