VCS5.0命令

执行VCS命令需要用root用户登陆。命令都在/opt/VRTS/bin名录下，确信该目录已经设置到root用户下的PATH环境变量里。

验证节点信息和状态（可执行于任一节点）： # hastatus -sum

确保所有的device和resource groups是online状态。 VCS软件信息查看： # rpm -q VRTSvcs # ls /opt/VRTS*

# pkginfo -l | grep VERITAS # pkginfo -l | grep VRTS

查看VCS配置（可执行于任一节点）： # cd /etc/VRTSvcs/conf/config/ # more main.cf

查看VCS日志（可执行于任一节点）： # tail -100f /var/VRTSvcs/log/engine_A.log 关闭集群（仅执行于某一节点）： # hastop -all

在ok提示符下重启集群（需执行于每一节点）： {#} hastart

验证私网即心跳线状态（可执行于任一节点）： # gabconfig -a

验证公网状态（可执行于任一节点）： # config -a

查看私网使用信息： # lltstat -nvv

umount共享磁盘： # umount -f /mountpoint

VCS会自动mount共享磁盘到另外一节点。 资源组从主节点切换到备节点： # hagrp oracleSG -switch to 资源组冻结： # hagrp -freeze

所有的设备组和资源组应该切换到另一节点了。 磁盘列表： # vxdisk list

# hagrp -switch groupy -to hosta

Here's a procedure to upgrade VCS or shutdown VCS during hardware maintenance.

1. Open, freeze each Service Group, and close the VCS config. haconf -makerw

hagrp -freeze -persistent haconf -dump makero

2. Shutdown VCS but keep services up. hastop -all -force

3. Confirm VCS has shut down on each system. gabconfig -a

4. Confirm GAB is not running on any disks.

gabdisk -l (use this if upgrading from VCS 1.1.x) gabdiskhb -l gabdiskx -l

If it is, remove it from the disks on each system. gabdisk -d (use this if upgrading from VCS 1.1.x) gabdiskhb -d gabdiskx -d

5. Shutdown GAB and confirm it's down on each system. gabconfig -U gabconfig -a

6. Identify the GAB kernel module number and unload it from each system. modinfo | grep gab modunload -i

7. Shutdown LLT. On each system, type: lltconfig -U

Enter \

8. Identify the LLT kernel module number and unload it from each system. modinfo | grep llt modunload -i

9. Rename VCS startup and stop scripts on each system.

cd /etc/rc2.d mv S70llt s70llt mv S92gab s92gab cd /etc/rc3.d

mv S99vcs s99vcs cd /etc/rc0.d

mv K10vcs k10vcs

10. Make a backup copy of /etc/VRTSvcs/conf/config/main.cf. Make a backup copy of /etc/VRTSvcs/conf/config/types.cf.

Starting with VCS 1.3.0, preonline and other trigger scripts must be in /opt/VRTSvcs/bin/triggers. Also, all preonline scripts in

previous versions (such as VCS 1.1.2) must now be combined in one preonline script.

11. Remove old VCS packages.

pkgrm VRTScsga VRTSvcs VRTSgab VRTSllt VRTSperl VRTSvcswz If you are upgrading from 1.0.1 or 1.0.2, you must also remove the package VRTSsnmp, and any packages containing a .2 extension, such as VRTScsga.2, VRTSvcs.2, etc.

Also remove any agent packages such as VRTSvcsix (Informix),

VRTSvcsnb (NetBackup), VRTSvcssor (Oracle), and VRTSvcssy (Sybase). Install new VCS packages.

Restore your main.cf and types.cf files. 12. Start LLT, GAB and VCS. cd /etc/rc2.d mv s70llt S70llt mv s92gab S92gab cd /etc/rc3.d

mv s99vcs S99vcs cd /etc/rc0.d

mv k10vcs K10vcs /etc/rc2.d/S70llt start /etc/rc2.d/S92gab /etc/rc3.d/S99vcs start 13. Check on status of VCS. hastatus

hastatus -sum

14. Unfreeze all Service Groups. haconf -makerw

hagrp -unfreeze -persistent haconf -dump -makero
