IPU-POD128 build and test guide
sudo scp /etc/dhcp/dhcpd.d/vlan-11.conf ipuuser@pod7:/etc/dhcp/dhcpd.d/lrack2
Step 3: Edit DHCP config files for lrack1
You need to edit the following management network DHCP files on lrack1:
•
/etc/dhcp/dhcpd.d/lrack1/vlan-13.conf
•
/etc/dhcp/dhcpd.d/lrack2/vlan-13.conf
Step 4: netplan setup
There are examples of the netplan files that you are required to edit in
Section 8.7, /etc/netplan files
. There are
also descriptions of how to edit them. You need to carry out the netplan setup changes in this step in the order
they are given (4a - 4d).
4a) BMC management
Create a netplan setup for the BMC management subnet interface of the lrack1 management server using the
new management network address 10.1.7.150.
4b) IPU-Gateway management
Create a netplan setup for the IPU-Gateway management subnet interface of the lrack1 management server using
the new management network address 10.2.7.150.
4c) Lrack1 RNIC interface
Create a netplan setup for the lrack1 management server RNIC interface using the new management network
address 10.5.7.150.
4d) lrack2 RNIC interface
Note:
This part of the step is only required if there is no spine switch enabling full RDMA connectivity between
the two IPU-POD
64
racks.
Create a netplan setup for the lrack2 management server RNIC interface using the new management network
address 10.5.8.150.
Step 5: Update vlan-11.conf files
1) Modify
/etc/dhcp/dhcpd.d/lrack1/vlan-11.conf
on lrack1 using the new network addresses. For example:
#
server RNIC addresses also
set
by the
150
server’s DHCP server
#
ONLY:
if
rack has
4
servers
#
lr7-server1mx is setup using netplan to
10
.5.7.150
host lr7-server2mx { hardware ethernet 1c:36:da:4b:ea:ef; fixed-address 10.5.7.151; }
host lr7-Server3mx { hardware ethernet 0c:44:a1:20:7c:83; fixed-address 10.5.7.152; }
host lr7-Server4mx { hardware ethernet 0c:44:a1:20:80:a3; fixed-address 10.5.7.153; }
Once you have edited this file then you follow 2) or 3) depending on whether you have spine switches or not.
Either: 2)
Modify
/etc/dhcp/dhcpd.d/lrack2/vlan-11.conf
on lrack1 using the new network addresses.
Note:
This is only required if you have spine switches enabling full RDMA connectivity between the two
IPU-POD
64
racks.
