　　在远程不好搞。得去机房了。

IPMP(IP Multipathing)是Solaris操作系统中重要特性，它将几个网络接口绑定在一起作为一个IPMP组，做到网络接口的冗余。即使其中的一个网络接口发生故障，IPMP上的业务IP不会丢失，会failover到其他接口上，避免了单点故障。IPMP可用于Oracle的RAC的公用网络或私有网络上。

基于link的IPMP(Link Based IPMP)

在Solaris中mpathd守护进程负责探测网络接口的故障与修复，它所用的参数配置文件为/etc/default/mpathd。IPMP根据mpathd探测网络接口故障的方法不同，可分为基于link的IPMP和基于probe的IPMP。

基于link的IPMP具有以下特点

–mpathd利用网络接口驱动程序进行探测(需要接口硬件支持)

–不需要额外的测试IP地址，节省IP资源

–默认可用(如果接口硬件支持)

在配置IPMP时，有两种模式：Active-Active模式和Active-Standby模式。在Active-Active模式中所有网络接口都要在线处于active状态；在Active-Standby模式中，至少有一个网络接口在线处于active状态，其他网络接口处于standby状态。查看IPMP组中各个网络接口的状态信息可用ipmpstat命令。

# ipmpstat
usage: ipmpstat [-n] [-o [-P]] -a|-g|-i|-p|-t
  output modes:  -a  display IPMP data address information
                 -g  display IPMP group information
                 -i  display IPMP-related IP interface information
                 -p  display IPMP probe information
                 -t  display IPMP target information
       options:  -n  display IP addresses numerically
                 -o  display only the specified fields, in order
                 -P  display using parsable output mode


在Solaris 11上配置Link Based IPMP示例

1. 设置NCP (network configuration profile) 为DefaultFixed.

# netadm enable -p ncp DefaultFixed
查看ncp是否为DefaultFixed. # netadm list
TYPE        PROFILE        STATE
ncp         DefaultFixed   online
ncp         Automatic      disabled
loc         Automatic      offline
loc         NoNet          offline
loc         DefaultFixed   online

2. 设置IPMP的transitive-probing属性为false

#svccfg -s svc:/network/ipmp setprop config/transitive-probing=false

#svcadm refresh svc:/network/ipmp:default

查看transitive-probing属性

# svccfg -s svc:/network/ipmp listprop config/transitive-probing

config/transitive-probing boolean false

# ipmpstat -p

ipmpstat: probe-based failure detection is disabled

3. Active-Active模式 (以4个网络接口为例)

创建IPMP组ipmp1

# ipadm create-ipmp ipmp1

创建网络接口net2, net3, net9和net10

#ipadm create-ip net2

#ipadm create-ip net3

#ipadm create-ip net9

#ipadm create-ip net10

添加网络接口到ipmp1组中

# ipadm add-ipmp -i net2 -i net3 -i net9 -i net10 ipmp1

查看ipmp1信息

# ipmpstat -g
GROUP       GROUPNAME   STATE     FDT       INTERFACES
ipmp1           ipmp1                 ok            --           net10 net9 net3 net2
# ipmpstat -i
INTERFACE   ACTIVE  GROUP       FLAGS     LINK      PROBE     STATE
net10               yes         ipmp1          -------         up          disabled    ok
net9                 yes         ipmp1          -------         up          disabled    ok
net3                 yes         ipmp1          -------         up          disabled    ok
net2                 yes         ipmp1          --mbM--     up          disabled    ok

为ipmp1设置IP地址

# ipadm create-addr -T static -a 192.168.57.142/24 ipmp1/v4

# ipmpstat -a
ADDRESS                   STATE  GROUP       INBOUND     OUTBOUND
192.168.57.142            up         ipmp1          net2              net10 net9 net3 net2
查看ipmp1的IP地址

# ipadm show-addr

ADDROBJ   TYPE     STATE     ADDR

lo0/v4           static      ok            127.0.0.1/8

ipmp1/v4      static       ok           192.168.57.144/24

4. Active-Standby模式

继续上面的例子，把net9和net10转换为standby

# ipadm set-ifprop -p standby=on -m ip net9

# ipadm set-ifprop -p standby=on -m ip net10

# ipmpstat -i
INTERFACE   ACTIVE  GROUP       FLAGS     LINK      PROBE     STATE
net10              no           ipmp1           is-----        up          disabled    ok
net9                no           ipmp1           is-----        up          disabled    ok
net3                yes         ipmp1           -------         up          disabled    ok
net2                yes         ipmp1           --mbM--     up          disabled    ok

从ifconfig命令输出中可以看到net9和net10有STANDBY标志，处于inactive状态。

# ifconfig -a inet

ipmp1: flags=108001000843<up,broadcast,running,multicast,ipv4,ipmp,physrunning> mtu 1500 index 9
        inet 192.168.57.142 netmask ffffff00 broadcast 192.168.57.255
        groupname ipmp1
net2: flags=100001000843<up,broadcast,running,multicast,ipv4,physrunning> mtu 1500 index 10
        inet 0.0.0.0 netmask ff000000 broadcast 0.255.255.255
        groupname ipmp1
net3: flags=100001000843<up,broadcast,running,multicast,ipv4,physrunning> mtu 1500 index 11
        inet 0.0.0.0 netmask ff000000 broadcast 0.255.255.255
        groupname ipmp1
net9: flags=100061000843<up,broadcast,running,multicast,ipv4,standby,inactive,physrunning> mtu 1500 index 12
        inet 0.0.0.0 netmask ff000000 
        groupname ipmp1
net10: flags=100061000843<up,broadcast,running,multicast,ipv4,standby,inactive,physrunning> mtu 1500 index 8
        inet 0.0.0.0 netmask ff000000 
        groupname ipmp1
