标题: 重启操作系统后无法看到asm磁盘
现象：重启操作系统后，集群无法启动磁盘组资源。

手工启动失败
[grid@hisdg ~]$ srvctl start diskgroup -g DATA
PRCR-1079 : Failed to start resource ora.DATA.dg
CRS-5017: The resource action "ora.DATA.dg start" encountered the following error:
ORA-15032: not all alterations performed
ORA-15017: diskgroup "DATA" cannot be mounted
ORA-15063: ASM discovered an insufficient number of disks for diskgroup "DATA"

查看磁盘组，发现无显示
[root@hisdg ~]# oracleasm listdisks

扫描磁盘成功
[root@hisdg ~]# oracleasm scandisks

分析：在配置磁盘权限时，未启用重启服务器时扫描磁盘功能
[root@hisdg ~]# oracleasm configure -i
Configuring the Oracle ASM library driver.

This will configure the on-boot properties of the Oracle ASM library
driver.  The following questions will determine whether the driver is
loaded on boot and what permissions it will have.  The current values
will be shown in brackets ('[]').  Hitting <ENTER> without typing an
answer will keep that current value.  Ctrl-C will abort.

Default user to own the driver interface [grid]: grid
Default group to own the driver interface [asmadmin]: asmadmin
Scan for Oracle ASM disks on boot (y/n) [n]: y
Writing Oracle ASM library driver configuration: done
