Oracle RAC 部署 （VMware共享磁盘配置方法）

# 参考 https://www.cnblogs.com/cynriczgc/p/16951943.html

# 1、以管理员方式打开DOS窗口，到vmware workstation安装目录下，执行以下命令创建需要的共享磁盘：

vmware-vdiskmanager.exe -c -s 20GB -a lsilogic -t 2 "E:\ORACL_RAC_BLOCK\votingdisk1.vmdk"
vmware-vdiskmanager.exe -c -s 20GB -a lsilogic -t 2 "E:\ORACL_RAC_BLOCK\votingdisk2.vmdk"
vmware-vdiskmanager.exe -c -s 20GB -a lsilogic -t 2 "E:\ORACL_RAC_BLOCK\votingdisk3.vmdk"
vmware-vdiskmanager.exe -c -s 20GB -a lsilogic -t 2 "E:\ORACL_RAC_BLOCK\votingdisk4.vmdk"
vmware-vdiskmanager.exe -c -s 20GB -a lsilogic -t 2 "E:\ORACL_RAC_BLOCK\votingdisk5.vmdk"
vmware-vdiskmanager.exe -c -s 20GB -a lsilogic -t 2 "E:\ORACL_RAC_BLOCK\votingdisk6.vmdk"
vmware-vdiskmanager.exe -c -s 20GB -a lsilogic -t 2 "E:\ORACL_RAC_BLOCK\votingdisk7.vmdk"

# 2、修改2个虚拟机的vmx配置文件，在虚拟机的安装目录下的.vmx文件最后加上以下信息：

scsi1.virtualDev = "lsilogic"
scsi1.present = "TRUE"
 
scsi1:0.filename = "E:\ORACL_RAC_BLOCK\votingdisk1.vmdk"
scsi1:0.mode = "independent-persistent"
scsi1:0.present = "TRUE"
 
scsi1:1.filename = "E:\ORACL_RAC_BLOCK\votingdisk2.vmdk"
scsi1:1.mode = "independent-persistent"
scsi1:1.present = "TRUE"
 
scsi1:2.filename = "E:\ORACL_RAC_BLOCK\votingdisk3.vmdk"
scsi1:2.mode = "independent-persistent"
scsi1:2.present = "TRUE"
 
scsi1:3.filename = "E:\ORACL_RAC_BLOCK\votingdisk4.vmdk"
scsi1:3.mode = "independent-persistent"
scsi1:3.present = "TRUE"
 
scsi1:4.filename = "E:\ORACL_RAC_BLOCK\votingdisk5.vmdk"
scsi1:4.mode = "independent-persistent"
scsi1:4.present = "TRUE"
 
scsi1:5.filename = "E:\ORACL_RAC_BLOCK\votingdisk6.vmdk"
scsi1:5.mode = "independent-persistent"
scsi1:5.present = "TRUE"
 
scsi1:6.filename = "E:\ORACL_RAC_BLOCK\votingdisk7.vmdk"
scsi1:6.mode = "independent-persistent"
scsi1:6.present = "TRUE"
 
scsi1.sharedBus = "virtual"
disk.locking = "false"
diskLib.dataCacheMaxSize = "0"
diskLib.dataCacheMaxReadAheadSize = "0"
diskLib.dataCacheMinReadAheadSize = "0"
diskLib.dataCachePageSize = "4096"
diskLib.maxUnsyncedWrites = "0"
disk.EnableUUID = "TRUE"


# 参考 https://zhuanlan.zhihu.com/p/552268323

# 3、查询磁盘UUID

for disk in `ls /dev/sd*`
do
    echo -en "$disk\t"
    /usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=$disk
done

# 4、编辑udev文件

# vi /etc/udev/rules.d/99-oracleasm.rules

KERNEL=="sd?", SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id -g -u -d /dev/$name", RESULT=="36000c29828eb23bfc7af48736e1db094", SYMLINK+="asm-diska", OWNER="grid", GROUP="asmadmin", MODE="0660"
KERNEL=="sd?", SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id -g -u -d /dev/$name", RESULT=="36000c29e930e17110e7156996be9b2a5", SYMLINK+="asm-diskb", OWNER="grid", GROUP="asmadmin", MODE="0660"
KERNEL=="sd?", SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id -g -u -d /dev/$name", RESULT=="36000c29e43fa2988513b7228780d9db8", SYMLINK+="asm-diskc", OWNER="grid", GROUP="asmadmin", MODE="0660"
KERNEL=="sd?", SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id -g -u -d /dev/$name", RESULT=="36000c296bd2494fb29af055c17c7397b", SYMLINK+="asm-diskd", OWNER="grid", GROUP="asmadmin", MODE="0660"
KERNEL=="sd?", SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id -g -u -d /dev/$name", RESULT=="36000c291aaf1c48a7b32459ee6d56bcc", SYMLINK+="asm-diske", OWNER="grid", GROUP="asmadmin", MODE="0660"
KERNEL=="sd?", SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id -g -u -d /dev/$name", RESULT=="36000c298cbf6e5fa1582001970c59b11", SYMLINK+="asm-diskf", OWNER="grid", GROUP="asmadmin", MODE="0660"

# 5、加载udev规则

/sbin/udevadm trigger --type=devices --action=change
/sbin/udevadm control --reload-rules

# 6、验证

ll /dev/asm*

# 7、如果权限不对，就手工刷新

chown grid.asmadmin /dev/sdb 
chmod 660 /dev/sdb 

当然出了这种方案以外，还可以使用iSCSI
