If you want to set up an ASM interconnect network and have not already done so,
continue with “Using the ASM interconnect network”. If you do not want to set up an
ASM interconnect network, Remote Supervisor Adapter configuration is now
complete. To start managing the server remotely, see the Remote Supervisor Adapter
User’s Guide on the IBM Documentation CD.
Using the ASM interconnect network
This section explains how to configure and connect the server to function within an
ASM interconnect network.
The ASM interconnect network can include as many as 12 individual ASM
connections in a single bus. These connections can include Remote Supervisor
Adapters, ASM processors, and ASM PCI Adapters. When the clients and servers
are connected, they use the ASM interconnect network to share ASM resources,
information, and alerts among multiple servers, without having to add additional
communications hardware or network interface adapters.
An ASM interconnect network provides two levels of functionality. First, the ASM
interconnect network enables you to configure settings and to control the servers
where other Remote Supervisor Adapters, ASM processors, and ASM PCI Adapters
on the network reside. Second, the ASM interconnect network enables other
interconnect network devices to use the resources (Ethernet or modem) of other
Remote Supervisor Adapters, ASM processors, and ASM PCI Adapters in the ASM
interconnect network for sending alerts. This interconnect network is used when
Remote Supervisor Adapters, ASM processors, or ASM PCI Adapters cannot send an
alert and must forward the information to another one of these devices to send the
alert.
Planning and cabling the interconnect
network:
To support the most recent ASM features, a Remote Supervisor Adapter
must be the main gateway interconnect to the ASM interconnect bus if the bus also
includes servers with ASM PCI adapters or ASM processors. The Remote Supervisor
Adapter forwards the ASM information generated by the servers attached to the ASM
interconnect bus to other servers on the Ethernet network. The connected ASM
processors and ASM PCI Adapters are managed through the new user interface and
Web browser access of the Remote Supervisor Adapter.
Note: To ensure the stability of the system, you must have the most current level of
firmware installed on the Remote Supervisor Adapter that is the main
interconnect gateway for the ASM interconnect network. The most current
level of firmware is available on the World Wide Web at
http://www.ibm.com/pc/support. For more information on updating firmware,
see the Remote Supervisor Adapter User’s Guide for the xSeries 440 on the
Documentation CD.
You must connect an ASM Interconnect module to the Remote Supervisor Adapter
and to each xSeries 440 server that you connect to the ASM interconnect network
bus.
Attention: To avoid damage to the Ethernet connector on the Remote Supervisor
Adapter, do not plug the ASM Interconnect module into the Remote Supervisor
Adapter Ethernet port.
