本次任务为使用uuid绑定磁盘后安装数据库
找到对应安装在vmware目录下的vmware-vdiskmanager.exe

使用命令行打开（可用cmd，本文使用powershell）

cd 'C:\Program Files (x86)\VMware\VMware Workstation'
ls vmware-vdiskmanager.exe

有以下输出证明路径正确

本次规划的目标

磁盘名称	空间大小
DCR	100MB
VOTE	200MB
REDO	1GB
DATA	10GB
ARCHIVE	5GB

存放目标目录为D:\vmware\share_disk

.\vmware-vdiskmanager.exe -c -s 100MB -a lsilogic -t 2 "D:\vmware\share_disk\DCR.vmdk"
.\vmware-vdiskmanager.exe -c -s 200MB -a lsilogic -t 2 "D:\vmware\share_disk\VOTE.vmdk"
.\vmware-vdiskmanager.exe -c -s 2GB -a lsilogic -t 2 "D:\vmware\share_disk\REDO.vmdk"
.\vmware-vdiskmanager.exe -c -s 10GB -a lsilogic -t 2 "D:\vmware\share_disk\DATA.vmdk"
.\vmware-vdiskmanager.exe -c -s 5GB -a lsilogic -t 2 "D:\vmware\share_disk\ARCHIVE.vmdk"

回到目录，磁盘已经创建完成

重复操作4次

添加5个磁盘到虚拟机1中（由于篇幅问题，步骤已经省略，步骤可以在过去的博文中找到）
在虚拟机1的文件夹中找到.vmx加入

disk.locking=false
disk.EnableUUID = "TRUE"
#如果想要使用uuid，可以加入EnableUUID 

添加5个磁盘到虚拟机2中（由于篇幅问题，步骤已经省略，步骤可以在过去的博文中找到）

进入第二台虚拟机中，在虚拟机2的文件夹中找到.vmx加入设置所有的bus 共享

disk.locking=false
disk.EnableUUID = "TRUE"
#如果想要使用uuid，可以加入EnableUUID 

虚拟机1和虚拟机2同样的磁盘需要在虚拟机中设定好对应的SCSI(添加磁盘的顺序不能错)

启动虚拟机即可查看到共享磁盘组

虚拟机1

在虚拟机中如果发现新增磁盘之后fdisk -l 不显示
则进入root输入
（虚拟机有三根总线）

[root@localhost dmdba]# echo "- - -" > /sys/class/scsi_host/host0/scan
[root@localhost dmdba]# echo "- - -" > /sys/class/scsi_host/host1/scan
[root@localhost dmdba]# echo "- - -" > /sys/class/scsi_host/host2/scan

查询对应的uuid是否一致

#使用SCSI绑定检测uuid是否一致
for i in b c d e f g;
do
/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/sd$i
done

如果使用的是nvme硬盘

for i in b c d e f g;
do
ls -la /dev/disk/by-id|grep nvme

之后搭建dsc集群

7. 修改权限，编辑两个节点的/etc/udev/rules.d/60-raw.rules 文件

KERNEL=="sd?",SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name",RESULT=="36000c29c410a60e54ae604a731e06cc9", SYMLINK+="dmdcr",OWNER="dmdba", GROUP="dinstall",MODE="0660"

9. 执行

udevadm trigger --action=add

配置DSC节点文件

1. 在DSC0上配置/dm/data/dsc/dmdcr_cfg.ini

DCR_N_GRP                = 3
DCR_VTD_PATH             = /dev/dmvote
DCR_OGUID                = 210331

[GRP]
  DCR_GRP_TYPE           = CSS
  DCR_GRP_NAME           = GRP_CSS
  DCR_GRP_N_EP           = 2
  DCR_GRP_DSKCHK_CNT     = 65
[GRP_CSS]
  DCR_EP_NAME            = CSS0
  DCR_EP_HOST            = 192.168.48.20
  DCR_EP_PORT            = 31286
[GRP_CSS]
  DCR_EP_NAME            = CSS1
  DCR_EP_HOST            = 192.168.48.21
  DCR_EP_PORT            = 31286

[GRP]
  DCR_GRP_TYPE           = ASM
  DCR_GRP_NAME           = GRP_ASM
  DCR_GRP_N_EP           = 2
  DCR_GRP_DSKCHK_CNT     = 61
[GRP_ASM]
  DCR_EP_NAME            = ASM0
  DCR_EP_SHM_KEY         = 42424
  DCR_EP_SHM_SIZE        = 200
  DCR_EP_HOST            = 192.168.48.20
  DCR_EP_PORT            = 31276
  DCR_EP_ASM_LOAD_PATH   = /dev
[GRP_ASM]
  DCR_EP_NAME            = ASM1
  DCR_EP_SHM_KEY         = 42425
  DCR_EP_SHM_SIZE        = 200
  DCR_EP_HOST            = 192.168.48.21
  DCR_EP_PORT            = 31277
  DCR_EP_ASM_LOAD_PATH   = /dev

[GRP]
  DCR_GRP_TYPE           = DB
  DCR_GRP_NAME           = GRP_DSC
  DCR_GRP_N_EP           = 2
  DCR_GRP_DSKCHK_CNT     = 57
[GRP_DSC]
  DCR_EP_NAME            = DSC_DSC0
  DCR_EP_SEQNO           = 0
  DCR_EP_PORT            = 5236

2. 双节点使用DMASMCMD初始化

create dcrdisk '/dev/dmdcr' 'dcr'
create votedisk '/dev/dmvote' 'vote'
create asmdisk '/dev/dmarchive' 'LOG0'
create asmdisk '/dev/dmdata' 'DATA0'
init dcrdisk '/dev/dmdcr' from '/dm/data/dsc/dmdcr_cfg.ini' identified by 'abcd'
init votedisk '/dev/dmvote' from '/dm/data/dsc/dmdcr_cfg.ini'

3. 双节点配置dmasvrmal.ini
   两节点内容完全一样

[MAL_INST0]
MAL_INST_NAME            = ASM0
MAL_HOST                 = 192.168.48.20
MAL_PORT                 = 31266
[MAL_INST1]
MAL_INST_NAME            = ASM1
MAL_HOST                 = 192.168.48.21
MAL_PORT                 = 31266

4. DSC0节点配置dmdcr.ini

DMDCR_PATH                   = /dev/dmdcr
DMDCR_MAL_PATH               = /dm/dsc_config/DSC_DSC0/dmasvrmal.ini
DMDCR_SEQNO                  = 0
DMDCR_ASM_RESTART_INTERVAL   = 71
DMDCR_ASM_STARTUP_CMD        = /dm/dsc_config/DmAsmServiceDSC_DSC0 start
DMDCR_DB_RESTART_INTERVAL    = 0
DMDCR_DB_STARTUP_CMD         = /dm/dsc_config/DmServiceDSC_DSC0 start
DMDCR_AUTO_OPEN_CHECK        = 111

5. DSC1节点配置dmdcr.ini

DMDCR_PATH                   = /dev/dmdcr
DMDCR_MAL_PATH               = /dm/dsc_config/DSC_DSC1/dmasvrmal.ini
DMDCR_SEQNO                  = 0
DMDCR_ASM_RESTART_INTERVAL   = 71
DMDCR_ASM_STARTUP_CMD        = /dm/dsc_config/DmAsmServiceDSC_DSC1 start
DMDCR_DB_RESTART_INTERVAL    = 0
DMDCR_DB_STARTUP_CMD         = /dm/dsc_config/DmServiceDSC_DSC1 start
DMDCR_AUTO_OPEN_CHECK        = 111

6. 在DSC0和DSC1先后启动dmcss、dmasmsvr

./dmcss DCR_INI=/dm/data/dsc/dmdcr.ini #dmcss

./dmasmsvr DCR_INI=/dm/data/dsc/dmdcr.ini #dmasmsvr

7. 单独启动dmcss只有如下输出
   

8. 只启动DSC0dmcss与dmasmsvr会只有以下输出
   

9. 两集群真正启动之后就会有如下效果
   

10. Dsc0节点启动dmasmtool创建共享磁盘

./dmasmtool DCR_INI=/dm/data/dsc/dmdcr.ini
create diskgroup 'DMLOG' asmdisk '/dev/dmarchive'  #创建磁盘日志组
create diskgroup 'DMDATA' asmdisk '/dev/dmdata' #创建数据磁盘组

11. 在/dm/data/dsc目录下新建一个dminit.ini文件

DB_NAME                  = DSC_DSC
SYSDBA_PWD               = SYSDBA_PWD
SYSTEM_PATH              = +DMDATA/data
SYSTEM                   = +DMDATA/data/SYSTEM.dbf
SYSTEM_SIZE              = 1024
ROLL                     = +DMDATA/data/ROLL.dbf
ROLL_SIZE                = 1024
MAIN                     = +DMDATA/data/MAIN.dbf
MAIN_SIZE                = 1024
CTL_PATH                 = +DMDATA/data/dm.ctl
CTL_SIZE                 = 8
LOG_SIZE                 = 256
DCR_PATH                 = /dev/dmdcr
DCR_SEQNO                = 0
AUTO_OVERWRITE           = 1
PAGE_SIZE                = 16
EXTENT_SIZE              = 16
CASE_SENSITIVE           = 1
UNICODE_FLAG             = 0

[DSC_DSC0]
CONFIG_PATH              = /dm/dsc_config/DSC_DSC0
PORT_NUM                 = 5236
MAL_HOST                 = 192.168.48.20
MAL_PORT                 = 31246
LOG_PATH                 = +DMLOG/DSC_DSC0_LOG01.log
LOG_PATH                 = +DMLOG/DSC_DSC0_LOG02.log
[DSC_DSC1]
CONFIG_PATH              = /dm/dsc_config/DSC_DSC1
PORT_NUM                 = 5236
MAL_HOST                 = 192.168.48.21
MAL_PORT                 = 31246
LOG_PATH                 = +DMLOG/DSC_DSC1_LOG01.log
LOG_PATH                 = +DMLOG/DSC_DSC1_LOG02.log

12. 启动dminit初始化DB环境
    DSC0执行以下命令

./dminit control=/dm/data/dsc/dminit.ini

22. 将dsc1_config文件夹发送到dsc1的相同目录下

启动DMDSC集群

1. 分别在dsc0和dsc1下启动dmserver即可完成dsc搭建

./dmserver /dm/data/dsc0_config/dm.ini dcr_ini=/dm/data/dsc/dmdcr.ini #dsc0
./dmserver /dm/data/dsc1_config/dm.ini dcr_ini=/dm/data/dsc/dmdcr.ini`#dsc1

monitor配置

配置dmcssm.ini

CSSM_OGUID                = 210331
  
CSSM_CSS_IP            = 192.168.48.20:31286
CSSM_CSS_IP            = 192.168.48.21:31286

CSSM_LOG_PATH          = /dm/log
CSSM_LOG_FILE_SIZE     = 16
CSSM_LOG_SPACE_LIMIT   = 512

在monitor启动监视器

./dmcssm INI_PATH=/dm/data/dmcssm.ini

输入show命令即可看到当前状态
