871820 - please add dhcp helper for 10.26.16.0

Status: RESOLVED FIXED

(Infrastructure & Operations Graveyard :: NetOps, task)

Description

[Amy Rich [:arr] [:arich]]

Please add a dhcp helper for 10.26.16.0/22 that points to 10.26.75.40, 10.26.75.41.  This will enable dhcp for the inband.releng.scl3.mozilla.com network.

The helper is already in place - the DHCP servers are giving errors for requests on that VLAN:

So this just needs the DHCP configuration.

er, I didn't mean to take the bug, although I can do the DHCP config tomorrow if necessary,.

Confirmed; I saw 4 machines pick up addresses as of May 13 17:06 pacific.

Comment 5

[Amy Rich [:arr] [:arich]]

Well, actually, the last lease renewal I saw was May 16 00:34:09.  I tried rebooting one of the IPMI devices and I never saw a request for it come across to the dhcp servers.  Either the reboot didn't work (possible), or the helper was functioning before and is not now.

The DHCP helpers are still in place. I can help troubleshoot, but as far as this going from working to not working, nothing appears to have been altered on the FW.

[Amy Rich [:arr] [:arich]]

Augh, I picked the ns IPs, not the admin host IPs.  My mistake.  Adam was awesome and troubleshot and fixed.
