This means that either LLT or GAB is not running on any of the nodes or that there is no network connection through the LLT links.

Please check and start:

To check:

#gabconfig -a

#lltconfig

#lltstat -nvv

to start:

To test LLT links:

To start HAD demon GAB needs to be seeded.

Hi Zahid,

I think the problem caused by you start GAB by "gabconfig -c -x". Restart GAB by :

gabconfig -U

sh /etc/gabtab

Maybe this will help.

Hi Zahid,

Is the version same on both the nodes ? If yes,

I would suggest to stop the entire stack & try once again from bottom up approach

On both the nodes

# gabconfig -U   (unconfigure gab)

# modinfo |grep -i gab  (find module ID for gab)

# modunload -C <gab_module ID>

# lltconfig -U  (unconfigure LLT)

# modinfo |grep -i llt  (find module ID for LLT)

# modunload -C <LLT_module_id>

Start again

# /etc/init.d/S70llt start     OR # lltconfig -C

# lltconfig    (it should say  "LLT is running)

# /etc/init.d/S92gab start   OR #gabconfig -C

now check status of gab whether you have both the ports in gab

If you still face issues, check the LLT communication as suggested by Dan ..

FYI--

An alternative to Gaurav's instructions on how to restart the entire VCS stack, I find it more convenient and possibly more comprehensive to use the CPI to do the same:

# /opt/VRTS/install/installvcs601 -stop  # stops  all drivers and processes of a product
# /opt/VRTS/install/installvcs601 -start # starts all drivers and processes of a product

But as others have already pointed out, it is important to confirm your LLT configuration before taking other steps.  'lltstat -nvv active' should show you whether LLT is working; no point doing anything else until you have resolved that...  Then move on to GAB.  

Of course, 'hastatus' is still going to show you the error as you have shown unless it is already running, so you need to start 'had' before issuing an 'hastatus' command...
