90 Manually installing and configuring VCSInstalling VCS software manuallyTable 4-2Directivelinkset-clusterlink-lowpriLLT directivesDescriptionAttaches LLT to a network interface. At least one link is required,and up to eight are supported. The first argument to link is a userdefinedtag shown in the lltstat(1M) output to identify thelink. It may also be used in llttab to set optional static MACaddresses.The second argument to link is the device name of the networkinterface. Its format is device_name:device_instance_number. Theremaining four arguments to link are defaults; these argumentsshould be modified only in advanced configurations. There shouldbe one link directive for each network interface. LLT uses anunregistered Ethernet SAP of 0xCAFE. If the SAP is unacceptable,refer to the llttab(4) manual page for information on how tocustomize SAP. Note that IP addresses do not need to be assignedto the network device; LLT does not use IP addresses.Assigns a unique cluster number. Use this directive when morethan one cluster is configured on the same physical networkconnection. LLT uses a default cluster number of zero.Use this directive in place of link for public network interfaces.This directive prevents VCS communication on the public networkuntil the network is the last link, and reduces the rate of heartbeatbroadcasts. Note that LLT distributes network traffic evenly acrossall available network connections and, in addition to enabling VCScommunication, broadcasts heartbeats to monitor each networkconnection.For more information about LLT directives, refer to the llttab(4) manual page.Additional considerations for LLTYou must attach each network interface that is configured for LLT to a separateand distinct physical network.By default, Sun systems assign the same MAC address to all interfaces. Thus,connecting two or more interfaces to a network switch can cause problems. Forexample, if IP is configured on one public interface and LLT on another, andboth interfaces are connected to a switch, the duplicate MAC address on the twoswitch ports can cause the switch to incorrectly redirect IP traffic to the LLTinterface and vice-versa. To avoid this, configure the system to assign uniqueMAC addresses by setting the eeprom(1M) parameter local-mac-address? totrue.
Manually installing and configuring VCSInstalling VCS software manually91Configuring group membership and atomic broadcast (GAB)To configure GAB, use vi or another editor to set up an /etc/gabtabconfiguration file on each node in the cluster. The following example shows asimple /etc/gabtab file:/sbin/gabconfig -c -nNWhere the -c option configures the driver for use and -nN specifies that thecluster is not formed until at least N systems are ready to form the cluster. Bydefault, N is the number of systems in the cluster.Note: Symantec does not recommend the use of the -c -x option for /sbin/gabconfig. Using -c -x dramatically increases configuration time for theGigabit Ethernet controller and can lead to a split-brain condition.Configuring VCSVCS configuration requires the types.cf and main.cf files on each system in thecluster. Both of the files are in the /etc/VRTSvcs/conf/config directory.main.cf fileThe main.cf configuration file requires the following minimum essentialelements:■■■An “include” statement that specifies the file, types.cf, which defines theVCS bundled agent resources.The name of the cluster.The name of the systems that make up the cluster.Editing the main.cf fileWhen you manually install VCS, the file /etc/VRTSvcs/conf/config/main.cfcontains only the line:include "types.cf"To edit the main.cf file1 Log in as superuser, and move to the directory containing the configurationfile:# cd /etc/VRTSvcs/conf/config2 Using vi, or another text editor, edit the main.cf file, defining your clustername and system names. Refer to the following example.3 Save and close the file.
