PRIMECLUSTER Installation and Administration Guide 4.1 (for Solaris(TM) Operating System)

6.6.1.5.2 Setup Method

This section describes how to create takeover network resources.

[Flow of takeover network resource creation]

For information on the above operations up to "Select SysNode," see "Creating Cmdline Resources." This section describes the operations starting from "Select takeover network."

Selecting a takeover network

Select the takeover network type.

[Network type selection]

IP address takeover

Select this item to enable IP address takeover.

Node name takeover + IP address takeover

Select this item to enable node name takeover and IP address takeover.
If node name takeover has already been set, you are not allowed to set twice.

In this version, "MAC address takeover + IP address takeover" and "MAC address takeover + node name takeover + IP address takeover" cannot be selected.

To set MAC address takeover, perform the operations described in "Prerequisites," and then select "IP address takeover" or "node name takeover + IP address takeover" and create the takeover network resources.

You can configure a network interface for each SysNode. The takeover network settings are enabled for one network interface:

• Multiple IP address takeover settings are enabled for each network interface.
• Only one node name takeover setting is enabled in a cluster system.

After completing the setup, click Next to go to the "Select Interface" screen.

• Do not configure MAC address takeover for a network interface that uses Web-Based Admin View.
• To activate a network interface card (NIC) when the system is started, you must create the /etc/hostname.NIC-name file. For instructions on creating and setting up the file, see "Solaris X Reference Manual Collection."
• Node name takeover changes the uname of the system. To set node name takeover for userApplication, you need to restart all nodes configuring userApplication.
  If a node name takeover resource has been deleted, check whether /etc/nodename has been properly changed in all nodes, and then restart all nodes. If /etc/nodename has not been properly changed, change the node name by executing the "setuname(1M)" command, and then restart the nodes.
  Also check whether /etc/nodename is set properly when system conversion or software upgrade is implemented. If /etc/nodename is not set properly, change the node name by executing the "setuname(1M)" command, and then restart the nodes.

Selecting an interface

Select a network interface card (NIC).
The NIC cards registered to Cluster Resource Manager are displayed.

[Select interface ]

Interface

Select the network interface to be used in each SysNode.

After completing the setup, click Next to go to the "Select IP address and host name" screen.

Selecting or creating an IP address or host name

Select or create the takeover IP address or host name.

[Select IP address and host name]

New host name

You can set a new takeover IP address and a takeover node name. The setup information is added to the "/etc/inet/hosts" or "/usr/opt/reliant/etc/hvipalias" file on all nodes configuring the cluster system.
Specify a character string of up to 14 characters that begins with an alphabet letter and consists of only alphanumeric characters.

Select host name

You can select the IP address or node name from information that has been set. If IP addresses or node names were previously configured to /etc/inet/hosts and /usr/opt/reliant/etc/hvipalias, select the IP address or node name from those settings.

IP address

Enter the takeover IP address.
Enter 0 to 255 numbers in the address input area.

Netmask

Enter the net mask value.
Enter 0 to 255 numbers in the address input area.

Advanced setup

Set up a masked net mask or change an IP address.

Option button

Press this button to configure attributes for the takeover IP address. For more information, see "Setting up Takeover IP Address Attributes" below.

If /usr/opt/reliant/etc/hvipalias and /etc/inet/hosts files have been modified to accommodate the entries for the takeover IP address and node name takeover in advance (as described in the Prerequisites section), message 0840 appears when the Next button is clicked. This message confirms whether the existing values are to be used without modification. To use the values, select Yes.

If you select No, the existing settings in the file are deleted and the GUI re-creates the information. In this case, takeover network information can be deleted automatically from /usr/opt/reliant/etc/hvipalias and /etc/inet/hosts when the Ipaddress resource is deleted.

Setting up Takeover IP Address Attributes

Configure the interface attributes for the takeover IP address.

[Attribute setup for takeover IP address]

Flag	Outline
BASE	If this flag is set to "base," the specified address is assigned to the physical interface. If this flag is set to "virtual," the specified address is assigned to the virtual interface. The default value is "virtual." [Note] To specify MAC address takeover in the interface attributes of the takeover IP address, change this setting from "virtual" to "base."
AUTORECOVER	If this flag is set to "Yes", RMS automatically attempts to create an interface if the specified address becomes disabled. A failure of this attempt might trigger Fault processing. The default value is "Yes."

After the setup is completed, click OK to return to the "Select IP address and host name" screen.

The availability of the takeover IP address is verified by executing the "ping" command.

We recommend that you specify two or more hosts, which are not used for the cluster system, and are in the same network segment that does not use a hub or router. This prevents adverse effects from hub and router failures.

The host information to be used by PingHost must be in /etc/inet/hosts.

Checking registration information for the takeover network

Check the registration information for the takeover network. You can also set resource attributes by selecting the Attributes tab and switching the screen.

For information on the resource attributes, see "Attributes."

[Confirm registration]

SubApplication button

Select this button to associate a previously created takeover network under the current takeover network. This button can be selected only if there are resources of the same type that can be associated. For setting instructions, see "Resource association" in "Creating Cmdline Resources."

Check the registration information, and then click Registration.
