AIX环境下安装、卸载PowerPath

AIX环境下安装PowerPath

安装软件

1 将powerpath ODM上传到AIX主机下的/tmp/emc目录下，然后用uncompres命令将包文件解开；

#uncompress /tmp/powerpath/EMC.AIX.5.3.0.1.tar.Z #tar –xvf EMC.AIX.5.3.0.1.tar

2 smitty 命令选择安装目录，安装AIX ODM #smitty installp

3 将powerpath4.5.3 for AIX上传到AIX主机下的/tmp/emc/powerpath目录下，然后用gunzip命令将包文件解开；

#gunzip /tmp/emc/powerpath/EMCpower.AIX.4.5.3.patch.tar.gz #tar –xvf EMCpower.AIX.4.5.3.tar

4 smitty 命令选择安装目录，安装powerpath软件 #smitty installp

5.确认powerpath是否安装成功 #lslpp -l|grep power 6.注册PowerPath软件 #emcpreg –install

7.#cfgmgr -v //确保系统认到新的hdiskpower and hdisk

#powermt config //执行powermt命令识别POWERPATH设备

#powermt display dev=all //检查POWERPATH设备识别情况,policy为SymmOpt #powermt save //保存POWERPATH配置

卸载PowerPath

1 lslpp -l|grep power //检查powerpath安装的版本 2 smitty remove

3 选择要卸载的powerpath，Esc+7选择 4 回车确定卸载

5 lslpp -l|grep power //检查是否卸载成功

1 安装PowerPath的集群AIX平台使用EMC Symmetrix磁盘注意事项

1.1 在HACMP中设置emcpowerreset以及break reserves in parallel =true

为保证HACMP能够顺利切换并且最大限度地加快切换速度, 需要在HACMP配置中遵循以下指导:

For HACMP 5.1 and higher (SMIT)

1. Enter into the SMIT fastpath for HACMP \ 2. Select Extended Configuration.

3. Select Extended Resource Configuration.

4. Select HACMP Extended Resources Configuration. 5. Select Configure Custom Disk Methods. 6. Select Add Custom Disk Methods.

7. The following fields are available, enter as follows;

For IBM Fibre Channel configurations with PowerPath 3.0.3 and higher: Disk Type (PdDvLn field from CuDv) = disk/pseudo/power Method to identify ghost disks = SCSI3

Method to determine if a reserve is held = SCSI_TUR

Method to break a reserve = /usr/lpp/EMC/Symmetrix/bin/emcpowerreset Break reserves in parallel = true

Method to make the disk available = MKDEV

8. Configure the same custom disk processing method on each node in the cluster and synchronize the cluster resources. The cluster verification process ensures that the method that you configured exists and is executable on all nodes. The synchronization process ensures that the ODM entries are the same on all nodes, but will not synchronize the methods named in the ODM entries.

Note To help insure emcpowerreset is installed and configured correctly, go to \and enter the command \HACMPdisktype\ If installed correctly you should see \ See example below: HACMPdisktype:

PdDvLn = \ ghostdisks = \ checkres = \

breakres = \emcpowerreset\ parallel = \true\

makedev = \ reserved1 = \ reserved2 = \

reserved3 = \

In addition, after a failover, you can look at the \appears for the FC Path and/or hdisk entry. See example below: Clar_Cascade_1:cl_disk_available[13] ckres_rc=2 Clar_Cascade_1:cl_disk_available[13] [[ 2 != 0 ]] Clar_Cascade_1:cl_disk_available[29]

/usr/lpp/EMC/CLARiiON/bin/emcpowerreset fscsi1 hdiskpower38 Clar_Cascade_1:cl_disk_available[1228] echo

Clar_Cascade_1,Clar_Cascade_1 Clar_Cascade_1:cl_disk_available[1228] read vg

注: 从HACMP V5.4开始, 无需配置使用“emcpowerreset”

1.2 LV Striping

EMC强烈建议在条件许可的情况下, 在主机层面进行LV Striping设置以提高IO性能. 通常Striping宽度为4的倍数, 深度取决于客户应用的IO Size, 一般可取32k.

Clar_Cascade_1,Clar_Cascade_1 Clar_Cascade_1:cl_disk_available[1228] read vg

注: 从HACMP V5.4开始, 无需配置使用“emcpowerreset”

2.2 在HACMP+PowerPath环境中设置cfgscsi_id以提高HACMP启动和切换速度

注1：在Symmetrix环境中不需要设置此脚本，而在Clariion环境中需要设置此脚本。安装时，必须同时安装”emcpowerreset”。 注2：“cfgscsi_id”取代了以前的”set_scsi_id”，某些用户可能已经安装了”set_scsi_id”，这种情况下，不需要重新安装。

Procedure to configure into HACMP:

After going to Powerlink to download \and make it executable. Use the procedure below, on every node in the cluster, to add the \
