connectivity issue
Hi,
I am having strange network issue, we have two Hp-UX 11.31servers, both the servers are in same IP segment, successfully setup passwordless SSH communication between both the servers, I can connect via ssh without giving password to the second server and vice versa, but suddenly with no change the both the servers cannot ping/SSH each other, although I am connected to both the servers from my machine using SSH.
Server 1 --> HISTST01:

I have to setup seemless connectivity for these servers for Oracle RAC environment.

Re: connectivity issue
Hi,

- so I understand ssh is working but ping not working.
- Also what is the OS version.
- Can you do a linkloop test between two server adapter. HISTST01 & HISTST02
from # linkloop -i <PPA> <MAC>
if it says OK that means network level the connection between these two server is fine. And ping /ssh should not have any problem.
HTH,
Raj D.

Re: connectivity issue
Hi,
No even SSH is not working along with the ping.
linkloop between these two servers is OK.
HISTST01 -> / # ping 10.241.16.102
PING 10.241.16.102: 64 byte packets
----10.241.16.102 PING Statistics----
20 packets transmitted, 0 packets received, 100% packet loss
HISTST01 -> / # linkloop -i 0 0x1CC1DE3F30F2
Link connectivity to LAN station: 0x1CC1DE3F30F2
-- OK
HISTST02:/# ping 10.241.16.101
PING 10.241.16.101: 64 byte packets
----10.241.16.101 PING Statistics----
44 packets transmitted, 0 packets received, 100% packet loss
HISTST02:/# linkloop -i 0 0x1CC1DE3F3076
Link connectivity to LAN station: 0x1CC1DE3F3076
-- OK
Thanks.

Re: connectivity issue
Hi,
Actually the issue was IP Address conflict, changed the IP address to resolved the issue.
Thanks.
