spanning tree portfast settings for PXE booting

In continuation to the previous page on Mirantis Fuel --  while we were setting up openstack  on HP DL 380 G7s  using Fuel - we observed that the nodes were timing out on DHCP during the PXE booting --  as with any Linux Kickstarts we recalled to set 'spanning-tree portfast ' on the cisco switch port use for PXE on the node - and we could resolve the timeout issues

Cheers!!

Mirantis Fuel – provisioning a HP DL 380 G7

hi – My colleague Purna and I ventured into trying to use Mirantis Fuel to provision a private cloud using Hp DL 380 G7s and 380 G6s

We installed the Fuel management station on a VM – then tried to bootstrap the G7 server by allowing it to PXE boot – the server was not getting detected in the fuel dashboard – troubleshooting revealed that hit the following bug with bnx2 and centos — workaround is also documented below -
———————
kernel 3.4 is missing broadcom bnx2 NIC firmware file
“bnx2/bnx2-mips-09-6.2.1b.fw” so for example Dell R510 server NICs
fail to work out of the box. Note that this is an upstream kernel.org
problem. In kernel dmesg you’ll see an error like: “bnx2: Can’t load
firmware file “bnx2/bnx2-mips-09-6.2.1b.fw””. To workaround the
problem do: “cd /lib/firmware/bnx2 && ln -s bnx2-mips-09-6.2.1a.fw
bnx2-mips-09-6.2.1b.fw”. After that “ifdown ethX && ifup ethX” should
work.
