Hi there, Please see my setup in attached file I''ve installed Oracle VM server and created 2 Oracle Linux guest machines ebdb1 and ebdb2 on it to be used as 2 RAC nodes. This machine has only one physical NIC to communicate with outside world. The IP addresses are as follow: 192.168.1.61 ebdb1 192.168.1.62 ebdb2 10.99.1.192 ebdb1-priv 10.99.1.193 ebdb2-priv 192.168.1.71 ebdb1-vip 192.168.1.72 ebdb2-vip Everything is fine here ebdb1 and ebdb2 can ping to each other AND ebdb1-priv and ebdb2-priv can ping to each other. Even they can ping to outside world (www.google.com). I want to use a separate machine as SAN for this RAC. I installed openfiler on Acer AH340-UA230N Easystore which has one onboard NIC (eth0) and a separate PCI express NIC (eth1). The IP addresses of this machine are: 192.168.1.30 aasbanas 10.99.1.191 aasbanas-priv The public interfaces are fine e.g. ebdb1, ebdb2 and aasbanas can ping each other. But private interconnect ebdb1-priv, ebdb2-priv and aasbanas-priv can''t ping to each others. The "ping ebdb1-priv" just hangs on aasbanas machine. The "ping aasbanas-priv" command on both ebdb1 and ebdb2 gives error "Destination Host Unreachable". Can anyone help me to resolve the issue? Thanks a lot. _________________________________________________________________ _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

OK I have established 2 VLANs. One public 192.168.1.1 using router as shown in attached diagram. Other private VLAN using a switch. Now Dom0 and aasbanas can ping on private VLAN. But dom0 and aasbanas can''t ping ebdb1-priv and ebdb2-priv and vice versa. How can domu''s private interconnect can see out side and vice versa?> Date: Fri, 5 Feb 2010 11:46:42 +0700 > Subject: Re: [Xen-users] private interconnect problem > From: fajar@fajar.net > To: jia786@hotmail.com > CC: xen-users@lists.xensource.com > > On Fri, Feb 5, 2010 at 10:12 AM, Javed Asif <jia786@hotmail.com> wrote: > > Hi there, > > > > Please see my setup in attached file > > > > I''ve installed Oracle VM server and created 2 Oracle Linux guest machines > > ebdb1 and ebdb2 on it to be used as 2 RAC nodes.

If yes, then you need a router to connect aasbanas vlan and -priv vlan. Ask your network guys for details. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Thanks Fajar for your replies. You have correctly understood the problem. Actually this is my home network (and I''m newbie admin) so I have to do everything. Are you suggesting to replace the switch with router and configure it for private vlan? Thanks again...

Seriously. Here''s a hint though. If your ONLY problem right now is to make the privs be able to communicate with dom0, Then the easiest way is to probably add another interface (connected to the switch, which is connected to eth1) to your current router, and configure it with IP address 10.99.1.1, and tell the privs to use that IP address as gateway. If you find managing multiple network/vlans too hard, then simply put the privs in the same network as dom0, and give them IP address in the same range. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
