1.1 下载软件
go.symantec/vcsmc
SF for RAC Release 5.1 on LINUX
对应软件包 VRTS_SF_HA_Solutions_5.1_PR1_RHEL5_SLES10_
Veritas Enterprise Administrator 3.4.15.0 (Linux)
对应软件包 VRTSobgui-3.4.15.0-0.i686.rpm
VCS Cluster Manager Java_Console 5.1 (Linux)
对应软件包 VCS_Cluster_Manager_Java_Console_5.1_for_Linux.rpm
1.2 准备工作
# 软件要求
Software Version
Database Oracle RAC 11g Release 2
Operatingsystem
Red Hat Enterprise Linux 5 (RHEL 5) Update 3 or later
Oracle Enterprise Linux 5.3 (OEL 5.3) or later
SUSE Linux Enterprise Server 10 with SP2 (SLES 10 SP2)
SUSE Linux Enterprise Server 10 with SP3 ( SLES 10 SP3)
# 配置/etc/hosts
在2 台主机/etc/hosts 上增加各自的IP
192.168.0.49 host1
192.168.0.50 host2
# 配置2 个节点root 用户的ssh 信任
# 配NTP
# 准备共享磁盘
存储上的 lun 必须对所有节点可见。
共享存储必须支持SCSI-3 Persistent Reservations (PR ，永久保留功能).
SCSI-3 PR 就是一组SCSI 命令集，用在多个系统访问一个共享存储的时候协调
之用。
安装完 SF 后可用 vxfentsthdw 可做检查。
/opt/VRTS/bin/vxfentsthdw
# cd /opt/VRTS/bin
#./vxfentsthdw
VERITAS vxfentsthdw version 5.1.001.000-RP1 Linux
The utility vxfentsthdw works on the two nodes of the cluster. The utility verifies that the shared storage one intends to use isconfigured to support I/O fencing. It issues a series of vxfenadm commands to setup SCSI-3 registrations on the disk, verifies the registrations on the disk, and removes the registrations from the disk.
******** WARNING ********
THIS UTILITY WILL DESTROY THE DATA ON THE DISK!!

# I/O fencing 策略
对于采用 cluster file system 的 veritas ha 方案，一定要采用共享磁盘做
I/O fencing ；
对于单机的 file system ，在确保有 2 个直连网线和 1 个 bond 的业务网络的情况下，可以不考虑 I/O fencing 的策略。
Make sure that the I/O fencing coordinator disks meet the following requirements:
* For disk-based I/O fencing, you must have three coordinator disks.  * The coordinator disks can be raw devices, DMP devices, or iSCSI devices.  You must use DMP disk policy for iSCSI-based coordinator disks.
* Each of the coordinator disks must use a physically separate disk or LUN.linux安装oracle数据库(rpm方式安装)
Symantec recommends using the smallest possible LUNs for coordinator disks.
* The coordinator disks must support SCSI-3 persistent reservations.  *Symantec recommends using hardware-based mirroring for coordinator disks.
* Coordinator disks must not be used to store data or must not be included in disk groups that store user data.
* Coordinator disks cannot be the special devices that array vendors use. For example, you cannot use EMC gatekeeper devices as coordinator disks.  # 配置环境变量
vi /root/.bash_profile
export MANPATH=$MANPATH:/opt/VRTS/man
PATH=$PATH:$HOME/bin
PATH=$PATH:\
/usr/lib/vxvm/bin:/opt/VRTSvcs/bin:\
/opt/VRTS/bin:/opt/VRTSvcs/rac/bin:\
/opt/VRTSob/bin;
export PATH
# 配置 linux I/O 调度策略
Symantec recommends using the Linux 'deadline' I/O scheduler for database  workloads. Configure your system to boot with the 'elevator=deadline' argument
to select the 'deadline' scheduler.
查看当前的 IO 调度策略，默认选择 CFQ 做为 I/O 调度器
cat /sys/block/sd*/queue/scheduler
修改调度策略
vi /boot/grub/menu.lst
kernel /boot/vmlinuz-2.6.18-128.el5 ro root=LABEL=/
改为
kernel /boot/vmlinuz-2.6.18-128.el5 ro root=LABEL=/ elevator=deadline  重启OS ，检查是否修改生效。
# 网络要求
网络要求 1 个走交换机的业务网段， 1 个网线直连的私有网段。
私有网段的网口要用直连网线连接，作为首选心跳，争取可以配 2 条直连网线。业务网络网卡要求 2 张独立网卡做 bond ，可以作为备用心跳线。
每个机器业务网段的 2 个 bond 网口分别上联到 2 个独立的网络交换机上面。
