Veritas Volume Manager(VxVM)-vxassist命令手册

vxassist是VxVM中非常重要的一个工具,使用非常频繁,我这里给出一个命令手册,并作了一些简单的翻译和注释,仅供参考.General1. Creating a Volume1.1 Creating a Concatenated V olume1.2 Creating a Striped V olume1.3 Creating a RAID-5 V olume2. Extending a Volume2.1 Extending a volume up to certain length2.2 Extending by a Given Length3. Shrinking a V olume3.1 Shrinking to a Given Length3.2 Shrinking by a Given Length4. Removing a Volume5. Mirroring a V olume5.1 Creating & Mirroring a New Volume5.2 Mirroring an Existing V olume5.3 Mirroring All Volumes6.Removing a Mirror7.Adding a RAID-5 Log8.Adding a DRL Log9.Removing a RAID-5 Log10.Preparing a Volume for Online Backup11.Displaying Volume Configuration InformationGeneralvxassist工具是VxVM中用于进行卷管理的工具,可以用于创建卷、增加镜像、扩展或者收缩存在的卷等,是非常重要的一个工具.The vxassist utility in Veritas Volume Manager is used to create volumes, add mirrors and logs to existing volumes, extend and shrink existing volumes, provides for the migration of data from a specified set of disks, and provides facilities for the on-line backup of existing volumes. vxassist在创建卷组时,如果不指定,缺省的会把卷分配给rootdg(note:在VxVM4.0中rootdg 不再必须,但是你可以指定一个default dg具有类似的功能).vxassist的缺省单位是blocks,但是你可以指定K 或M 或G 为单位,这都是合法的.The default behavior of vxassist is to create volumes in the rootdg diskgroup if diskgroup is not specified . The default length is taken as number of blocks but this can be specified in Kilobytes or Megabytes or Gigabytes.vxassist command syntax :vxassist <option> <Keyword> volume_name [attributes]Commonly used options are given below (See man vxassist for complete list of supported options) -g for specifying diskgroups -b for background operation -d file containing defaults for vxassist if not specified /etc/default/vxassist is used Keywords used are make , mirror , move , growto ,growby ,shrintto ,shirnkby ,snapstart , snapshot ,snapwait Attributes specify volumes layout disks controllar to include exclude etcDevice Nodes :Default rootdg disk group. Block Device Node /dev/vx/dsk/volume_name Raw Device Node /dev/vx/rdsk/volume_name Other DiskGroups Block Device Node /dev/vx/dsk/diskgroup_name/volume_name Raw Device Node /dev/vx/rdsk/diskgroup_name/volume_name_______________________________________1. Creating a Volume :1.1 Creating a Concatenated Volume缺省的,vxassist把一个卷组里的所有磁盘统一看待,如果创建的volume大于单个磁盘,那么空间分配自动的跨越磁盘.By default, vxassist creates a concatenated volume using the space available on a disk or on the number of disks in a diskgroup if the volume size specified is more then the one available on a single disk.Disks can be specified from a diskgroup for a volume group but if not mentioned available disks are selected by the volume manager.Command syntax :· vxassist make volume_name volume_lengthTo create a new volume appvol of 100 MB in the default disk group rootdg with available disks:· #vxassist make appvol 100mTo create the volume appvol of 100MB on disk03· #vxassist make appvol 100m disk031.2 Creating a Striped VolumeA striped volume contains at least one plex that consists of two or more subdisks located on two or more physical disks.Command Syntax :· vxassist make volume_name length layout=stripeTo create a striped volume appvol2 with the default stripe unit size on the default number of disks· #vxassist make appvol2 100m layout=stripeTo create a striped volume appvol2 100MB striped volume on three specific disks.· #vxassist make appvol2 100m layout=stripe disk04 disk05 disk061.3 Creating a RAID-5 VolumeA RAID-5 volume contains a RAID-5 plex that consists of two or more subdisks located on two or more physical disks. Only one RAID-5 plex can exist per volume. A RAID-5 volume may also contain one or more RAID-5 log plexes, which are used to log information about data and parity being written to the volume.Command Syntax :· vxassist make volume_name length layout=raid5To create the RAID-5 volume appvol4 with the default stripe unit size on the default number of disks with RAID-5 log,· #vxassist make appvol4 100m layout=raid5.2. Extending a Volume--扩展一个建好的VolumeCaution : If you plan to use volume size change (grow or shrink ) on a volume with data make sure you have the good backup of the volume available before carrying out such operation .2.1 Extending a volume up to certain lengthCommand syntax· vxassist growto volume_name lengthTo extend vol3 upto 8000 sectors, type:--例如,扩展vol3到8000个扇区· #vxassist growto vol3 8000Note:这里可以指定大小,例如:vxassist growto redo101 100M如果使用的是非缺省DG,还需要指定磁盘组:vxassist -g oradg growto redo101 100M2.2 Extending by a Given LengthCommand Syntax· vxassist growby volume_name lengthTo extend volapp by 1000 sectors, type:· #vxassist growby volapp 10003. Shrinking a VolumeCaution - Do not shrink a volume below the size of the file system. If you have a VxFS file system, you can shrink the file system and then shrink the volume. If you do not shrink the file system first, you risk unrecoverable data loss.Always make sure you have a good backup of the data volume to be shirnked.3.1 Shrinking to a Given LengthShrink a volume to a specific length as follows:· vxassist shrinkto volume_name lengthMake sure you do not shrink the volume below the current size of the file system or database using the volume. This command can be safely used on empty volumes.To shrink volcat to 1300 sectors, type:· #vxassist shrinkto volcat 13003.2 Shrinking by a Given LengthShrink a volume by a specific length as follows:· vxassist shrinkby volume_name lengthTo shrink volcat by 8000 sectors, type:· #vxassist shrinkby volapp2 80004. Removing a VolumeRemoving a volume requires removing all references to the volumes to be removed like unmounting the volume if mounted and removing its reference from /etc/vfstab .如果你需要remove一个volume,那么首先你需要stop这个卷组,停止其上的所有活动事务.An active volume has to be stopped first to stop all the activities to the volume only then it can be removed.Stopping Volume :Command Syntax· vxvol stop volume_nameTo stop appvol1· #vxvol stop appvol1Removing VolumeCommand Syntax· vxedit -rf rm volume_nameTo remove the volume appvol1· #vxedit -rf rm appvol115. Mirroring a VolumeMirroring allow data to be written simultaneously to two disks so that in case of failure of one disk data is available from the other mirrored disk. Boot disks can be mirriored to provide alternate booting disk .5.1 Creating & Mirroring a New VolumeCommand Syntax :· vxassist make volume_name length layout=mirrorTo create the mirrored volume, appvol22 of 100mb· #vxassist make appvol22 100m layout=mirrorTo create a volume with Dirty Region Logging enabled· #vxassist make volume_name length layout=mirror,log5.2 Mirroring an Existing VolumeCommand syntax· vxassist mirror volume_nameCreating a mirror of volume vol44:· #vxassist mirror vol445.3 Mirroring All VolumesTo mirror all existing volumes to available disk space· /etc/vx/bin/vxmirror -a6. Removing a MirrorRemoving a mirror involves first dissociating the plex from its volume and then removing the plex and any associated subdisks completely.The last valid mirror plex associated with a volume cannot be removed.Dissociate and remove the plex from its volume as follows:· vxplex -o rm dis plex_namevxprint -h shows the volume and associated plexes :Disk group: rootdg TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0 v volm fsgen ENABLED 10240 - ACTIVE - - pl volm-01 volm ENABLED 10240 - ACTIVE - - sd disk01-02 volm-01 - 10240 0 - - - pl volm-02 volm ENABLED 10240 - ACTIVE - - sd disk02-03 volm-02 - 10240 0 - - -To disassociate and remove volmir-02 from volmir, type:· #vxplex -o rm dis volm-02The output of vxprint -h for volm now shows volume volm with only one plex::Disk group: rootdg TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0 v volm fsgen ENABLED 10240 - ACTIVE - - pl volm-01 volmir ENABLED 10240 - ACTIVE - - sd disk01-02 volmir-01 - 10240 0 - - -7. Adding a RAID-5 LogA RAID-5 log maintains a copy of the data and parity being written to the volume at any given time. If a system failure occurs, VxVM can replay the RAID-5 log to resynchronize the volume. This copies the data and parity that was being written at the time of failure from the log to the appropriate areas of the RAID-5 volume.RAID-5 log plexes are used to log information about data and parity being written to the raid volume. A log plex is created for the volume by default when a raid volume is created but additional ones can be added by following command .· vxassist addlog name_of_raid5_vol8. Adding a DRL LogDirty region logging (DRL) is used with mirrored volume layouts. DRL keeps track of the regions that have changed due to I/O writes to a mirrored volume. Prior to every write, a bitmap is written to a log to record the area of the disk that is being changed. In case of system failure, DRL uses this information to recover only the portions of the volume that need to be recovered.To put Dirty Region Logging into effect for a volume, a log subdisk must be added to that volume and the volume must be mirrored. Only one log subdisk can exist per plex.The following example creates a log for the mirrored volume vol03:· #vxassist addlog vol03When vxassist is used to add a log subdisk to a volume, a log plex is also created to contain the log subdisk, by default.Once created, the plex containing a log subdisk can be treated as a regular plex. Data subdisks can be added to the log plex. The log plex and log subdisk can be removed using the same procedures used to remove ordinary plexes and subdisks.9. Removing a RAID-5 LogRemoving a RAID-5 log involves first dissociating the log from its volume and then removing the log and any associated subdisks completely.Dissociate the log from its volume as follows:· #vxplex -o rm dis plex_nameTo identify the log plex, use the command:· vxprint -ht raid5_volume_nameTo disassociate the log plex volrd-02 from volrd, type:· #vxplex -o rm dis volrd-02The output of vxprint -h for volrd now shows:Disk group: rootdg TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0 v volrd raid5 ENABLED 32 - ACTIVE - - pl volrd-01 volrd ENABLED 32 - ACTIVE - - sd disk01-02 volrd-01 - 32 0 - - - sd disk02-03 volrd-01 - 32 0 - - -10. Preparing a Volume for Online BackupVolume manager provides an easy way to take backup of the online data by creating an offline snapshot mirror of the volume .The vxassist snapstart operation creates a write-only backup mirror, which is attached to and synchronized with the volume to be backed up and later detached and made offline by vxassist snapshot command . The snapshot volume can be used by backup utilities while the original volume continues to be available for applications and users.The volume backup method described here does not apply to RAID-5 volumes.Backing up a volume with vxassist involves the following procedureCreate a snapshot mirrorsnapstart starts creating a online snapshot mirror of the volume using the available disk space . The snapshot is completed with vxassist snapshot command when offline snapshot volume is created with a userdefined name .Command Syntax:vxassist snapstart volume_nameTo create a snapshot mirror of a volume called vol8, type#vxassist snapstart vol8Create a snapshot volumeCommand Syntaxvxassist snapshot volume_name new_volume_nameTo create a snapshot volume of vol8, type:#vxassist snapshot vol8 snapvol8You can now back up the snapshot volume by whatever means you prefer. To avoid wasting space, you can then remove the snapshot volume, which occupies as much space as the original volume11 Displaying Volume Configuration InformationThe vxprint command can be used to display information about how a volume is configured.Display the volume, mirror, and subdisk record information for all volumes as follows:#vxprint -htclass="style25 style31"Disk group: rootdgDG NAME NCONFIG NLOG MINORS GROUP-IDDM NAME DEVICE TYPE PRIVLEN PUBLEN STATE V NAME USETYPE KSTATE STATE LENGTH READPOL PREFPLEXPL NAME VOLUME KSTATE STATE LENGTH LAYOUT NCOL/WID MODESD NAME PLEX DISK DISKOFFS LENGTH [COL/]OFF DEVICE MODEdg rootdg 759096729.1025.tweetydm disk10 c1t0d0s2 sliced 559 1044400 -dm disk20 c2t0d0s2 sliced 559 1044400 -v pubs fsgen ENABLED ACTIVE 2288 SELECT -pl pubs-01 pubs ENABLED ACTIVE 2288 CONCAT - RWsd disk10-01 pubs-01 disk10 0 2288 0 c0t0d0 ENAv vol8 fsgen ENABLED ACTIVE 20480 SELECT -pl vol8-01 vol8 ENABLED ACTIVE 20480 CONCAT - RWsd disk10-02 vol8-0 disk10 2288 20480 0 c0t1d0 ENAwhere dg is a disk group, dm is a disk, v is a volume, pl is a plex, and sd is a subdisk.

VERITAS9.0实用操作手册（经验版）Kernel ()目录●安装指南一、服务器端的安装二、服务器端的配置二、客户端的安装三、安装过程中的常见问题●应用指南一、WIN2000系统的备份/恢复1、提交备份作业1、恢复到同一台计算机上2、异机的恢复（恢复到到不同的计算机上）●SQL数据库服务器的备份与恢复1、仅仅数据库损坏，手工恢复系统库以及用户数据库2、灾难恢复SQL数据库3、重定向恢复数据库安装指南说明：本操作指南中使用的VRITAS的版本号为9.1.4691,是目前最新版的VERITAS EXEC版本。

本操作手册仅仅是一个快速入门手册，更详细的操作请参考《Veritas Exec用户参考手册》对于VRITAS9.0的安装有两种方式：升级安装和全新安装。

升级安装是指企业中原先在使用VRITAS8.6产品，那么你得到新的9.0产品时一般是VERITAS 公司的升级光盘，这个升级光盘是不能够全新安装的，只能从V8.6版本上升级到9.0。

在光盘的协议中会提供一组升级用的序列号。

这样就麻烦一些，要先安装V8.6然后再升级到9.0。

关键就是序列号的问题，因为只有升级序列号，如果有全新的序列号，那么就可以全新安装的。

因为在从V8.6升级到V9.0的时候，VERITAS会生成一组新的安装序列号。

因此只要把安装后的SN记录下来，就可以把升级安装变成全新的完全安装了。

全新安装问题会少很多,但是客户机必须要把原来的V8.6组件全部卸载掉，然后再安装V9.0组件。

安装前客户端和服务器端有几个前提要注意一下：1．MDAC的版本也有要求，要2.7以上，WINDOWS 2000 SERVER中的是2.6 看MDAC的版本号在注册表的：\HKEY_LOCAL_MACHINE\SOFTWARE\ Microsoft\DataAccess中可以看到。

2．介质服务器端需要的安装SQL2000客户端（注意是客户端，不是服务器端），主要是为了备份SQL2000 SERVER需要。

并且要安装SQL 2000 SP3：3．介质服务器WIN2000 SERVER系统要安装最新的SERVICE PACK，目前最新的是SP44．如果介质服务器和目标服务器是工作组模式，那么介质服务器和目标服务器上都需要建立备份的同名账号，来解决网络访问备份的权限问题，并且需要将这个同名账号加入管理员组（其实应该在“备份操作员组”就可以了，但为了减少麻烦，索性就加入管理员组），然后用这个同名账号作为默认账号登陆介质服务器。

一定要检查一下这个同名账号是否对目标服务器的所有盘允许访问了，最好手动把backup这个账号单独加入对每一个盘的安全访问控制中。

因为win2000系统默认只是administrator这个账号和“every one”这个账号对磁盘有访问权限，如果对服务器做过安全配置去掉了every one这个账号的权限，那么将无法备份成功。

我们曾经就这样导致备份出错，无法检查出原因。

5、安装之前还有必要了解VERITAS EXEC组件的作用及安装，VERITAS EXEC有很多组件来实现不同的功能，这些组件也是需要单独来购买的，并且是按照使用数目来购买的。

而且安装的方法也是不一样的，有的需要在介质服务器端安装，有的要在远程目标服务器算安装。

具体如下：Veritas Backup Exec Windows NT/2000 v8.6 C-Adv Srv Ed主模块程序,既可以备份普通server,也可以备份advanced serve,只需要在介质服务器端安装●Veritas Backup Exec for winNT/2000,Open File Option实现对打开的文件进行备份的功能，在需要备份的每一台目标服务器上安装●Veritas Backup Exec Windows NT/2000 Intelligent DR Opt让VERITAS支持灾难备份/恢复的功能，要在介质服务器上安装●Veritas Backup Exec Windows NT/2000 Remote Agent可以利用介质服务器，从网络来备份服务器，需要在目标服务器上安装●Veritas Backup Exec Windows NT/2000 Remote Intelligent DR Opt实现远程灾备的功能，需要在服务器端注册一下，即输入SN就可以了，在注册该组件之前，必须要求有本地的IDR组件已经安装。

●Veritas Backup Exec Windows NT/2000 C-Lotus Domino Agent实现VERITAS对lotus进行备份，在介质服务器端安装就可以了●Veritas Backup Exec for winNT/2000, C-SQL Agent对SQL数据库进行备份，在介质服务器端安装，还必须要在介质服务器端安装SQL的客户端程序。

SQL2000的客户端可以兼容SQL7.0。

●Veritas Backup Exec Windows NT/2000 C-Oracle Agt对Oracle 数据库进行备份，在介质服务器端安装，完成以后在安装有Oracle 数据库的目标服务器也需要安装。

具体安装过程比较复杂。

后面详细介绍。

如果仅仅需要对WIN2000 SERVER服务器实现数据的备份/恢复，那么仅仅需要购买前三个模块就可以了，如果采用网络备份，则还需要增加Remote Agent 和Remote IDR组件一、介质服务器端的安装1、放入VERITASV9.1的光盘，光盘出现自启动的界面，如图一：（图一）2、点击“OK”以后，出现如图二的安装界面：（图二）3、点击Backup Exec安装，出现图三：（图三）4、点击“启动Backup Exec安装”出现图四：（图四）5、点击“下一步”出现图五，选择“我同意许可协议的各项条款”，然后点击下一步：（图五）6、出现图六，默认选择“本地安装”及“安装Backup Exec软件或选项”：然后点击下一步：7、图七，出现输入序列号的界面，你只要输入Exec和你所购买组件的序列号然后点击添加，Veritas会自动识别出你所安装的组件。

然后点击下一步：介质服务器端通常需要安装的组件有：本地IDR,远程IDR(仅仅注册一下，并不是真正的安装),选择安装路径、定制安装内容等，按照默认就可以了，点击下一步：8、图九，需要输入安装用户名和密码，注意一定要输入前面建立的同名账号来安装Exec，点击下一步：(图九)9、如图十，点击下一步，继续安装：（图十）10、图十一，出现一个安装回顾，以及系统的一些信息，并且会给出一些不符合安装要求的警告信息：（图十一）这样就完成了介质服务器端的安装，然后需要进行必要的配置二、介质服务器端Exec的配置配置向导第一次启动Exec会出现一个配置向导，来设置备份介质集的覆盖保护周期、设备配置、登陆用户等等基本配置信息，配置向导必须要走一遍，不能够取消，如果取消了将无法进入到VERITAS的使用界面中，个人认为“配置向导”不太实用，因此我建议配置向导都按照默认的选项点“下一步”就可以了，具体使用中需要的配置在进入VERITAS后再详细配置。

我按照自己的习惯在配置向导中作了一些配置如图一：(图一)1、首先是对介质集属性的配置：如图二介质管理设置是用来配置“介质集”的两个属性的，即：覆盖保护周期和附加周期（关于这两个术语的解释请查看手册），介质集可以理解为存放介质的容器，放入“介质集”的介质自动具有了“介质集”的两个属性的设置，向导默认是对自带的介质集1进行配置，我们通常是根据自己的需要来建立新的介质集，如图：下面将配置：首选覆盖介质类型，按照默认的选项点下一步即可。

完成以后出现“设备配置向导”，如图：2、设备配置向导用来配置磁带机，带库驱动器的过程，在Veritas是用备份设备之前，这些设备的驱动必须已经在系统下安装正常，veritas才能够发现这些设备。

我们采用“备份到文件夹”的方式，因此不需要备份设备，如图：下一步就会出现检测到“备份至磁盘”文件夹，我们不需要在这里配置，点“下一步”，按照默认完成即可3、登录账户向导：登录帐户向导是用来配置备份时访问介质服务器和目标服务器时的账户点下一步，完成账户向导的配置。

这样配置向导就完成了，我们可以看到Veritas的控制台界面了，如下图：如果我们安装了IDR组件还会出现一个IDR组件的配置向导，用来设置IDR 文件和备用IDR文件存放的位置，IDR文件在给每次做完完全备份后都会生成IDR在灾难备份的时候需要用到的，它包含了被恢复服务器的磁盘信息，计算机名称，网络配置等信息。

下面开始我们按照自己需要对VERITAS进行配置。

主要是：设备配置，介质配置，设置备份作业，制定备份策略和介质循环策略。

按需手动配置在手动对设备和介质集进行配置之前，你必须要有一个备份策略，还要对你的备份总数据量与备份的时间窗口之间进行计算。

备份策略是指你打算采用的备份方法和打算对数据保护的周期。

备份方法有：完全备份，差分备份，增量备份三种，具体的概念请查阅相关资料。

你可以采用一种或者三种方法相结合的备份方法。

企业备份通常是采用三种相结合方法：如果数据的保护周期为一个月，那么我们可以这样设置：每两周作一次完全备份，每天做增量备份，每周作一次差别备份。

备份总数据量与备份的时间窗口的问题在对带库设备进行选形时比较重要，我们使用磁盘作为备份设备，不需要考虑这个问题。

好了有了一个明确的备份策略就可以手动按需配置Veritas了设备配置点击“设备”进入设备管理的窗口，我们可以看到本机仅有一个“备份至磁盘”的设备可用，如图：右键点击“备份至磁盘”，在出现的菜单中选择“新建备份文件夹”，如图：出现下图，按照下图的说明完成配置。

在这里有必要说明一下，备份的设备有多种：磁带机，带库，刻录机和磁盘，在这里我们就采用“备份至磁盘文件夹”这个设备来备份数据，每一个文件夹就相当于一个磁带机，备份的数据也是存在这个文件夹中。

因此如果有多台服务器，经过我多次的实践建议为每一台服务器都建立一个“备份至磁盘”驱动器，并且按照服务器的名称来建立“备份至磁盘”驱动器的名称，对应的实际物理文件夹也和驱动器的命名一样。

虽然这不是必需的，但这样会让你的备份更具条理性。

下图是我根据我的服务器建立的“备份至磁盘”文件夹：右键选择刚才建好的“web服务器”，点击“属性”,在出现的属性窗口中选择“高级”，把“最大的备份至磁盘文件”的1G大小修改的大一些，不然你对一个服务器备份的数据超过了1G，那么在该文件夹下就会出现多个大小为1G 的文件，这样修改可以让备份数据只有一个文件。

这样就完成了设备的配置。
