Planning The Clustered Enterprise Server Interfaces - IBM RS/6000 SP Handbook

If you plan to attach an existing 7017 or 7026 server to your system, you must
place an SP LAN Ethernet adapter in the slot en0 position inside the server. Due
to the fact that the Ethernet adapter in this slot must be configured for PSSP
communications, any non-supported Ethernet adapter that is in the en0 slot must
be removed. Additionally, if the Ethernet adapter in slot en0 is a supported
Ethernet adapter, the adapter must be de-configured and then reconfigured as
an SP-LAN Ethernet adapter.
For a complete listing of currently supported SP system PCI adapters, see
Chapter 8, "PCI communication adapters" on page 227. With the exception of the
RS/6000 SP System Attachment adapter (which is supported), if an adapter
does not appear in the list, it is not supported for the CES. If you plan to use an
existing Enterprise Server and any installed adapters do not appear in this list,
they must be removed before it can be attached to the Clustered Enterprise
Server.
Clustered Enterprise Server software requirements
The Clustered Enterprise Servers M/T 7017 require the following software levels:
PSSP 3.2 with APAR IY13026 (or later)
AIX 4.3.3 with ML-06 (or later)
The Clustered Enterprise Servers M/T 7026 require the following software levels:
PSSP 3.2 with APAR IY16350 (or later)
AIX 4.3.3 with ML-08 (or later)
Note:
1. AIX 5L operating system is not supported on Clustered Enterprise Server
environment.
2. If you plan to attach an existing enterprise server in the CES system, and
that server is connected to an IPV6 network, you must remove the server
from that network before including it in the CES system (some PSSP
components tolerate IPV6 aliases for the IPV4 network but not with DCE,
HACMP, HACWS, or an SP Switch).
3. Each Clustered Enterprise Server requires its own (chargeable) PSSP
license.

3.5.2 Planning the Clustered Enterprise Server interfaces

The Clustered Enterprise Server requires different connections with your CES
system.
