Dear colleagues ! I've some problem w/Mellanox IB software installation (in particular, the absence of xp0 kernel module). I've installed Infiniband HCA (PCI-X Infinihost MT23108 low profile) to upgarde my interconnect on Tyan S2880 under SuSE Linux 9.0 (2.4.21-243). It's official software platform supported by whole Mellanox IBHPC-0.5.0 software collection. 1)After minor source modification (in mosal.c) the installation (INSTALL script) was finished successfully. But after reboot I see that a) mst tools started successfully b) and I see then following boot messages: Setting up network interfaces : eth0 eth1 - both done ib0: modprobe: modprobe: can't locate module xp0 and ib0 interface is down (it's not connected through IB cable really). But I may do ib0 up manually; in particular, /etc/init.d/network start put ib0 in "up" state. I didn't find xb0.o in /lib/modules, and in any Mellanox software rpm's also ! What should I do now - and what/where is xp0 module ?? 2) I configured IPoIB at the installation. (To try IBsNice) I issued vapi start after boot, and see the message Loading mod_ib_mgt FAILED ("manual" modprobe mod_ib_mgt leads to init_module: device or reesource busy) If I run IBsNice, then I receive the same message about mod_ib_mgt but IBsNice create virtual eth2 , and ping to the IP of eth2 works normally. I'll be very appreciate if somebody clarify me this situation w/mod_ib_mgt ! 3) TO BE MORE CORRECT: pls take into account, that my host w/installed software& Mellanox hardware *isn't connected* currently with IB switch (i.e. is "standalone" server !)
