88 Manually installing and configuring VCSInstalling VCS software manuallyFrom the output, you can determine the license key, the type of license, theproduct for which it applies, and its expiration date, if any. Demo keys haveexpiration dates, while permanent keys and site keys do not.Upgrading the configuration filesYou need to restore the configuration files from your previous VCS installationif you manually added 5.0 packages to upgrade your cluster to VCS.Installing the Cluster ManagerIf you did not install Cluster Manager (the VCS Java-based graphical userinterface package), VRTScscm, you can do it later.Copying the installation guide to each nodeConfiguring LLT and GABAfter you install VCS, Symantec recommends that you copy the PDF version ofthis guide from the installation disc (cluster_server/docs/vcs_install.pdf) to thedirectory /opt/VRTS/docs on each node to make it available for reference.VCS uses LLT and GAB to replace the functions of TCP/IP for VCS privatenetwork communications. LLT and GAB provide the performance and reliabilityrequired by VCS for these and other functions.LLT and GAB must be configured as described in the following sections.Configuring low latency transport (LLT)To configure LLT, set up two files: /etc/llthosts and /etc/llttab on each node inthe cluster.Setting up /etc/llthostsThe file llthosts(4) is a database, containing one entry per system that links theLLT system ID (in the first column) with the LLT host name. You must create anidentical file on each node in the cluster.Use vi, or another editor, to create the file /etc/llthosts that contains entries thatresemble:0 north1 south
Manually installing and configuring VCSInstalling VCS software manually89Setting up /etc/llttabThe /etc/llttab file must specify the system’s ID number (or, its node name), and the network links that correspond to the system. In addition, the file can contain other directives. Refer also to the sample llttab file in /opt/VRTSllt.See “LLT directives” on page 89.Using vi or another editor, create the file /etc/llttab that contains entries thatresemble:set-node northset-cluster 2link e1000g0 e1000g:0 - ether - link e1000g1 e1000g:1 - ether - The first line must identify the system on which the file exists. In the exampleabove, the value for set-node could be north, 0, or the file name /etc/nodename,provided the file contains the name of the system (north in this example). Thenext two lines, beginning with the link command, identify the two privatenetwork cards that the LLT protocol uses. The order of directives must be thesame as in the sample file /opt/VRTSllt/llttab.LLT directivesFor more information about LLT directives, refer to the llttab(4) manual page.Table 4-2Directiveset-nodeLLT directivesDescriptionAssigns the system ID or symbolic name. The system ID numbermust be unique for each system in the cluster, and must be in therange 0-31. The symbolic name corresponds to the system IDlisted in /etc/llthosts file.Note that LLT fails to operate if any systems share the same ID.
