MellanoxConnectX-3HCA中OpenSUSE Leap 42.2中ib谓词的问题

Question

解出

我在OpenSUSE存储库中设置infiniband软件时遇到了麻烦。

同样的卡可以在SLES12 + Mellanox堆栈中正常工作。

从yast安装包含“infiniband”的所有内容--我看到HCA已经启动，并且像ibnode这样的诊断工具会显示相关数据：

>ibnodes
Ca      : 0x0002c90300a00360 ports 2 "cnode1 HCA-1"
Ca      : 0x0002c90300ea8fd0 ports 1 "helper1 mlx4_0"
Switch  : 0x0008f1050020096c ports 36 "Voltaire 4036 # spine2" enhanced port 0 lid 17 lmc 0

这里，helper1是一台OpenSUSE机器，cnode1是一个SLES节点。

但是当谈到动词时，我得到：

>ibv_devinfo
No IB devices found

因此，我无法让MPI使用infiniband。

我是缺少了一些中间层，还是libib谓词组件需要一些额外的配置？

谢谢!

UPD:来自zypper和lsmod的更多输出：

UPD2:正如德里克·米切尔所写的，我可以在SLES+Mellanox OFED中看到服务开放：

>service openibd status
openibd.service - openibd - configure Mellanox devices
   Loaded: loaded (/usr/lib/systemd/system/openibd.service; enabled)
   Active: active (exited) since Thu 2017-03-23 17:45:38 MSK; 1 weeks 2 days ago

 Main PID: 678 (code=exited, status=0/SUCCESS)
   CGroup: /system.slice/openibd.service

Leap 42.2中没有这样的服务，但是有rdma服务，而是：

service rdma status

   Loaded: loaded (/usr/lib/systemd/system/rdma.service; disabled; vendor preset: disabled)

无论如何，ibv_devinfo仍然找不到connectx-3卡.

因此，这个问题是由Leap 42.2主存储库(不包括libmlx4-rdmv 2包)引起的，而mlx4是connectx-3 HCA的驱动程序。

添加工厂后的存储库

zypper addrepo http://download.opensuse.org/repositories/OFED:Factory/openSUSE_Leap_42.2/OFED:Factory.repo

安装libmlx4-rdmv 2并将所有其他infiniband包降级为Factory版本，我开始使用ibv_devinfo。

Answer 1

我这样做是为了我的扑克牌VOLTAIRE 410-4 4EX(麦加)在leap 42.1上：

zypper install opensm ibutils ibutils-devel infiniband-diags infiniband-diags-devel libibcm1 libibverbs-devel libibverbs-runtime ibacm libibcm1 libmthca-rdmav2 rdma tvflash libibnetdisc5 ibsim qperf

然后：

systemctl enable openibd

systemctl start  openibd
