几个ib命令

如下是跟踪IB路径的命令ibtracert的用法

[root@rac1 ~]# ibtracert  1 4
From switch {0x7cfe900300f17940} portnum 0 lid 1-1 "MF0;switch-138276:SX6036/U1"
[33] -> ca port {0x248a0703005d07f1}[1] lid 4-4 "rac2 mlx4_0"
To ca {0x248a0703005d07f0} portnum 1 lid 4-4 "rac2 mlx4_0"


[root@rac1 ~]# ibtracert  1 3
From switch {0x7cfe900300f17940} portnum 0 lid 1-1 "MF0;switch-138276:SX6036/U1"
[31] -> ca port {0x7cfe90030016c231}[1] lid 3-3 "host1 mlx4_0"
To ca {0x7cfe90030016c230} portnum 1 lid 3-3 "host1 mlx4_0"
[root@rac1 ~]# 

如下是报告端口状态的命令：

[root@rac1 ~]# for i in `ls /sys/class/infiniband/*/ports/*/state`; do echo $i; cat $i; done
/sys/class/infiniband/mlx4_0/ports/1/state
4: ACTIVE
/sys/class/infiniband/mlx4_0/ports/2/state
1: DOWN
/sys/class/infiniband/mlx4_1/ports/1/state
4: ACTIVE
/sys/class/infiniband/mlx4_1/ports/2/state
1: DOWN
[root@rac1 ~]#
