Hi,
I have a couple of questions about IPoIB loading and starting.
1. It appears I need the following modules in this order:
core/ib_client_query.ko
core/ib_sa_client.ko
ulp/ipoib/ib_ipoib.ko
ulp/ipoib/ib_ip2pr.ko
Any others ? I presume ib_pr2pr is needed. What happens if it is not present ?
ib_ip2pr is not needed for normal operation. modprobe ib_ipoib should pick up all the dependencies (if you have the modules installed in /lib/modules/`uname -r`)
2. After all the above modules are loaded, do I just configure the ib0/1 interfaces ?
Something like:
/sbin/ifconfig ib0 192.168.0.101 netmask 255.255.255.0 up
Yup.
Does anything else need to be done before it should work (other than an SM bringing these links to active) ?
It also depends what pkey your subnet manager uses for the IP network. Sun's setup uses pkey 0x8001, so I need to setup a virtual NIC using the ipoibcfg command.
I would have thought this would be part of the IP over IB driver. Communicate with the SM to acquire the P_Key and then use that to perform Arp / ND. Strange to require a command since this gets a bit cumbersome when there are many nodes in the fabric.
