14.6.2 Understanding Forms of Connection for Remote Power Management


14.6.2 Understanding Forms of Connection for Remote Power Management
Connect through a LAN the host nodes, subnodes, and I/O nodes that support the remote power management function for the SPARC M12/M10.

The connection specifications are as follows.
Table 14-13  Power Supply Control Connection Specifications
Item Description
Forms of connection LAN connection
The connection takes either of the following forms:
- Using XSCF-LAN#0

- Using XSCF-LAN#0 and XSCF-LAN#1
Transmission rate 100 Mbps or more
Internet protocol IPv4
DHCP Not supported
If the remote power management function for the SPARC M12/M10 is used, you must set a fixed IP address for a connection target.
Connection protocol IPMI(*1) over LAN
(Intelligent Platform Management Interface)
*1 The supported IPMI version is IPMI 2.0.
In a SPARC M12/M10, IPMI can be used only internally by the remote power management function. IPMI cannot be used by ipmitool or any function other than the remote power management function of the SPARC M12/M10.
Standard Connection for Remote Power Management
Connect through an identical LAN the host nodes, subnodes, and I/O nodes that are equipped with a controller that supports the remote power management function for the SPARC M12/M10.

Connection in the Case of Duplexed Controllers
If the controllers of a host node are duplexed, each controller can be connected to an identical LAN. Operation of the remote power management is performed from the master XSCF.

Note - We recommend setting a takeover IP address on the I/O nodes that can set a takeover IP address between controllers. In this case, set controller 0 and controller 1 to the same IP address in the management file for configuring the remote power management group.
For specific settings, see "3.1.1  System That is Configured with a Host Node and an I/O Node" in the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 RCIL User Guide.
Connection in the Case of Duplexed Paths
If the following conditions are met, the connection paths for remote power management can be duplexed.
  1. When two LAN cards can be installed on each controller of all nodes
  2. When two LAN cards can be installed on a controller of a host node, and an I/O node has either of the following configurations
    - Controllers of an I/O node are duplexed

    - Two LAN cards can be installed on a controller of an I/O node
