 .

my host entry is:-uatdata1

192.168.6.6     uatdata2        uatdata2.mpmkvvcl.com

##***Private IP Addresses ***

15.1.1.1        uatdata1-priv   uatdata1-priv.mpmkvvcl.com

15.1.1.2        uatdata2-priv   uatdata2-priv.mpmkvvcl.com

## *****Cluster VIP's*****

192.168.6.25    uatdata1-vip    uatdata1-vip.mpmkvvcl.com

192.168.6.26    uatdata2-vip    uatdata2-vip.mpmkvvcl.com

##*************application server****************

192.168.5.5     uatapp1         uatapp1.mpmkvvcl.com

192.168.5.6     uatapp2         uatapp2.mpmkvvcl.com

My another host entry is uatdata2:-

127.0.0.1       localhost       loopback

 192.168.4.5    prodata1     prodata1.mpmkvvcl.com

192.168.4.6    prodata2      prodata2.mpmkvvcl.com

##***Cluster Node IP Address ***

192.168.6.5  uatdata1           uatdata1.mpmkvvcl.com

192.168.6.6 uatdata2          uatdata2.mpmkvvcl.com

 ##***Private IP Addresses ***

15.1.1.1        uatdata1-priv          uatdata1-priv.mpmkvvcl.com

 15.1.1.2        uatdata2-priv          uatdata2-priv.mpmkvvcl.com

 ## *****Cluster VIP's*****

192.168.6.25  uatdata1-vip           uatdata1-vip.mpmkvvcl.com

192.168.6.26   uatdata2-vip          uatdata2-vip.mpmkvvcl.com

 ##******application server****************

192.168.5.5     uatapp1          uatapp1.mpmkvvcl.com

 192.168.5.6     uatapp2          uatapp2.mpmkvvcl.com

192.168.2.3     appsdev2         appsdev2.mpmkvvcl.com

Example:

ping uatdata1-vip.mpmkvvcl.com

not reply

(Both nodes are proper host entry but not vip addresses pinging each other )

other address ping each other but vip address not pinging

(VIP address is a cluster ip address)

Its a cluster ip

How can resolved that problem.

Thanks

You probably need to check your DNS set up.  My guess is that the system is querying a DNS server that has an incorrect entry for this host.

Try using 'nslookup' or 'nsquery' to see what exactly is happening.  For example:

nslookup uatdata1-vip.mpmkvvcl.com

or

nsquery uatdata1-vip.mpmkvvcl.com

You should also check your /etc/resolv.conf file and see what DNS server(s) you are using.  You can also check /etc/nsswitch.conf to see what order things are queried in (probably DNS, then files).

If you are querying DNS first the you need to check the DNS servers specified in /etc/resolv.conf and make sure they have the correct IP addresses configured for these hosts.

I don't know about your network, but it looks like you have more than 1 NIC on the same subnet - this causes problems!

Check my reply in your other thread: http://h30499.www3.hp.com/t5/Networking/Host-name-ping-to-another-ip/m-p/5434741

I think you may have host to IP resolution problems.

Can you ping via the IP address rather than the host name?

[aamir4u]

hello.

I try to ping to ip address but its also not pinging.(only vip address)another ip ping each other.

How can ping servers each other to vip address.

Please help me.

[aamir4u]

I dont know what are you saying.

I already send my ip host file on trail mail.

day after Yesterday its was ping each other.

but today i restarted serviceguard on both nodes(uatdata1 and uatadata2)

after restarted serviceguard its vip address not ping each other

and

nslookup shows all details properly.

What is a problem.how can we solve that problem.

Thank for future

Are you sure your packages and their virtual IP addresses are up and configured?

If you do a 'netstat -in' on each server in the cluster do you see the appropriate IP addresses?

Does 'cmviewcl -v' show all packages to be up and running?

[aamir4u]

Hi,

When i run that commands the output are following:..

uatdata1 /#netstat -in

is first service guard up than

vip address ping each others ?

So,

How can solved that.

Thanks
