2、上的数据访问太密集时, 可以将其数据转移到另外的Volume 上去。DMP(Dynamic Multi path)功能, 改进I/O 吞吐率, 且支持冗余。二. 安装和配置说明1.软件安装前的准备和说明 $PATH=/sbin:/user/sbin:/opt/VRTS/bin: $PATH;export PATH (将此路径加入/etc/profile) 必须有 /opt目录 为了初始化volume manager必须有许可证密匙和cluster功能许可证 使用volume manager是为了管理磁盘阵列 安装前,确认磁盘阵列的分配布局 安装前,确认rootdg的位置如c1t0d0s0。ro

3、otdg必须存在。 有volume manager管理的磁盘应有两个空闲分区和少量空闲空间 一般在封装一块内置硬盘后，volume manager会清空第4,5分区，所以在安装操作系统后,不要在这两分区上装软件，这两分区也不要和其他的文件系统挂接 在系统硬盘上必须有足够的空间来安装软件 操作系统是solaris8 一般安装的顺序是先安装操作系统，然后是volume manager，然后是cluster，然后是sybase和其他的应用程序2. 软件安装 将Veritas volume manager CD 盘放入 CDROM中 进入/cdrom/cdrom0,运行./installer，进行安装

4、软件包。 安装完毕后进入安装菜单，选择1安装license。 安装完后选择2再选1进行软件安装。3. 配置和使用 Volume Manager Volume Manager 是以磁盘组（Disk Group）为管理单元，其中rootdg必不可少，在其中包含Volume Manager 的启动信息。在系统中，有rootdg、datadg 2个Disk Group，rootdg 建在c1t1d0s0(举例)上。 创建rootdg(操作系统安装在c1t0d0上)用vxinstall创建rootdg简单#vxconfigd m disable 停后台进程#vxdctl init 磁盘控制初始化# vx

7、roup, select a disk group name that does not yet exist. Disk c1t0d0 contains one of these file systems: / /usr /var. As a result it must be encapsulated to the rootdg disk group.Hit RETURN to continue.按回车继续Which disk group ,list,q,? (default: rootdg) Use a default disk name for the disk? y,n,q,? (de

10、uld now reboot your system at the earliest possible opportunity. The encapsulation will require two or three reboots which will happen automatically after the next reboot. To reboot execute the command:shutdown -g0 -y -i6Continue with encapsulation? y,n,q,? (default: y) n 是否继续封装This will update the

11、/etc/vfstab file so that volume devices are used to mount the file systems on this disk device. You will need to update any other references such as backup scripts, databases, or manually created swap devices.Encapsulate other disks? y,n,q,? (default: n) 是否继续封装其它磁盘封装结束。重启系统(reboot)。删除c1t1d0s0和c1t1d0
