VCS Cluster not starting.

Hello,

Clearly the issue is at LLT layer ... as you can see from llstat output you have posted, node 1 says that node 2 LLT is down, & node 2 says that node 1 LLT is down .. couple of possibilities here

1. Either the physical connection itself has issues, you can use tools like dlpiping or lltping to determine the status of LLT links. These tools are helpful because LLT works at mac layer. Alternatively to test, you can plumb some IPs on both the sides & try test ping. for e.g plumb 1.1.1.1 on nxge1 on node 1 & 1.1.1.2 on nxge1 on node 2 & you can ping to confirm connectivity.

2. If connectivity is found right, just try to start all the components manually on node 1

# /etc/init.d/llt start

# /etc/init.d/gab start

I have observed that sometimes LLT status is now shown correctly unless GAB is started correct. once these are started, check the "gabconfig -a" output again. If GAB starts & shows membership with other node, you will need to start IOFencing

# /etc/init.d/vxfen start

post this you would be able to execute "hastart" in order for VCS to start
