I thought this would be a quick change, and it appears that we are still down. The public connection (mac 00.25.90.03.eb.80) for the load balancer is supposed to be on a "special" vlan, I'm not sure of the id, but it is the vlan with the 140.221.15.1 gateway. It doesn't look like it is on that vlan, instead from a tcpdump it looks like it on the 808 vlan. ---- Daniel Murphy-Olson Systems Administrator Mathematics & Computer Science Division Argonne National Laboratory 630-252-0055 ----- Original Message ----- From: "Brandon L.

Dan,
I've got the ports for your load balancers marked and will save those for last, I should be ready to move them around 11:00 on Saturday. We could also move them before Saturday if you wanted, the new equipment is already in place and ready to go.

I'll also be onsite doing other work that day, so I can help troubleshoot issues if they arise. I would like to do the load balancers two connections last. 6 net load balancer address is 00:25:90:03:EB:81 15 net load balancer address is 00:25:90:03:EB:80

I don't think there is much that we can do, we're going to have to take this outage. Is the 4k going to reboot, or is it something upstream that is being worked on?

We will be replacing network hardware, which will affect the server infrastructure MCS has in 221 on Saturday 5/18 between 10am and 2pm. What needs to be done ahead of time to prepare for this?
