To configure private heartbeat links

1. Choose one of the following options at the installer prompt based on whether you want to configure LLT over Ethernet or LLT over UDP.

   • Option 1: Configure the heartbeat links using 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: Configure the heartbeat links using 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.

     Note:

     Option 3 is not available when the configuration is a single node configuration.

2. If you chose option 1, enter the network interface card details for the private heartbeat links.

   The installer discovers and lists the network interface cards.

   You must not enter the network interface card that is used for the public network (typically en0 en1.)

   Enter the NIC for the first private heartbeat link on sys1:
   [b,q,?] en2
   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,?] en3
   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)

3. If you chose option 2, enter the NIC details for the private heartbeat links. This step uses examples such as private_NIC1 or private_NIC2 to refer to the available names of the NICs.

   Enter the NIC for the first private heartbeat link on sys1: [b,q,?]
   private_NIC1
   Some configured IP addresses have been found on 
   the NIC private_NIC1 in sys1,
   Do you want to choose one for the first private heartbeat link? [y,n,q,?] (y)
   Please select one IP address:
        1)  192.168.0.1/24
        2)  192.168.1.233/24
        b)  Back to previous menu
   
   Please select one IP address: [1-2,b,q,?] (1)
   Enter the UDP port for the first private heartbeat link on sys1:
   [b,q,?] (50000)
   
   Enter the NIC for the second private heartbeat link on sys1: [b,q,?]
   private_NIC2
   Some configured IP addresses have been found on the 
   NIC private_NIC2 in sys1,
   Do you want to choose one for the second 
   private heartbeat link? [y,n,q,?] (y)
   Please select one IP address:
        1)  192.168.1.1/24
        2)  192.168.2.233/24
        b)  Back to previous menu
   
   Please select one IP address: [1-2,b,q,?] (1) 1
   Enter the UDP port for the second private heartbeat link on sys1:
   [b,q,?] (50001)
   
   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) y
   
   Enter the NIC for the low-priority heartbeat link on sys1: [b,q,?]
   private_NIC0
   Some configured IP addresses have been found on 
   the NIC private_NIC0 in sys1,
   Do you want to choose one for the low-priority 
   heartbeat link? [y,n,q,?] (y)
   Please select one IP address:
        1)  10.200.59.233/22
        2)  192.168.3.1/22
        b)  Back to previous menu
   
   Please select one IP address: [1-2,b,q,?] (1) 2
   Enter the UDP port for the low-priority heartbeat link on sys1: 
   [b,q,?] (50010)

4. Choose whether to use the same NIC details to configure private heartbeat links on other systems.

   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.

5. If you chose option 3 , the installer detects NICs on each system and network links, and sets link priority.

   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.

   See step 2 for option 1, or step 3 for option 2 or step 5 for option 3.

6. Enter a unique cluster ID:

   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)

7. Verify and confirm the information that the installer summarizes.
