AIX 更换磁盘阵列
何看机器内的卡及硬盘的微码级别(microcode level)用下面命令可以得到一个SSA卡的微码级别:# lscfg -vl ssa0其中 ssa0 是此SSA卡的设备名称.输出结果中的ROS level及ID 即是微码级别(microcode level).用下面命令可以得到一个硬盘的微码级别:lscfg -vl pdiskX在RS6000系统上安装RAID适配器时，一般通过重新启动系统，AIX操作系统可以自动认到该适配器。
但是在某些情况下，系统会停留在启动RAID适配器的位置，LED面板显示：“0751-P1-I1/Q1”；若运行cfgmgr命令，报0514-407错误。
解答这时有一种可能是该RAID适配器微码版本过低，需要从IBM 网站下载最新的微码。
如何确定该RAID适配器的微码版本是否过低呢？下面以7044-270机器上的2498 PCI 4通道Ultra3 SCSI RAID适配器为例，使用下面的命令可以读到存储在适配器中的微码版本。
1）列出系统中安装的PCI RAID适配器：lsdev -C | grep scraid注意：设备名是所有已安装的PCI 4通道Ultra3 SCSI RAID适配器的名称。
适配器设备名将是scraidX, X为0，1 或其他的数字。
2）检查当前适配器的微码版本：lscfg -vl scraidX（X为系统已安装的适配器的号码。
）命令显示如下：DEVICE LOCATION DESCRIPTIONScraid0 20-58 PCI 4-Channel Ultra3 SCSI RAID AdapterPart Number.................09P1521EC Level....................0H10522Serial Number (00000001)FRU Number..................37L6892 Manufacturer................IBM000Displayable Message.........UL3RAIDDiagnostic Level (03)Device Driver Level (03)Loadable Microcode Level....4.20.01ROS Level and ID............4.00.26Device Specific.(YL)........P2-I9如果FRU Number是37L6892并且当前适配器微码版本（Loadable Microcode Level）是4.20.01，不同与适配器微码最新版本4.70.11，则需要升级微码。

在 AIX 与 FAStT 相连的环境中，FAStT 的所有设备在 AIX 中是如何定义的？解答在AIX中FAStT的相关设备是用如下AIX设备名来表现的：dar: 磁盘阵列路由器，表示与AIX相连的FAStT磁盘阵列，dac: 磁盘阵列控制器，是磁盘子系统的控制器。
大多数情况下一个FAStT中有2 个 dac 设备。
hdisk: 每一个 hdisk 设备名对应阵列中的一个LUN。
可以通过AIX命令来查看它们的属性和特点以及之间的关系。

9．如果想把这个有故障的硬盘从SCSI剔除，返回上一级菜单选择“Replace/Remove a Device Attached to an SCSI H ot Swap Enclosure Device”10, unmirrorrootvghdiskXreducevgrootvghdiskXrmdev -RdlhdiskX这时候open/stale 状态会变成open/sync换硬盘11，cfgmgr -v12, extendvgrootvg hdisk013,mirrorvg rootvg hdisk0 对于有逻辑卷的LV 拷贝空的LV 14,bosboot -ad /dev/hdisk0 刷新bootkernel15,bostboot -ad /dev/hdisk116,bootlist -m normal hdisk0 hdisk1 cd0这样换盘绝对不会出问题。
AIX下更换磁盘之更换坏盘
AIX下更换磁盘之更换坏盘选择性步骤此步骤为确保当前的hdisk0或hdisk1确为坏盘做准备，可不操作，操作只会增加安全性：1停应用2关机：#shutdown –F3停电拔出坏硬盘，看硬盘上信息FRU Number、Serial Number、Part Number是否对的起来，对应正确再一次确认了此盘是系统中对应的坏盘。
如果不是就记录下FRU Number、Serial Number、Part Number 信息，插上硬盘、开机用lscfg命令(例：lscfg -vl hdisk1)查看其它硬盘的信息。
再次确认出坏盘的正确hdisk号。
以下步骤在机器停止应用的情况下操作，应用包括：HACMP双机（smitty clstop），oracle等等。
1、坏盘为hdisk0,执行以下步骤：1)、破除镜像把HDISK0从ROOTVG中不做MIRROW：#unmirrorvg rootvg hdisk0查看物理卷#lspv这时HDISK0不在和HDISK1为MIRROR输入以下命令# lspv -l hdisk0Dumplv如果有显示上一行dumplv信息，按照以下操作：→如果现在hdisk0仍然处于激活状态，你可以简单地用“migratepv”命令把“dumplv”从hdisk0移到hdisk1：# migratepv -l dumplv hdisk0 hdisk1→如果现在hdisk0处于丢失状态或者已经坏掉，你将需要做如下操作：# lslv dumplv ---> 获得此逻辑卷的属性为你重建做准备LOGICAL VOLUME: dumplv ---VOLUME GROUP: rootvgLV IDENTIFIER: 00097c7f00004c00000000e9732a0422.16 PERMISSION: read/writeVG STATE: active/complete ---LV STATE: opened/syncdTYPE: sysdump ---WRITE VERIFY: offMAX LPs: 512 --- PP SIZE: 16 megabyte(s)COPIES: 1 -------SCHED POLICY: parallelLPs: 20 ---------PPs: 20STALE PPs: 0 --- BB POLICY: relocatableINTER-POLICY: minimum ---RELOCATABLE: yesINTRA-POLICY: middle --- UPPER BOUND: 32MOUNT POINT: N/A --------LABEL: NoneMIRROR WRITE CONSISTENCY: on/ACTIVEEACH LP COPY ON A SEPARATE PV ?: yes# sysdumpdev -Pp /dev/sysdumpnull# rmlv dumplv# mklv -t sysdump -y dumplv rootvg 20 hdisk1# sysdumpdev -Pp /dev/dumplv2)、逻辑去除磁盘把hdisk0从rootvg中去除#reducevg rootvg hdisk0在hdisk1上创建boot image#bosboot –ad /dev/hdisk1改变启动设备的顺序#bootlist –m normal hdisk1 cd0删除HDISK0#rmdev –dl hdisk0#lspv#lscfg –vl hdisk0以上2条命令不会显示hdisk0的相关信息，表示已删除hdisk03)、移出热插拔磁盘1. 当前系统登录用户身份应是root，如果不是以root用户身份登录进入系统；2. 在命令行输入“ smit”；3. 选择 System Storage Management (Physical and Logical Storage)；4. 选择 Removable Disk Management；5. 选择 Remove a Disk；6. 从屏幕列示中选择要移出的硬盘hdisk0然后按下回车键；7. 按照屏幕上的指导来移出硬盘；8. 当你被询问“Are you sure?”, 按下回车键. 你选择的硬盘的电源显示灯将保持亮的状态；9. 物理上移出硬盘；10. 按下 F10退出smit菜单.4)、加回热插拔磁盘1. 物理安装新硬盘到硬盘槽里；2. 当前系统登录用户身份应是root，如果不是以root用户身份登录进入系统；3. 在命令行输入“ smit”；4. 选择 Devices.5. 选择 Install/Configure Devices Added After IPL 并且按下回车键.5)、重新镜像rootvg卷组下面的步骤认为用户有一个包含hdisk1的rootvg卷组并且准备镜像rootvg到一个新磁盘：hdisk0.1.把hdisk0加进rootvg卷组：#extendvg rootvg hdisk02.关掉rootvg的 QUORUM功能:#chvg -Qn rootvg3.镜像rootvg#mirrorvg -c 2 rootvg hdisk04.重新生成 boot image#bosboot -ad /dev/hdisk05.更新bootlist#bootlist -m normal hdisk0 hdisk1 cd06.重起系统#shutdown -Fr系统正常运行，完毕。

AIX磁盘更换
情景 1如果要替换的磁盘已做了镜像，推荐如下步骤：1. 删除该磁盘上所有逻辑卷的复件，使用 rmlvcopy 命令或 unmirrorvg 命令。
2. 从卷组中删除该磁盘，使用 reducevg 命令。
3. 使用 rmdev 命令删除该磁盘定义。
4. 物理移除该磁盘。
如果磁盘不是可热交换的（hot-swappable），可能要求重启系统。
5. 使备用的磁盘可用。
如果磁盘是可热交换的（hot-swappble），可运行 cfgmgr；否则，需要重启系统。
6. 把新加的磁盘放入卷组，使用 extendvg 命令。
7. 重建并同步所有逻辑卷的复件，使用 mklvcopy 命令或 mirrorvg 命令。

5．系统性能检查：a) CPU性能：使用Vmstat, topas来检查b) 内存使用情况：也是使用topas, vmstat来检查c) 检查IO平衡使用情况：使用iostat来检查d) 交换空间使用情况：使用lsps –a来检查6． Mail检查7． Diag 一个月一次补充两点：1。
硬件检查，检查各指示灯状态和各物理设备的可用情况。
2。
进程检查，检查是或有死进程。
用who -d 查出一些死进程！AIX日常指令和常用操作一：开机登录在开机之前，先检查电源是否插好；然后，按下前面板上白色电源开关后，主机会进入硬件自检和引导阶段；此时，前面板上的液晶会有代码跳动，每一个代码表示自检或引导的不同阶段，最后在引导结束时，前面板液晶上的代码消失，彩显或终端上有显示，进入系统初始化和登录提示。
如果主机停在某一代码上，引导不下去(大于半小时)，说明系统可能有故障，请与IPACS 联系，并把代码一起报给我们。
二：关机1)关闭应用程序2)HACMP软件，先用smit clstop关闭HACMP。
3)命令行打“shutdown -F”进关机，显示器上出现“Halt Completed”可按下前面板上白色电源开关，关电源。
如果需要关机后重新引导，打“shutdown -Fr”命令。

This would apply toenvironments that use HACMP, RVSD, or any other managementsoftware. Refer to the documentation for that product for correct disk replacement procedures. The SSA User's Guide explains the procedures for changing disks in a RAID or hot swap environment.It is available for download at:/support/docview.wss?rs=505&uid=ssg1S10023482.The disk is in rootvg and the disk contains any one of the followinglogical volumes, which are not mirrored:hd2, hd3, hd4, hd6, hd9var, hd8In this case, you would need to replace the disk and restore froma system backup specifying the correct disks to restore.3.The system is a /usr, dataless, or diskless client.This document applies to AIX Versions 4.3.3 and 5L.Please read the entire document before proceeding and ensure all relevant fixes mentioned in this document or otherwise are installed prior to using these procedures.Removing a physical volume from a volume groupThe basic steps to replacing a disk drive are as follows:1.Deallocate all the physical partitions associated with thephysical volume in the associated volume group.2.Remove the physical volume from the volume group.3.Remove the definition for the disk from the device configurationdatabase.These steps are outlined in more detail in subsequent sections.If there is just one disk in the volume group, proceed to the next section, "How to proceed if the volume group has just one disk." Otherwise, proceed to the section entitled "Deallocating physical partitions from the disk."How to proceed if the volume group has just one diskIf the drive to be replaced is the only drive in the volume group, then remove the volume group definition with:exportvg <VGname>At this point, remove the disk definition using the rmdev command. Details are included in the section "Removing the disk definition from the system" in this document.Checking to see what quorum is set toIf your volume group is mirrored, you could have disabled quorum. The purpose of quorum is explained in the IBM Redbook: LVM: Introduction and Concepts. Here is an excerpt:A quorum is a vote of the number of Volume Group Descriptor Areas and Volume Group Status Areas (VGDA/VGSA) that are active. A quorum ensures data integrity in the event of a disk failure. Each physical disk in a volume group has at least one VGDA/VGSA. When a volume group is created onto a single disk, it initially has two VGDA/VGSA areas residing on the disk. If a volume group consists of two disks, one disk still has two VGDA/VGSA areas, but the other disk has one VGDA/VGSA. When the volume group is made up of three or more disks, then each disk is allocated one VGDA/VGSA.A quorum is lost when enough disks and their VGDA/VGSA areas are unreachable so that a 51% majority of VGDA/VGSA areas no longer exists. In a two-disk volume group, if the disk with only one VGDA/VGSA is lost, a quorum still exists because two of the three VGDA/VGSA areas still are reachable. If the disk with two VGDA/VGSA areas is lost, this statement is no longer true. The more disks that make up a volume group, the lower the chances of quorum being lost when one disk fails.lsvg testvg --> check to see if Quorum is set to 1VOLUME GROUP: testvg VG IDENTIFIER:00097c7f00004c00000000f4a163bc7bVG STATE: active PP SIZE: 16 megabyte(s)VG PERMISSION: read/write TOTAL PPs: 1084 (17344 megabytes)MAX LVs: 256 FREE PPs: 998 (15968 megabytes)LVs: 12 USED PPs: 86 (1376 megabytes)OPEN LVs: 9 QUORUM: 1TOTAL PVs: 2 VG DESCRIPTORS: 3STALE PVs: 1 STALE PPs: 1ACTIVE PVs: 2 AUTO ON: yesMAX PPs per PV: 2032 MAX PVs: 16If replacing the disk drive immediately, then you may not have to turn quorum back on. The mirrorvg command automatically turns quorum off and the unmirrorvg command automatically turns quorum on. If you are dealing with rootvg, the only way to have a change in quorum take effect, is to reboot. If this is a non-rootvg volume group, quorum can be changed by varyingoff the volume group and then varying it back on. To change quorum from the command line, run the following:chvg -Q n vgname --> turns quorum offchvg -Q y vgname --> turns quorum onIn order to varyoff a volume group, unmount all filesystems and make sure all logical volumes are in a closed state. Enter:lsvg -l testvgLV NAME TYPE LPs PPs PVs LV STATE MOUNT POINTtestlv jfs2 1 1 1 closed/sync'd /testfsloglv00 jfs2log 1 1 1 closed/sync'd N/AOnce all the logical volumes are closed, run the following:varyoffvg vgnamevaryonvg vgnameThe new quorum change will be in effect.Deallocating physical partitions from the diskEvery physical partition (PP) on the disk allocated to any logical volume (LV), including file systems or paging spaces, must be deallocated, either by moving the contents of those PPs to another disk or by removing them.To determine what logical volumes have PPs allocated to that disk, run: lspv -l <hdisk#>If the hdisk name no longer exists, and the disk is identifiable only by its 16-digit PVID (you might see this from the output of lsvg -p <VGname>), substitute the PVID for the disk name. For example:lspv -l 0123456789abcdefYou may receive the following error:0516-320 : Physical volume 00001165a97b10c6 is not assigned toa volume group.If so, run the following command:putlvodm -p `getlvodm -v <VGname>` <PVID>VGname refers to your volume group, PVID refers to the 16-digit physical volume identifier, and the characters around the getlvodm command are grave marks, the backward single quote mark. The lspv -l <PVID>command should now run successfully.If another disk in the volume group has space to contain the partitions on this disk, and the disk to be replaced has not failed, the migratepv command may be used to move the used PPs on this disk. See the man page for the migratepv command on the steps to do this.If the partitions cannot be migrated, they must be removed. The output of the lspv -l <hdisk#>, or lspv -l <PVID>, command indicates what logical volumes will be affected. Run the following command on each LV: lslv <LVname>The COPIES field shows if the LV is mirrored. If so, remove the failed copy with:rmlvcopy <LVname> 1 <hdisk#>hdisk#refers to all the disks in the copy that contain the failed disk.A list of drives can be specified with a space between each. Use the lslv -m <LVname> command to see what other disks may need to be listed in the rmlvcopy command. If the disk PVID was previously used with the lspv command, specify that PVID in the list of disks given to the rmlvcopy command. At AIX Version 4.2.1 or higher, the unmirrorvg command may be used in lieu of the rmlvcopy command. See the man pages for rmlvcopy and unmirrorvg, or other documentation, for additional information.If the LV is not mirrored, the entire logical volume must be removed, even if just one physical partition resides on the drive to be replaced and cannot be migrated to another disk. If the unmirrored LV is a JFS file system, unmount the file system and remove it. Enter:umount /<fsname>rmfs /<fsname>If the unmirrored logical volume is a paging space, see if it is active. Enter:lsps -aIf it is active, set it to be inactive on the next reboot. Enter:chps -a n <LVname>After you reboot, remove it by entering:rmps <LVname>Remove any other unmirrored logical volume with the following command: rmlv <LVname>NOTE:If the LV is serving as a dump device, the dump pointer must first be reassigned. The same is true if the LV was mirrored and the copy is being removed. Check the dump pointers by entering:sysdumpdev -lReassign the dump pointers. Enter:sysdumpdev -Pp /dev/sysdumpnull (for the primary device)sysdumpdev -Ps /dev/sysdumpnull (for the secondary device)The pointers can be reassigned to the appropriate logical volume after it is recreated.Deleting the disk from the volume groupUsing either the PVID or the hdisk name, depending on which was used when running lspv -l <hdisk#> in the preceding discussion, run one of the following:reducevg -f <VGname> <hdisk#>reducevg -f <VGname> <PVID>If you used the PVID value and if the reducevg command complains that the PVID is not in the device configuration database, run the following command to see if the disk was indeed successfullyremoved:lsvg -p <VGname>If the PVID or disk is not listed at this point, then ignore the errors from the reducevg command.Removing the disk definition from the systemRemove the hdisk. Enter:rmdev -dl <hdisk#>If the disk was an SSA disk, delete the pdisk. Enter:rmdev -dl <pdisk#>If the disk was an SSA disk, determine which pdisk numbercorresponds to the hdisk. The easiest way to do this is by using the ssaxlate commands. Enter the following:ssaxlate -l hdisk# --> shows the pdisk#(s) definitionssaxlate -l pdisk# --> shows the hdisk# definitionAnother way to do this is with the following commands:lsdev -Cc disk -F name' 'connwherelsdev -Cc pdisk -F name' 'connwhereSee which SSA disk serial number coincides with the hdisk to remove.If the hdisk does not appear, or if the user has been working witha PVID value up to this point, the pdisk whose serial number doesnot coincide with any of the hdisks is likely to be the disk to remove. Other SSA commands might provide additional information.Consult the SSA documentation.If you have been working with a PVID value rather than with an hdisk name, ensure that the PVID is removed from the ODM with thefollowing command. The 32-digit value supplied consists of the PVID plus 16 zeros. For example:odmdelete -q value=0073659c2c6d26f10000000000000000 -o CuAtTo physically remove the hard disk, consult the documentation for that device, or the hardware service organization for the vendor.Adding a new drive to an existing volume groupOnce the new drive has been configured, ensure that a proper PVID has been written to the drive by running:chdev -l <hdisk#> -a pv=clearchdev -l<hdisk#> -a pv=yesNOTE: On SSA drives, the first chdev command may be omitted.Add the drive to the volume group with:extendvg VGname hdisk#You can also use the mkvg command to create a new volume group on the new drive.New logical volumes, paging spaces, file systems, or logicalvolume copies can be re-added with the mklv, mkps, crfs, mklvcopy, or mirrorvg commands, respectively, or by using SMIT.Recommended fixesNOTE:In AIX Versions 4 and 5, use the command instfix -ik <APAR> to determine if a particular fix is installed.There are numerous fixes corresponding to mirroring, pvids, and synching of volume groups in AIX. It is recommended that the customer be at the latest maintenance level (ML) for their different environments. The latest fixes/ML's can be downloaded from "Quick links to AIX fixes"(/servers/eserver/support/unixservers/aixfix es.html).In addition, the filesets that correspond to mirroring and synchronizations of disk drives are bos.rte.lvm and bos.rte.filesystem.。
