Symantec VERITAS Cluster - Heartbeat on HP Blade server

Hello,

Please read through below posts,

Also, from the technote

Q:  I have blade servers, with just two shared NICs for each chassis.  What's the best way to configure my interconnect?

A:  Symantec recommends dedicating one of the shared NICs to a private LLT connection, and using the second shared NIC as the public interface, with a lowpri LLT link connection configured.

The key thing is to make sure your llt heartbeat links are independent, and as you only have 2 physical interfaces you should only have 2 heartbeats, therefore I would recommend the following:

1. Create 2 virtuals in each of the physical interfaces, so for example you have:
   virtual interfaces A1 and A2 on physical interface A
   virtual interfaces B1 and B2 on physical interface B
    
2. Create bond for public interface using A1 and B1
    
3. Use A2 and B2 as 2 high-pri (normal) heartbeats
    
4. Do not configure a low-pri heartbeat.
