Cluster Server 7.3.1 Configuration and Upgrade Guide - Solaris

Last Published: 2019-04-17

Product(s): InfoScale & Storage Foundation (7.3.1)

Platform: Solaris

Setting up /etc/llttab for a manual installation

The /etc/llttab file must specify the system's ID number (or its node name), its cluster ID, 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.

Run the dladm show-dev command to query all NICs.

Use vi or another editor to create the file /etc/lltab that contains the entries that resemble the following:

For Solaris 11 SPARC:

    set-node sys1
    set-cluster 2
    link net1 /dev/net/net0 - ether - -
    link net2 /dev/net/net1 - ether - -

Use vi or another editor to create the file /etc/lltab that contains the entries that resemble the following:

For x64:

    set-node sys1
    set-cluster 2
    link e1000g0 /dev/e1000g:0 - ether - -
    link e1000g1 /dev/e1000g:1 - ether - -

The first line must identify the system where the file exists. In the example, the value for set-node can be: sys1, 0, or the file name /etc/nodename. The file needs to contain the name of the system (sys1 in this example). The next line, beginning with the set-cluster command, identifies the cluster number, which must be a unique number when more than one cluster is configured on the same physical network connection.The next two lines, beginning with the link command, identify the two private network cards that the LLT protocol uses. The order of directives must be the same as in the sample llttab file in /opt/VRTSllt.

If you use different media speed for the private NICs, Veritas recommends that you configure the NICs with lesser speed as low-priority links to enhance LLT performance. For example:

Use vi or another editor to create the file /etc/lltab that contains the entries that resemble the following:

For SPARC:

    set-node sys1
    set-cluster 2
    link net1 net:0 - ether - -
    link net2 net:1 - ether - -
    link-lowpri qfe2 qfe:2 - ether - -

Use vi or another editor to create the file /etc/lltab that contains the entries that resemble the following:

For x64:

    set-node sys1
    set-cluster 2
    link e1000g0 /dev/e1000g:0 - ether - -
    link e1000g1 /dev/e1000g:1 - ether - -
    link-lowpri e1000g2 /dev/e1000g:2 - ether - -
