I am trying to install SLES 12 SP3 in an LPAR.
The computer is a z13s and the LPAR has 32GB assigned.
I burned the ISO file to a DVD, put the DVD in the HMC, and IPL'd for the DVD.

The IPL started but seems to have stopped at a certain point, before I could give it network devices or DASD devices.

The last message I see is:
8021q: 802.1Q VLAN Support v1.8

Has anyone had this problem?
How can I fix it.
