Unable to ping IVM (HPUX11iV2) from Solaris 8

[Mohammad Sanaullah]

Dear All

I came to an interesting situation, which need immediate attention, please help to resolve the same.

1. I have one SUN 5.8 Server running Oracle 9 as DB and team Center applications.

2. This server is communicating to all the server in our Data Center except the one Physical HPUX server which is having two virtual Guest server (Running same HPUX 11iV2). Which even unable to ping the HPUX server.

3. That IVM machine (One physical (Host) and other two guest servers) communicates to all the server except the one SUN 5.8 (Unable to even ping the server).

Please advice, what ends to check and what??

Bonjour Mohammad,

Have you configured vlan in the virtual switches ?

Anyway, don't think it is VM related, since you can't communicate between the physical HP-UX VM host and the Solaris system, though these 2 systems can communicate with all of others servers. Right ?

Before working at VM level, I think you should first resolve why HP-UX server and solaris don't communicate. Are they on the same IP subnet ? I yes, is the subnet mask right the same ?

Thanks for prompt response, Yes dear both are in same subnet mask, same IP series, each Solaris and HPUX (Physical as well as guests) are communicating to all other server in data center except each other.

ping from HPUX Host to Sun 5.8 >>> failed
ping from HPUX Guests to Sun 5.8 >>> failed

Ping from Sun 5.8 to HPUX Host >>> Failed
Ping from Sun 5.8 to HPUX Guest >>> Failed

Where as All these server are cummunicating to all other servers.

Any clue??

...

Well, please post from HP-UX server :

hpvmnet -V
netstat -in
netstat -rnv

and from each VM Guest
netstat -in
netstat -rnv

If the ping is not working from HP-UX host to Solaris and vice-versa, check if IP filter is running

Try to disable it and check
/opt/ipf/bin/ipfilter -d

Oops.. sorry forgot to read the post completely.
If HP-UX host can ping to other hosts, then there is no issue with IP filter.

## This might be an issue with the Firewall.
## There might be that the packets are going via gateway instead of directly reaching the host.

Since this happens on both the OS, I beleive you could check if ICMP port is blocked between these two servers
