This section explains the procedure for configuring the shutdown facility with the shutdown configuration wizard.
The configuration procedure for the shutdown facility varies depending on the machine type. Check the machine type of hardware and set an appropriate shutdown agent.
The following table shows the shutdown agent necessary by machine type.
Server machine type name | RCI | XSCF | ALOM | ILOM | |||||||
|---|---|---|---|---|---|---|---|---|---|---|---|
Panic | Reset | Panic | Reset | Break | Break | Panic | Reset | ||||
SPARC Enter | M3000 | Japan | Fujitsu | Y | Y | Y | Y | Y | - | - | - |
Other than Fujitsu | - | - | Y | Y | Y | - | - | - | |||
Other than Japan | - | - | Y | Y | Y | - | - | - | |||

SPARC | T3 series | - | - | - | - | - | - | Y | Y | ||
(*1) When using ILOM Reset, you need firmware for SPARC Enterprise server (System Firmware 7.1.6.d or later).
Note
When you are operating the shutdown facility by using one of the following shutdown agents, do not use the console.
XSCF Panic
XSCF Reset
XSCF Break
ILOM Panic
ILOM Reset
If you cannot avoid using the console, stop the shutdown facility of all nodes beforehand. After using the console, cut the connection with the console, start the shutdown facility of all nodes, and then check that the status is normal. For details on stop, start, and the state confirmation of the shutdown facility, see the manual page describing sdtool(1M).
In the /etc/inet/hosts file, you must describe IP addresses and host names of the administrative LAN used by the shutdown facility for all nodes. Check that IP addresses and host names of all nodes are described.
When you set up asynchronous RCI monitoring, you must specify the timeout interval (kernel parameter) in /etc/system for monitoring via SCF/RCI. For kernel parameter settings, see the section "A.5.1 CF Configuration."
If a node's AC power supply is suddenly disconnected during operation of the cluster system, the PRIMECLUSTER, after putting the node for which the power supply was cut into LEFTCLUSTER status, may disconnect the console. In this instance, after confirming that the node's power supply is in fact disconnected, cancel the LEFTCLUSTER status using the cftool -k command. Afterwards, reconnect the console and switch on the power supply to the node.
If the SCF/RCI is malfunctioning or if there is the detection of a hardware error such as the RCI cable being disconnected or detection of redundant RCI address settings, it will take a maximum of 10 minutes (from the time that the error is detected or the shutdown facility is started up) until those statuses are reflected to the sdtool -s display or shutdown facility status display screen.
After setting the shutdown agent, conduct the cluster node forced stop test to check that the cluster nodes have undergone a forced stop correctly. For details on the cluster node forced stop test, see "1.4 Test."
To make the administrative LAN, used in the shutdown facility, redundant by GLS, use the physical IP address takeover function of NIC switching mode.
See
For details on the shutdown facility and the asynchronous monitoring function, refer to the following manuals:
"3.3.1.7 PRIMECLUSTER SF" in the "PRIMECLUSTER Concepts Guide".
"8. Shutdown Facility" in "PRIMECLUSTER Cluster Foundation (CF) Configuration and Administration Guide".
In SPARC Enterprise M3000, M4000, M5000, M8000, and M9000, XSCF is used. The connection method to XSCF as the shutdown facility can be selected from SSH or the telnet.
Default connection is SSH.
Please confirm the following settings concerning XSCF before setting the shutdown facility.
Commonness
The log in user account must be made excluding root for the shutdown facility, and the platadm authority must be given.
At the SSH connection
In XSCF, SSH must be effective in connected permission protocol type from the outside.
User inquiries of the first SSH connection (such as generation of the RSA key) must be completed by connecting to XSCF from all the cluster nodes via SSH using the log in user account for the shutdown facility.
At the telnet connection
In XSCF, telnet must be effective in connected permission protocol type from the outside.
Note
When the connection to XSCF is a serial port connection alone, it is not supported in the shutdown facility. Please use XSCF-LAN.
Moreover, record the following information on XSCF.
XSCF IP address or an XSCF host name registered in the "/etc/inet/hosts" file of the node
Log in user account and password for shutdown facility in XSCF
*1) When the network routing is set, IP address of XSCF need not be the same to management LAN segment of the cluster node.
See
For information on how to configure and confirm XSCF, see the "XSCF User's Guide".
The required shutdown agent varies depending on the hardware machine type.

Even if a cluster partition occurs due to a failure in the cluster interconnect, all the nodes will still be able to access the user resources. For details on the cluster partition, see "2.2.2.1 Protecting data integrity" in the "PRIMECLUSTER Concepts Guide".
To guarantee the consistency of the data constituting user resources, you have to determine the node groups to survive and those that are to be forcibly stopped.
The weight assigned to each node group is referred to as a "Survival priority" under PRIMECLUSTER.
The greater the weight of the node, the higher the survival priority. Conversely, the less the weight of the node, the lower the survival priority. If multiple node groups have the same survival priority, the node group that includes a node with the name that is first in alphabetical order will survive.
Survival priority can be found in the following calculation:
Survival priority = SF node weight + ShutdownPriority of userApplication
Weight of node. Default value = 1. Set this value while configuring the shutdown facility.
Set this attribute when userApplication is created. For details on how to change the settings, see "8.1.2 Changing the Operation Attributes of a Cluster Application".
See
For details on the ShutdownPriority attribute of userApplication, see "6.7.5 Attributes".
The typical scenarios that are implemented are shown below:
Set the weight of all nodes to 1 (default).
Set the attribute of ShutdownPriority of all user applications to 0 (default).
Set the "weight" of the node to survive to a value more than double the total weight of the other nodes.
Set the ShutdownPriority attribute of all user applications to 0 (default).
In the following example, node1 is to survive:
Set the "weight" of all nodes to 1 (default).
Set the ShutdownPriority attribute of the user application whose operation is to continue to a value more than double the total of the ShutdownPriority attributes of the other user applications and the weights of all nodes.
In the following example, the node for which app1 is operating is to survive:
