Notes on the Remote Power Management Function (RCIL)


Notes on the Remote Power Management Function (RCIL)
  1. To use the remote power management function on XCP 2290 onwards, execute the setpacketfilters -c ipmi_port command to set the IPMI service.
    The SPARC M10 IPMI service is used only with the remote power management function.
    From XCP 2290 onwards, the IPMI service is disabled by default. To use the remote power management function, enable the IPMI service.
    For XCP 2280 or earlier, the IPMI service cannot be disabled. It is always enabled. If the firmware is updated from XCP 2280 or earlier to XCP 2290 or later, the IPMI service will remain enabled. Therefore, if the remote power management function is not used, disable the IPMI service. If remote power management has been used, the function will still be available.
    The IPMI service can be set by executing the setpacketfilters -c ipmi_port command. For details on the setpacketfilters(8) command, see the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 XSCF Reference Manual.
  2. Do not register the same node with multiple remote power management groups. If remote power management is performed by registering a single node with multiple remote power management groups, the operation may not be as intended.
    With the setremotepwrmgmt(8) command, you cannot confirm whether a single node is registered with multiple remote power management groups. When creating or modifying management information files of remote power management groups, take care not to cause overlaps.
  3. Do not register an I/O node with multiple power control groups. If the same I/O node is set with multiple remote power management groups, and both of the conditions below are satisfied, the I/O node is turned on and off alternately.
    - setremotepwrmgmt -c enable is executed, and the remote power management function is enabled.

    - There is a power control group in which one or more host nodes are on, and there is a power control group in which all the host nodes are off.

    If you accidentally register an I/O node with multiple power control groups, use setremotepwrmgmt -c disable to disable remote power management first, and then use clearremotepwrmgmt to delete the power control group setting. After deletion, create a management information file of a remote power management group so that the I/O node is not registered with multiple groups, and then use setremotepwrmgmt -c config to register it again.
  4. If XCP 2080 or earlier is used together with a single SPARC M10 system that is connected to an external I/O device, do not use the remote power management function. The external I/O device may be erroneously powered off when the XSCF is reset.
  5. For a management file to set the remote power management function, use CR and LF, or LF as linefeed code.
  6. For a management file to set the remote power management function, you need to specify the MAC address in spite of the node type. Otherwise, the following error occurs when you execute the setremotepwrmgmt(8) command.
  1. [Example]
XSCF> setremotepwrmgmt -c config -u guest ftp://xx.xx.xx.xx/rpmgroup.csv

  1. You need to set the MAC address regardless of the node type of the I/O node, master host node, host node, or remote power supply control unit. This is required even though the MAC addresses of some nodes are not set and left "blank" as described in "Chapter 3  Examples of Remote Power Management Configuration" in the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 RCIL User Guide.
