一、基本信息
1 数据库当前的设备如下name phyname------------------------------ ------------------------master /dev/rlv_master sysprocsdev /dev/rlv_proc 2 rootvg的lv信息# lsvg -l rootvg rootvg:LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINT hd5 boot 1 1 1 closed/syncd N/A hd6 paging 64 64 1 open/syncd N/A hd8 jfs2log 1 1 1 open/syncd N/A hd4 jfs2 48 48 1 open/syncd / hd2 jfs2 64 64 1 open/syncd /usr hd9var jfs2 48 48 1 open/syncd /var hd3 jfs2 48 48 1 open/syncd /tmp hd1 jfs2 1 1 1 open/syncd /home hd10opt jfs2 48 48 1 open/syncd /opt lg_dumplv sysdump 16 16 1 open/syncd N/A lv_master raw 5 5 1 open/syncd N/A lv_proc raw 5 5 1 open/syncd N/A lv_data1 raw 16 16 1 closed/syncd N/A 3 sybase RUN_CRM 文件内容如下$ cat RUN_CRM#!/bin/sh## Adaptive Server name: CRM# ASE page size (KB): 2k# Master device path: /dev/rlv_master# Error log path: /sybase/ASE-12_5/install/CRM.log# Configuration file path: /sybase/ASE-12_5/CRM.cfg# Directory for shared memory files: /sybase/ASE-12_5#/sybase/ASE-12_5/bin/dataserver \-sCRM \-d/dev/rlv_master \-e/sybase/ASE-12_5/install/CRM.log \-c/sybase/ASE-12_5/CRM.cfg \-M/sybase/ASE-12_5 \4 sybase的接口文件内容如下：# cat interfaces CRM master tcp ether 192.168.85.9 5000 query tcp ether 192.168.85.9 5000 CRM_back master tcp ether 192.168.85.9 5001 query tcp ether 192.168.85.9 5001
二、拷贝sybase的所有相关lv、本例sybase只有lv_master lv_proc两个lv （注意由于是简单模拟实验，所以sybase就只有这么两个lv）
1 拷贝过程如下：
cplv命令解释如下：
-y 新的lv名字-v 目标卷组名字# cplv -y newlv_master -v datavg lv_master cplv: Logical volume lv_master successfully copied to newlv_master .
# cplv -y newlv_proc -v datavg lv_proc cplv: Logical volume lv_proc successfully copied to newlv_proc .
2 拷贝lv后datavg 的lv信息如下：# lsvg -l datavg datavg:LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINT lv_backup jfs2 320 320 1 open/syncd /backup loglv00 jfs2log 1 1 1 open/syncd N/A newlv_master raw 10 10 1 closed/syncd N/A newlv_proc raw 10 10 1 closed/syncd N/A
三、更改lv名字
1 更改原rootvg上sybaselv的名字
chlv命令参数解释如下：
-n 为新lv名字# chlv -n oldlv_master lv_master# chlv -n oldlv_proc lv_proc 2 更改datavg上lv名字（由newlv_master--> lv_master| newlv_proc-->lv_proc)# chlv -n lv_master newlv_master# chlv -n lv_proc newlv_proc
四、启动服务后测试情况如下
1 启动主服务和备份服务$ startserver -f RUN_CRM$ startserver -f RUN_CRM_back 2 验证如下可看到sybase主备服务已经启动成功$ showserver USER PID %CPU %MEM SZ RSS TTY STAT STIME TIME COMMAND sybase 319558 2.0 2.0 25564 17188 pts/1 A 11:42:25 0:03 /sybase/ASE-12_5/bin/dataserver -sCRM -d/dev/rlv_master -e/sybase/ASE-12_5/install/CRM.log -c/sybase/ASE-12_5/CRM.cfg -M/sybase/ASE-12_5 sybase 286878 0.0 1.0 7016 7440 pts/1 A 11:43:14 0:00 /sybase/ASE-12_5/bin/backupserver -SCRM_back -e/sybase/ASE-12_5/install/CRM_back.log -Ldefault -Jcp850 -N25 -C20 -M/sybase/ASE-12_5/bin/sybmultbuf验证下master库能否备份，如下：$ isql -Usa -P -SCRM 1> dump database master to '/backup/master2.dat'2> go WARNING: In order to LOAD the master database, the SQL Server must run in single-user mode. If the master database dump uses multiple volumes, you must execute sp_volchanged on another SQL Server at LOAD time in order to signal volume changes.
