You now configure the private heartbeat links that LLT uses. VCS provides the option to use LLT over Ethernet or over UDP (User Datagram Protocol). Symantec recommends that you configure heartbeat links that use LLT over Ethernet for high performance, unless hardware requirements force you to use LLT over UDP. If you want to configure LLT over UDP, make sure you meet the prerequisites.
See Using the UDP layer for LLT.
The following procedure helps you configure LLT over Ethernet.
To configure private heartbeat links
Choose one of the following options at the installer prompt based on whether you want to configure LLT over Ethernet or UDP.
Option 1: LLT over Ethernet (answer installer questions)
Enter the heartbeat link details at the installer prompt to configure LLT over Ethernet.
Skip to step 2.
Option 2: LLT over UDP (answer installer questions)
Make sure that each NIC you want to use as heartbeat link has an IP address configured. Enter the heartbeat link details at the installer prompt to configure LLT over UDP. If you had not already configured IP addresses to the NICs, the installer provides you an option to detect the IP address for a given NIC.
Skip to step 3.
Option 3: Automatically detect configuration for LLT over Ethernet
Allow the installer to automatically detect the heartbeat link details to configure LLT over Ethernet. The installer tries to detect all connected links between all systems.
Skip to step 5.
The installer discovers and lists the network interface cards.
Answer the installer prompts. The following example shows different NICs based on architecture:
For Solaris SPARC:
You must not enter the network interface card that is used for the public network (typically bge0.)
Enter the NIC for the first private heartbeat link on sys1: [b,q,?] bge0 Would you like to configure a second private heartbeat link? [y,n,q,b,?] (y) Enter the NIC for the second private heartbeat link on sys1: [b,q,?] bge1 Would you like to configure a third private heartbeat link? [y,n,q,b,?](n)
Do you want to configure an additional low priority heartbeat link? [y,n,q,b,?] (n)
For Solaris x64:
You must not enter the network interface card that is used for the public network (typically e1000g0.)
Enter the NIC for the first private heartbeat link on sys1: [b,q,?] e1000g1 Would you like to configure a second private heartbeat link? [y,n,q,b,?] (y) Enter the NIC for the second private heartbeat link on sys1: [b,q,?] e1000g2 Would you like to configure a third private heartbeat link? [y,n,q,b,?](n)
Enter the NIC for the first private heartbeat link on sys1: [b,q,?] private_NIC1 Do you want to use address 192.168.0.1 for the first private heartbeat link on sys1: [y,n,q,b,?] (y) Enter the UDP port for the first private heartbeat link on sys1: [b,q,?] (50000) ? Would you like to configure a second private heartbeat link? [y,n,q,b,?] (y) Enter the NIC for the second private heartbeat link on sys1: [b,q,?] private_NIC2 Do you want to use address 192.168.1.1 for the second private heartbeat link on sys1: [y,n,q,b,?] (y) Enter the UDP port for the second private heartbeat link on sys1: [b,q,?] (50001) ? Do you want to configure an additional low priority heartbeat link? [y,n,q,b,?] (n) y Enter the NIC for the low priority heartbeat link on sys1: [b,q,?] (private_NIC0) Do you want to use address 192.168.3.1 for the low priority heartbeat link on sys1: [y,n,q,b,?] (y) Enter the UDP port for the low priority heartbeat link on sys1: [b,q,?] (50004)
Are you using the same NICs for private heartbeat links on all systems? [y,n,q,b,?] (y)
If you want to use the NIC details that you entered for sys1, make sure the same NICs are available on each system. Then, enter y at the prompt.
For LLT over UDP, if you want to use the same NICs on other systems, you still must enter unique IP addresses on each NIC for other systems.
If the NIC device names are different on some of the systems, enter n. Provide the NIC details for each system as the program prompts.
If the installer fails to detect heartbeat links or fails to find any high-priority links, then choose option 1 or option 2 to manually configure the heartbeat links.
Enter a unique cluster ID number between 0-65535: [b,q,?] (60842)
The cluster cannot be configured if the cluster ID 60842 is in use by another cluster. Installer performs a check to determine if the cluster ID is duplicate. The check takes less than a minute to complete.
Would you like to check if the cluster ID is in use by another cluster? [y,n,q] (y)
