2nd service console port added, can access everyth...

ldeboer · ‎06-11-2008

Hi Everyone,

I installed a ESX 3.02 server with 4 NICs. I have 1st service console port(10.x.x.11) setup with 3 of the NIC all bond together with my virtual machines running. everything works great with this address.

I added a 2nd service console port(10.x.x.10) to the 4th NIC for backup console port. If I reboot the server or toggle a setting within the 'DNS and Routing configuration' of the 2nd console port, it works great for 20-30mins. After 20-30mins I can still use the Virtual Infrastructure Client to connect by IP address to the 2nd service console port, I can goto any of the TABs except when I try to access the 'Console' tab. I get the error:

Error connecting: Cannot connect to host 10.x.x.10. A connection attempt failed because the connected party did not porperly respond after a period of time, or established connection failed because connected host failed to respond. Do you want to try again?

Can I have both Service Console Ports on the same subnet? Could there be a firewall setting within the ESX settings turning something off after a period of time?

It just confusing me, since both Console ports work great for a period of time, then just the console TAB stops working within the Virtual Infrastructure Client of the 2nd console port after a short period of

time.

Thanks for helping out someone new!

Hello,

If I reboot the server or toggle a setting within the 'DNS and Routing configuration' of the 2nd console port, it works great for 20-30mins.

What do you mean by 'toggle'. Your DNS cache could be timing out, or the DHCP least expiring. How is this vswif configured? You should not have to 'toggle' DNS or routing to get this to work. You may need to add another route but that is it.

What i meant by toggle:

If I go to the Properties of my 2nd vSwitch, then edit the properties of 'service console 2'. (IP address manualy set) so I click the 'Edit' under the 'general tab'. I change the 'Gateway device' from AUTO to VSWIF0, hit the OK button, then change it back to AUTO and hit OK button. The Console tab option on my Virtual machines start working again for all my machines for a bit. Shortly after I start getting the error message when selecting the 'Console Tab'

Hope that's not to hard to follow.

Hello,

Hrmm... Not something you need to do.... You have 2 vswif devices now, correct?

vswif0 and vswif1? Run the following commands from the CLI.

esxcfg-vswif -l

esxcfg-nics -l

esxcfg-routes -l

netstat -rn
