Configuring an IB Interface at Bringup
I've searched the archives but will admit to being a bit of a n00b here
:( So apologies if this is covered. I'm using the Sun HPC distro but
it's not supported anymore. I've found adding an IB interface to deal
with IP over IB isn't working well for me. I configured the system with
a single ethernet port that I boot off of (diskless), it works well
{'eth0': {'bonding': '',
'bonding_master': '',
'bonding_opts': '',
'dhcp_tag': '',
'dns_name': 'pga-n0',
'ip_address': '10.10.10.20',
'mac_address': '00:xx:yy:zz:aa:bb',
'static': 'True',
'static_routes': [],
'subnet': '255.255.255.0',
'virt_bridge': ''},
Once it was up, I wanted to add an additional interface to the system in
cobbler to bring up an IP address on the IB card, ib0. I grabbed the
hwaddr off of the ifconfig from the system (I also tried the port guid)
and added the interface:
cobbler system edit --name=pga-n0 --mac=
80:00:00:xx:yy:zz:00:00:00:00:00:00:00:00:00:00:00:00:00:00
--ip=10.13.90.10 --subnet=255.255.2550.0 --hostname=pga-n0-ib0
--interface=ib0 --dns-name=pga-n0-ib0
No luck. Has anyone brought up an IB port on a diskless system?
