浪子归家|Oracle数据盘扩展-ASM 12345更多下一页--

概述：
本次演示asm的数据盘的增减，长篇大论不是我的风格，实际操作步骤如下：
1、本地硬盘操作
a、添加硬盘，信息如下
Disk /dev/sdg: 1073 MB, 1073741824 bytes34 heads, 61 sectors/track, 1011 cylindersUnits = cylinders of 2074 * 512 = 1061888 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0x00000000b、查看磁盘UUID：

[root@bpmdb /]# /sbin/start_udevStarting udev: [OK]f、确认绑定磁盘
[root@bpmdb /]# ls -l /dev/asm*brw-rw---- 1 grid asmadmin 8, 16 Jul 31 08:52 /dev/asm-diskbbrw-rw---- 1 grid asmadmin 8, 32 Jul 31 08:52 /dev/asm-diskcbrw-rw---- 1 grid asmadmin 8, 48 Jul 31 08:52 /dev/asm-diskdbrw-rw---- 1 grid asmadmin 8, 64 Jul 31 08:52 /dev/asm-diskebrw-rw---- 1 grid asmadmin 8, 80 Jul 31 08:52 /dev/asm-diskfbrw-rw---- 1 grid asmadmin 8, 96 Jul 31 08:52 /dev/asm-diskg2、ASM扩展步骤
a、查看asm磁盘组
select GROUP_NUMBER,NAME,TOTAL_MB,FREE_MB from v$asm_diskgroup;
