CISCO IOS XR軟件補丁（SMU）安裝操作

1、首先，將SMU安裝包上傳到IOS XR路由器本地磁盤，通過查看指定磁盤目錄，可以看到將要安裝的SMU安裝包，如下所示：

RP/0/RP0/CPU0:MC-LCC0-40G#dir harddisk:/smu  

Thu Jan 15 08:07:22.089 UTC

Directory of harddisk:/smu

59041       -rwx  368158     Wed Jan 14 07:09:20 2015 hfr-px-5.1.4.CSCur74848.pie

2014288     -rwx  1393642    Wed Jan 14 07:10:07 2015 hfr-px-5.1.4.CSCur39971.pie

2014287     -rwx  6129366    Wed Jan 14 07:10:25 2015 hfr-px-5.1.4.CSCuq95241.pie

15426650112 bytes total (12678681088 bytes free)

2、加載SMU安裝包，加載完成后，SMU安裝包會解壓到disk0磁盤（相當于windows操作系統C盤），輸出信息會提示disk0下SMU安裝包路徑，如下紅色字體所示：

RP/0/RP0/CPU0:MC-LCC0-40G(admin)#install addharddisk:/smu/hfr-px-5.1.4.CSCur74848.pie synchronous

Thu Jan 15 08:07:50.335 UTC

Install operation 38 '(admin) install add/harddisk:/smu/hfr-px-5.1.4.CSCur74848.pie synchronous' started by user 'cisco'via CLI at 08:07:50 UTC Thu Jan 15 2015.

Info:     The followingpackage is now available to be activated:

Info:     

Info:         disk0:hfr-px-5.1.4.CSCur74848-1.0.0

Info:     

Info:     The package can beactivated across the entire router.

Info:     

Install operation 38 completed successfully at 08:07:56 UTC Thu Jan15 2015.

3、SMU安裝包加載成功后，通過命令可以在未激活安裝包列表中查看到其信息，如下所示：

RP/0/RP0/CPU0:MC-LCC0-40G(admin)#sho install summary

    disk0:hfr-diags-px-5.1.4

    No packages.

4、激活SMU安裝包，注意選擇SMU安裝包解壓后的路徑，應該選擇disk0磁盤下的，命令和輸出如下所示；如果有多個SMU安裝包進行激活，可以在一條命令中同時列出多個SMU安裝包的信息，而不需要通過多條命令來執行，如果有多個SMU安裝包激活時需要重啟系統的，則可以避免多次重啟系統；

RP/0/RP0/CPU0:MC-LCC0-40G(admin)# install activate disk0:hfr-px-5.1.4.CSCur74848-1.0.0synchronous

Thu Jan 15 08:10:02.352 UTC

5、SMU安裝包激活成功后，可以看到該SMU安裝包在激活安裝包列表中，如下所示：

6、如果是需要重啟的SMU安裝包，SMU安裝包成功激活后，IOSXR系統自動進行重啟，重啟完成后，還需要執行commit，否則，下次重啟該SMU可能失效；而且commit建議在重啟完成后執行，如果SMU安裝包后系統異常，可以通過重啟系統來進行回退操作，如果重啟前先執行了commit操作，則需要執行去激活SMU安裝包。commit操作如下所示：

RP/0/RP0/CPU0:MC-LCC0-40G(admin)#install commit

7、注意：在執行SMU操作的時候，要確保各板卡和硬件模塊狀態正常，否則無法執行SMU；例如，有一塊板卡故障，則需要先手動關閉板卡，再執行SMU。
