怎樣進(jìn)行EMC存儲(chǔ)多路徑軟件配置-創(chuàng)新互聯(lián)

本篇文章為大家展示了怎樣進(jìn)行EMC存儲(chǔ)多路徑軟件配置，內(nèi)容簡(jiǎn)明扼要并且容易理解，絕對(duì)能使你眼前一亮，通過(guò)這篇文章的詳細(xì)介紹希望你能有所收獲。

員工經(jīng)過(guò)長(zhǎng)期磨合與沉淀，具備了協(xié)作精神，得以通過(guò)團(tuán)隊(duì)的力量開(kāi)發(fā)出優(yōu)質(zhì)的產(chǎn)品。成都創(chuàng)新互聯(lián)堅(jiān)持“專注、創(chuàng)新、易用”的產(chǎn)品理念，因?yàn)椤皩Ｗ⑺詫I(yè)、創(chuàng)新互聯(lián)網(wǎng)站所以易用所以簡(jiǎn)單”。公司專注于為企業(yè)提供成都網(wǎng)站建設(shè)、成都網(wǎng)站制作、微信公眾號(hào)開(kāi)發(fā)、電商網(wǎng)站開(kāi)發(fā)，微信平臺(tái)小程序開(kāi)發(fā)，軟件按需網(wǎng)站建設(shè)等一站式互聯(lián)網(wǎng)企業(yè)服務(wù)。

EMC PowerPath是用于進(jìn)行路徑選擇，冗余和負(fù)載均衡的管理軟件，相對(duì)于HP,IBM等廠商的多路徑，

EMC的優(yōu)勢(shì)在于能夠?qū)崿F(xiàn)負(fù)載均衡，而其他廠家僅支持基本故障切換。

1）安裝rpm包

先將powerpath安裝包上傳到服務(wù)器：(D:\EMC存儲(chǔ)配置\powerpath)

[root@shcrm tmp]# ls *.rpm

EMCpower.LINUX-5.3.1.00.00-111.rhel.i386.rpm

開(kāi)始安裝：

[root@shcrm tmp]# rpm -Uvh EMCpower.LINUX-5.3.1.00.00-111.rhel.x86_64.rpm

準(zhǔn)備... ########################################### [100%]

1:EMCpower.LINUX ########################################### [100%]

2）注冊(cè)

注冊(cè)PowerPathLicense：

[root@shcrm ~]# emcpreg -install

根據(jù)提示輸入PowerPathLicense

PowerPath license key: BZPV-ZB4K-BFTK-QOME-ML9O-UYFB

如果您輸入了一個(gè)有效的注冊(cè)密鑰，您將看到以下輸出：

1 Key(s) successfully added.

Key successfully installed:

如果您輸入了一個(gè)無(wú)效的注冊(cè)密鑰，屏幕上將顯示一條錯(cuò)誤消息，

提示您輸入有效的密鑰。

3）啟動(dòng)PowerPath

加載PowerPath模塊：

[root@shcrm ~]# /etc/init.d/PowerPath start

查看是否出現(xiàn)新的偽設(shè)備：

[root@shcrm ~]# fdisk -l |grep emcpower

[root@X01A19 tmp]# fdisk -l
