1、P550双机CPU扩容 从2路激活到4路（整理的实施步骤供参考）一、为了防止数据库数据收到影响，需要停数据库，停HACMP （或两台机器之 间切换实施），做好升级微码和升级补丁的准备二、AIX下用光盘刻录做ROOTVG系统ISO备份在没有磁带机的机器，为以防突发系统崩溃应急回退措施，需要做好系统备 份，参考如下系统ISO系统备份方法AIX操作系统版本6.1用DVD-RAM格式刻录盘直接备份rootvg并制作成可引导光盘，网上很多前辈的文章和经验都是先备份成image镜像再ftp到PC上再刻DVD盘 如下链接文章个人感觉繁琐，当前aix服务器都自带刻录DVD光驱，我这次是直 接备份刻录新P6 5

2、50的AIX服务器每台都配置有可刻录DVD光驱，我使用DVD-RAM格 式的刻录光盘直接备份（推荐使用DVD-RAM格式光盘刻录原因，公司HMC年初升 级的时候HMC上所用IBM刻录DVD光驱只能识别使用DVD-RAM刻录盘备份数据， AIX随机器附送的测试刻录光盘也是一张DVD-RAM光盘）IBM AIX P6 550随机送的测试光盘有一张DVD-RAM TEST DISC刻录盘我在 自己PC电脑上用NERO刻录光盘软件识别确认该光盘是DVD-RAM格式光盘，我测 试写入数据正常（该DVD-RAM光盘应该已经格式化过），再用NERO自带工具抹 掉测试数据，DVD-RAM光盘难买到几大网络电子

3、产品网站只在易迅网上有买 推荐选择高速亥。录盘片评估rootvg大小是否一张DVD刻录光盘足够 运行下面命令df -g -I和 lsvg -l rootvg估算rootvg大小，系统备份大小确认硬盘空间能放下备份时候 临时文件。我系统上rootvg大小没有超过4.7G，IBM 800说法若备份容量超过 4.7G 一张刻录光盘大小，备份的时候系统会自动提示换另外一张光盘，此外我查 看系统备份过程显示提示信息是先备份到硬盘临时文件，在/mkcd/mksys_image 中再写入刻录光盘 确认硬盘空间能放下备份时候临时文件。在HMC上用root账户登录，运行# smit mkdvd命令出现下图提示，

4、是否使 用已经存在的mksysb镜像，系统上之前没有做过mksysb，选择2Use an existing mksysb image?Move cursor to desired item and press Enter.1 yes2 no下面提示选择光盘格式，DVD刻录盘选择2 UDFDVD backup media format?Move cursor to desired item and press Enter.1 ISO9660 (CD format)2 UDF (Universal Disk Format)下面步骤我都是选择默认参数，网上很多朋友先备份到硬盘上image镜像再拖到

5、PC上刻录和我这次直接在AIX上刻录盘有参数差别而已#smitty mkdvdUse an existing mksysb image?xx Move cursor to desired item and press Enter.xlyes -如果首先通过smitty mksysb已经创建了 image,则选它2 no -通过mkdvd来创建image,此次选NODVD由于有两种格式，一种是ISO9660 一种是UDF格式。此次选ISO9660DVD-R or DVD-RAM Device由于不带刻录，所以此处为空，否则会失败，使用命令方式则必须指定，但需要技巧处理mksysb creatio

6、n options:Create map files?YES+Exclude files?no+Disable software packing of backup?no+Backup extended attributes?yes+File system to store mksysb image（If blank, the file system建议指定，否则会自动建立存放目录will be created for you.）File system to store DVD file structure（If blank, the file system建议指定，否则会自动建立存放目录wi

7、ll be created for you.）File system to store final DVD images /sysimag 可以创建此大小为20-30G左右的文件系统/（If blank, the file system 建议指定，否则会自动建立存放目录will be created for you.）If file systems are being created:Volume Group for created file systemsrootvg+Advanced Customization Options:Do you want the DVD tobe bootab

8、le? yes表示可以引导系统，选NO,则需要作系统光碟引导，再进行恢复。Remove final images after creating DVD?yes+Create the DVD now?NO+Install bundle file/File with list of packages to copy to DVD/Location of packages to copy to DVD+/Customization script/User supplied bosinst.data file Debug output?no+User supplied image.data file通

9、过smitty mkcd与上所填一样。2.2创建cd_image成日志mkdvd成功的日志Initializing mkcd log: /var/adm/ras/mkcd.log.Verifying command parameters.Creating image.data file.Creating mksysb image.Creating list of files to back up.Backing up 33761 files33761 of 33761 files （100%）0512-038 mksysb: Backup Completed Successfully.Popu

13、ccessful.按执行开始备份，过程显示提示信息是先备份到硬盘临时文件，在 /mkcd/mksys_image中再写入刻录光盘(硬盘上image建立很快1小时不到完 成)，硬盘备份完成写入刻录盘再把硬盘上备份image删除。备份，用的DVD-RAM刻录盘3X速度Log 在/var/adm/vas/mkcd.log 中测试该光盘是否可以引导：在空闲测试AIX上把光盘放入驱动器，shutdown -Fr关机重启服务器，在重启第一个画面（有满屏IBM出现）选择1进入SMS 菜单选择 5 Select Boot Option2 Configure Boot Device Order先选择6 Disp

15、序。附录里有前辈推荐另外一种不要机器重启来验证磁带备份系统方法，我想应该也 可以来验证光盘，可以参考。测试验证备份光盘备份内容，IBM 800建议在空闲系统上restore恢复（等 于没有说，每次全系统备份都有新机器从头到尾来restore恢复，大部分公司估 计没有这个条件）附录说明：备份的验证借鉴前辈文章：VerifyingThe ONLY method to verify that a system backup will correctly restore with no problems is to actually restore the mksysb onto another ma

16、chine. This should be done following each individual companys DISASTER RECOVERY PLAN.To minimize problems due to tape media damage, perform the following tests.WARNING:These tests ONLY verify that the tape media can be read and will NOT guarantee that a mksysb will be restored successfully.Data veri

17、ficationUsing SMITExecute the following command: smit lsmksysb A dialog box will appear.DEVICE or FILE /dev/rmt#Number of BLOCKS to read in a single input (Leave blank to use a system default) Type or select values and press enter only AFTER making the desired changes.Execute the following commands:

18、 tctl -f /dev/rmt# rewindrestore -s4 -Tvqf /dev/rmt#.1 /tmp/mksysb.log Boot verificationThe only way to verify that the mksysb tape will successfully boot is to bring the machine down and boot from the tape. No data needs to be restored.NOTE: To boot a keyless system or a system with multiprocessors

19、 in service mode, consult the models documentation or contact your AIX support representative for assistance.WARNING: Having the PROMPT field in the bosint.data file set to no causes the system to begin the mksysb restore automatically using preset values with no user intervention.If the state of PR

20、OMPT is unknown, it can be set during the boot process. After answering the prompt to select a console during the startup process, a rotating character will be seen in the lower left of the screen. As soon as this character appears, type 000 and press Enter. This will set the prompt variable to yes.

21、Check PROMPT.To check a mksysb tape to see how the PROMPT is set, run the following while in normal mode:chdev -l rmt# -a block_size=512 tctl -f /dev/rmt# rewind cd /tmprestore -s2 -xvqf /dev/rmt#.1 ./bosinst.dataCheck the PROMPT field in the control_flow stanza. Boot in SERVICE mode. If the system

22、has a key, turn it to service. If the system is keyless, consult the models documentation or contact your AIX support representative for assistance.Insert the mksysb tape into the tape drive.Execute the following command to reboot the system: shutdown -Fr The system should now boot from the mksysb t

23、ape.NOTE: Multiprocessor systems display a maintenance menu called a BUMP MENU. This is a hardware menu. For more information, consult the models documentation or contact your AIX support representative for assistance.The message press F1 or 1 for Console should appear. Press the F1 ke for a graphic

24、s display or the 1 key for an ASCII display, and press Enter. Press 1 for English, if asked.The Installation and Maintenance menu should display. The system has booted successfully.Turn the key to normal, or follow the non-key instructions for rebooting into normal mode, and REBOOT the system.三、升微码1

25、, download firmware from wed and (notice sum/version/fw file)2, get fw file to p5 machine (fw file format is *.rmp)3, unpack fw file:sum 01EL320_101_045.rpmrpm -ihv -ignoreos 01EL320_101_045.rpmnotes: p5 firmware file is 01EL320_101_045,this step auto mkdir /tmp/fwupdate.4, update firmware use updat

27、urrently booted form the temporary image.升级后有问题想回退的方式方法就是将启动由temporary side改到permanent side.操作系统起不来时有两种方式：ASMI或者control panel1) Using the control panel to switch to the other side of the service processorLearn how to use the control panel to switch to the other side of the service processor, if nece

28、ssary.You should usually be running on the Temporary side.Follow these steps to change the boot side and shut down and restart the system using the controlpanel:On the control panel, press the increment button until 02 is shown on the Function/Data display.Press Enter until the arrow () points to T

30、se steps to change the boot side and shut down and restart the system using the ASMI:Use the normal procedures to shut down the logical partitions.On the ASMI Welcome pane, specify your user ID and password, and click Log In.In the navigation area, expand Power/Restart Control and select Power On/Of

31、f System.In the Firmware boot side for the next boot field, indicate to boot to the other boot side ofthe service processor. Select Permanent or Temporary based on the information you recorded earlier.If you recorded temp or #T, select Permanent, if you recorded perm or #P, select Temporary.Choose o

The power state does not change.Click Save settings and power on/off. All selected options are saved and the system turns on or off. The power-on option

33、is available only if the system is powered off. The power-off option is only available if the system is powered on.Click Save settings and continue server firmware boot to save the selected options, and turn the server firmware on or off.
