1.4. Plan for necessary IP addresses
You should plan to assign IP addresses to the following components for a minimum IBM i on
blade configuration. All the addresses below are typically configured on the same subnet.
•
AMM
(this IP address is already assigned on an existing BladeCenter)
o
The AMM IP address is a physical LAN IP address. It will be used to remotely
manage the BladeCenter and blade servers
•
Ethernet I/O module
(this IP address is already assigned on an existing BladeCenter)
o
This IP address will be used to connect the Ethernet I/O module to the physical
LAN, allowing any blades in the BladeCenter access to the LAN
•
VIOS/IVM
o
An IP address on the external LAN that will be used to connect to both IVM and
the VIOS command line
•
IBM i LAN console
o
An IP address on the external LAN that will be used to provide 5250 console
access to IBM i via a PC with the System i Access for Windows software. The
address will be assigned to the IBM i partition when the LAN console connection
is first established.
Note that this IP address is different from the VIOS IP
address and the IP address later used for IBM i production TCP/IP traffic.
•
IBM i production interface
o
An IP address on the external LAN that will be used for IBM i production network
traffic. This address will be configured after IBM i is installed using LAN console.
It is recommended that the IBM i LAN console and production network interface
use two separate Virtual Ethernet adapters in the IBM i partition
•
PC for LAN console and IVM browser access
o
When the IBM i LAN console connection is first established, the console PC
must
be on the same subnet
as the IBM i partition. Once the console is established,
this restriction is removed
•
SAS I/O module 1
o
An IP address on the external LAN that will be used to connect to the SAS I/O
module. This IP address is required in order to manage the SAS module
configuration and assign SAS drives in the chassis to blades.
•
SAS I/O module 2
o
An IP address on the external LAN that will be used to connect to the SAS I/O
module. This IP address is required in order to manage the SAS module
configuration and assign SAS drives in the chassis to blades. A second SAS I/O
module is optional in the BladeCenter S.
•
SAS RAID controller module 1
o
This applies only to BladeCenter S.
An IP address on the external LAN that
will be used to communicate specifically with the RAID subsystem in the module.
When a pair of these I/O modules is used, an IP address is also required to be
assigned to the RAID subsystem in addition to assigning an IP address to the
SAS switch component of the module.
•
SAS RAID controller module 2
o
This applies only to BladeCenter S.
An IP address on the external LAN that
will be used to communicate specifically with the RAID subsystem in the module.
Two such modules must always be used; therefore, this IP address is required if
the RAID SAS modules are installed.
•
Fibre Channel switch modules
o
This applies only to BladeCenter H.
An IP address on the external LAN that
will be used to communicate with a Fibre Channel switch module through the
AMM. This IP address is required for switch configuration and firmware updates.
