I have a question regarding the def...Hi Santosh,<br /><br /> I have a question regarding the default gateway. From your explaination it looks like our HACMP node's default gateway is not configured properly. Below is a small description of our environment<br /><br />Environment : 3 LPARs ( host 1a, host 1b and host2).<br /> Host 1a and 1b are hacmp nodes with host 1a being the active node<br /> <br />Host 1a has 3 network interfaces (en0, en1 and en2)<br /> en1 – persistent ip<br /> en2 – service ip allocated to it.<br />Host 1a and 1b are on subnet A and host 2 is on subnet B.<br /><br />Issue: can’t mount a FS exported from host 1a on host2 using service ip address of host 1a.<br /><br />On host 2 need to run:(example)<br />mount service_ip_host_1a:/home/Bharath/file1 /tmp<br /><br />NOTE:<br />Host1a routing table: default route is going through en1 (persistent ip) interface. So what ever packet transmitted to host2 goes through en1 (even if host 1a receives packet on interface en2-service ip)<br /><br />any suggestion for this<br /><br />Thanks<br />BharathUnknownhttps://www.blogger.com/profile/14890755527113827481noreply@blogger.comtag:blogger.com,1999:blog-4888604520727443281.post-92212004769905249092008-10-14T18:07:00.000+05:302008-10-14T18:07:00.000+05:30Thanks for the default gateway tip.

When it came back up in the new location, I realized I had forgotten to change the deafult route prior to moving it. The interface was configured correctly, but you could not ping the server or get network services like NIS to work. As soon as I used chdev to add my default route, bingo! Everything started talking. Again, thank you for taking the time to write this down.cbish68https://www.blogger.com/profile/07926301193252195226noreply@blogger.com
