第一、ODM部分

1. 安装前准备工作

说明：一般情况下，AIX自带的FC驱动也可以让AIX正常识别出EMC的磁盘，但是会显示为other FC disk之类，这样powerpath是无法管理的，所以要加装ODM。

获取EMC ODM文件

1、下载EMC odm文件，这是针对emc在aix提供的驱动。下载地址：/pub/elab/aix/ODM_DEFINITIONS

2. 安装配置过程

1、下载的文件类型这个名字：.Z，通过FTP传到AIX上。使用binary的方式传，否则无法解压。

2、 gzip –d，tar xvf命令接包。

3、解包之后用installp命令。

4、安装的时候重点先看看包里面的readme文件，里面重点提到的是不管链接那种EMC设备都只能安装一种support软件，对于symmetric而言，只能安装如下3种文件的任意1种。

EMC Symmetrix FCP Support Software; IBM Fibre Channel driver support.

EMC Symmetrix FCP MPIO Support Software; IBM default PCM MPIO support.

EMC Symmetrix FCP PowerMPIO Support Software; PowerPath custom PCM MPIO support.（这次测试大部分时间都耗在这个问题上，以前没有认真看readme，把全部的fileset都全部安装了。一旦把全部fileset安装上，根本无法识别sysmmetrix的盘，这样导致了后面的powerpath也就无法做了费了2天时间啊。）

5、安装结果如下：

# lslpp -l |grep EMC.*

5.3.0.1 COMMITTED EMC Symmetrix AIX Support

5.3.0.1 COMMITTED EMC Symmetrix FCP Support

6、如果EMC盘已经在系统上被识别出来了比如：

# lsdev -Ccdisk

hdisk0 Available 11-08-00-2,0 16 Bit LVD SCSI Disk Drive

hdisk1 Available 11-08-00-4,0 16 Bit LVD SCSI Disk Drive

hdisk2 Available 3A-08-01 MPIO Other FC SCSI Disk Drive

hdisk3 Available 3A-08-01 MPIO Other FC SCSI Disk Drive

4/8/2013

hdisk4 Available 3A-08-01 MPIO Other FC SCSI Disk Drive

hdisk5 Available 3A-08-01 MPIO Other FC SCSI Disk Drive

hdisk6 Available 3A-08-01 MPIO Other FC SCSI Disk Drive

hdisk7 Available 3A-08-01 MPIO Other FC SCSI Disk Drive

使用了aix自带的驱动，会显示MPIO Other FC SCSI Disk Drive。

7、先删除掉这些hdisk设备，然后重启AIX。（疑问：应该不用重启，直接运行cfgmgr也可以把，但测试中发现确实重启才行）

3、安装后确认

1、显示一下disk的名字即可

# lsdev -Ccdisk

hdisk0 Available 11-08-00-2,0 16 Bit LVD SCSI Disk Drive

hdisk1 Available 11-08-00-4,0 16 Bit LVD SCSI Disk Drive

hdisk2 Available 34-08-01 EMC Symmetrix FCP Raid1

hdisk3 Available 34-08-01 EMC Symmetrix FCP Raid1

hdisk4 Available 34-08-01 EMC Symmetrix FCP Raid1

hdisk5 Available 34-08-01 EMC Symmetrix FCP Raid1

hdisk6 Available 34-08-01 EMC Symmetrix FCP Raid1

hdisk7 Available 34-08-01 EMC Symmetrix FCP Raid1

hdisk8 Available 34-08-01 EMC Symmetrix FCP Disk

hdisk9 Available 34-08-01 EMC Symmetrix FCP Raid1

hdisk10 Available 34-08-01 EMC Symmetrix FCP Disk

hdisk11 Available 3A-08-01 EMC Symmetrix FCP Raid1

hdisk12 Available 3A-08-01 EMC Symmetrix FCP Raid1

hdisk13 Available 3A-08-01 EMC Symmetrix FCP Raid1

hdisk14 Available 3A-08-01 EMC Symmetrix FCP Raid1

hdisk15 Available 3A-08-01 EMC Symmetrix FCP Raid1

hdisk16 Available 3A-08-01 EMC Symmetrix FCP Raid1

hdisk17 Available 3A-08-01 EMC Symmetrix FCP Raid1

第二、POWERPATH部分

准备工作

1. 获取powerpath安装文件

 到下载即可。

2. 获取EMC support matrix

 到的E-Lab按先导来操作Home >

Support >

Interoperability and

Product Lifecycle Information > E-Lab Interoperability Navigator

安装配置过程

1. 安装过程

 ftp到AIX上面，然后解压之后使用installp安装。

2. 配置过程

 powermt config 简单，一个命令即可

 powermt display dev=all 显示PATH

# powermt config

powerpath0 created

# lspv (hdiskpower*这个设备出现好像要延迟一点时间，不会马上出现，网上还看到说1天以后才出现的情况。估计是盘比较多，路径运算需要很多时间，此时连接拓扑如图1)

hdisk0 000a5e2a167bccb3 rootvg active

hdiskpower7 0002530f759b0ccc None

性能测试工作

1. 基本功能测试

1、hdisk4 已经没有PVID，尝试分配PVID，竟然成功，并且也hdiskpower设备重复

# chdev -l hdisk4 -a pv=yes

hdisk4 changed

# lspv

hdisk0 000a5e2a167bccb3 rootvg active

hdisk1 000a5e2a16a41f2a rootvg active

hdisk2 none None

hdisk3 none None

hdisk4 0002530f757a532e None

hdiskpower1 0002530f757a532e None

2、参数在全部hdiskpower*设备上面建立VG，成功；

# lsvg ttt

VOLUME GROUP: ttt VG IDENTIFIER:

0002530f00004c000000011b760be4b3

MAX PPs per PV: 1016 MAX PVs: 32

LTG size: 128 kilobyte(s) AUTO SYNC: no

HOT SPARE: no BB POLICY: relocatable

2、尝试在hdisk设备上建立vg，竟然也成功，有点奇怪了，选择hdisk4和hdisk5，慢慢观察发现，其实可以看到hdiskpower1 也已经hdiskpower2也已经连接到vg：ttt了,也就是说选hdisk或者hdiskpower都可以，最后都会反映到hdiskpower上。

2. 测试路径（path fail-over）的使用

1、在线添加一个路径（可以看到1、cfmgr 2、powermt config 3、盘全部被正常识别，并且路径已经添加,链接情况由图1变成图2，添加了path3）

3、 2FC+3FA的链接图3，识别的结果如下，按结果来看，也就是会被识别出3个路径。而不是预测的2×3=6个路径。（2个到主机，3个到磁盘，路径说很明显应该是2×3=6）

3A、尝试重启主机以后，看到全部2×3=6的路径出现了。这有点无法解析，理论上来说，AIX加盘不应该需要重启的啊。直接运行cfgmgr不行吗？

3. 测试负载均衡（load-balance）

1、连接图如3，

powerpath license active：(license已经部分屏蔽看到好多*)

从EMC盘拷贝一个2Gb的文件到rootvg上，这次取其中一个hdiskpower设备来考察，相应的路径关系如下，hdiskpower0下有6个路径到达EMC上的vol=001。从观察到的结果看，全部的路径都有读写操作。应该就可以认为是负载均衡在起作用了。

监控各自的负载情况，数据量比较大，看附件

2、模拟某个路径意外中断，观察对应用是否有什么影响：

正常拷贝：

注意到，没有任何活动的时间，反复了8次，每次2s，相当是16s的时间处于堵塞的状态，这期间其他可用的path也没有流量，这点是否说明了，多路径冗余确实冗余了，但是冗余里面出现问题还是有有轻微的影响的呢？可以仔细研究一下下面的iostat输出情况。

2A、按上例环境，enable switch port，看到情况是，path由dead状态转为active状态。但是iostat看到的情况是，虽然path已经恢复，但是很长时间内（16×2=32s）没有流量，怀疑是PowerPath的保护机制，避免path假恢复的情形下，反复启动链接，反而影响应用的使用。

3、据说无license情况下，powerpath的负载均衡功能会被disable。但实验的结果显示没有出现这种情况，而仅仅是无法再次使用powermt config 新路径而已。

# emcpreg -list

There are no license keys now registered.

# powermt config

Warning: all licenses for storage systems support are missing or expired.

做实验1同样的拷贝操作，iostat如下：

Disks: % tm_act Kbps tps Kb_read Kb_wrtn

hdisk19 7.0 1628.0 22.0 3256 0

hdisk3 4.5 814.0 16.5 1628 0

hdisk10 10.0 2998.0 33.0 5996 0

hdisk26 4.0 814.0 17.0 1628 0

hdisk33 15.5 2824.0 33.5 5648 0

hdisk42 7.0 1628.0 22.0 3256 0

hdiskpower0 35.5 10642.0 98.5 21284 0

4、powermt提供的其他功能

4、测试active/standby mode

把全部经过hba=1（display那个HW#）的全部设备设置为standby模式。

再次做上面的拷贝测试，应该是standby那个设备（hdisk3，hdisk 10，hdisk 19）应该是没有数据读写的。测试看看结果：

# powermt set mode=standby hba=1 dev=all

# powermt display dev=hdiskpower0

2、powermt display paths every=4，每4S更新显示一下path

# powermt display paths every=4

第三、Appendix：

1、# lsdev -CtSYMM* -r name |xargs -n1 rmdev –dl ，批量del全部hdisk设备。

2、# lsdev -Ctpower* -r name |xargs -n1 rmdev –dl ，del全部power设备。
