Chapter 4. Making the transition to the IBM Systems Director Management Console 73
4.4.1 SDMC as the DHCP server
Perform the following steps to perform a transition of managed systems in the
private network with the SDMC as the DHCP server:
1. Disconnect the HMC from the private network.
2. Connect the SDMC to the private network.
3. Configure the network interface of the SDMC with the correct DHCP range.
The IP addresses of the managed systems might change after the renewal of
the DHCP leases from the SDMC. SDMC then auto-discovers the managed
systems.
4. Request access to the managed systems.
After successful authentication, you can start managing the systems using the
tasks available on the context menu of the system. The Virtual Servers hosted by
the managed system are retrieved automatically.
4.4.2 HMC as the DHCP server
When the existing HMCs are currently the DHCP servers and SDMC will replace
one HMC as the DHCP server on the same DHCP range used by the HMC, you
have two methods of transitioning systems.
For the first method, perform the following steps to perform a transition of
managed systems:
1. Connect the SDMC to the HMC2 port of the managed system. Leave the
other HMC connected to the HMC1 port of the managed system.
Now, the HMC is the DHCP server for the managed systems on the network
to which the HMC1 port is connected. The SDMC will be the DHCP server for
those systems on the network to which the HMC2 port is connected, replacing
the other HMC that used to perform this function..
2. Configure the network interface with the same DHCP range as the HMC that
used to be attached to the HMC2 of the managed system.
The IP addresses of the managed systems might change after renewal of the
DHCP leases from the SDMC. SDMC then auto-discovers the managed
systems.
3. Request access to the managed systems.
After successful authentication, you can start managing the systems using the
tasks available on the context menu of the system. The Virtual Servers hosted by
the managed system are retrieved automatically.
