一、Redhel 7.0 配置 ASM 磁盘,并用 udev 绑定

1.虚拟机需要在 vmx 文件中添加，才能显示 UUID

disk.enableUUID = "TRUE"

步骤 2(使用循环生成文件)

#for i in b c d e f g;

echo "KERNEL==\"sd*\", ENV{DEVTYPE}==\"disk\", SUBSYSTEM==\"block\",

PROGRAM==\"/usr/lib/udev/scsi_id -g -u -d \$devnode\",

RESULT==\"`/usr/lib/udev/scsi_id -g -u /dev/sd$i`\", RUN+=\"/bin/sh -c 'mknod

/dev/asmdisk$i b \$major \$minor; chown grid:asmadmin /dev/asmdisk$i; chmod 0660

/dev/asmdisk$i'\"" >>/etc/udev/rules.d/99-oracle-asmdevices.rules

done

步骤 3（启动 Udev）

#/sbin/udevadm trigger --type=devices --action=change

步骤 2

查看各磁盘的 UUID

for i in a b c d e f g

/usr/lib/udev/scsi_id -g -u -d /dev/sd$i

done

或者：

步骤 2

cd /dev/disk/by-id

查看各磁盘的 UUID

另外一种查看方式：

# /usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/sdb

1ATA_VBOX_HARDDISK_VB07fbdbc7-a8414329

# /usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/sdc

1ATA_VBOX_HARDDISK_VB253cd409-8587c441

redhat 7.0 (如下)

# cat 99-oracle-asmdevices.rules

启动 udev

#/sbin/udevadm trigger --type=devices --action=change

# /sbin/start_udev

LISTENER.LOG 文件过大的处理办法：

当然也可以移走监听日志文件（listener.log），数据库实例会自动创建一个 listener.log 文件。

% lsnrctl set log_status off

% mv listener.log listener.yyyymmdd

% lsnrctl set log_status on

dd if=/dev/zero of=/dev/sdb bs=8192 count=128000

dd if=/dev/zero of=/dev/sdc bs=8192 count=128000

dd if=/dev/zero of=/dev/sdd bs=8192 count=128000

dd if=/dev/zero of=/dev/sde bs=8192 count=128000

dd if=/dev/zero of=/dev/sdf bs=8192 count=128000

dd if=/dev/zero of=/dev/sdg bs=8192 count=128000

redhat 7.4 (如下) (multipath -ll) LUN 是走 FC 挂过去的正常每个 LUN 都要能识别四条路

径

# cat 99-oracle-asmdevices.rules
