Oracle RAC集群搭建--挂在磁盘

Posted 2021-02-11 kingle66

一,磁盘配置

　　查看由上回配置的共享磁盘,一共三块-----以下所有内容均两台物理机都需要操作

查看磁盘id

[root@rac2 ~]# /usr/lib/udev/scsi_id -g -u /dev/sdd
36000c293f44d71c233c240a4c150b475
[root@rac2 ~]# /usr/lib/udev/scsi_id -g -u /dev/sdc
36000c2954a30394730cfbb390b97587c
[root@rac2 ~]# /usr/lib/udev/scsi_id -g -u /dev/sdb
36000c29094e87ed8386bf78cd5dcb80e
[root@rac2 ~]#

分配

[root@rac2 ~]# cat /etc/udev/rules.d/99-oracle-asmdevices.rules
KERNEL=="sd*[!0-9]", ENV{DEVTYPE}=="disk", SUBSYSTEM=="block",  PROGRAM=="/usr/lib/udev/scsi_id -g -u -d $devnode",  RESULT=="36000c29094e87ed8386bf78cd5dcb80e", RUN+="/bin/sh -c \'mknod /dev/asmdisk01 b  $major $minor; chown grid:oinstall /dev/asmdisk01; chmod0660 /dev/asmdisk01\'"
KERNEL=="sd*[!0-9]", ENV{DEVTYPE}=="disk", SUBSYSTEM=="block",  PROGRAM=="/usr/lib/udev/scsi_id -g -u -d $devnode",  RESULT=="36000c2954a30394730cfbb390b97587c", RUN+="/bin/sh -c \'mknod /dev/asmdisk02 b  $major $minor; chown grid:oinstall /dev/asmdisk02; chmod0660 /dev/asmdisk02\'"
KERNEL=="sd*[!0-9]", ENV{DEVTYPE}=="disk", SUBSYSTEM=="block",  PROGRAM=="/usr/lib/udev/scsi_id -g -u -d $devnode",  RESULT=="36000c293f44d71c233c240a4c150b475", RUN+="/bin/sh -c \'mknod /dev/asmdisk03 b  $major $minor; chown grid:oinstall /dev/asmdisk03; chmod0660 /dev/asmdisk03\'"
[root@rac2 ~]#

二,诊断

　　01,检查新设备

　[root@rac1 ~]#  /sbin/udevadm trigger --type=devices --action=change

　　02,重新加载UDEV

[root@rac1 ~]# /sbin/udevadm control --reload

　　03, 诊断udev

[root@rac1 rules.d]# /sbin/udevadm test /sys/block/sdb

[root@rac1 rules.d]# /sbin/udevadm test /sys/block/sdc

[root@rac1 rules.d]# /sbin/udevadm test /sys/block/sdd

　　04,查看是否绑定成功
