ASM磁盘组剔盘、加盘实施过程

Task：从一个ASM磁盘组中剔除一块盘，加入到另一个ASM磁盘组。

环境：AIX6.1 + Oracle RAC 11.2.0.3
前期准备：
1.查看DG磁盘组空间情况：

--查看DG磁盘组空间情况： ASMCMD> lsdg State Type Rebal Sector Block AU Total_MB Free_MB Req_mir_free_MB Usable_file_MB Offline_disks Voting_files Name MOUNTED EXTERN N 512 4096 1048576 9728000 19046 0 19046 0 N DATADG/ MOUNTED EXTERN N 512 4096 1048576 3584000 1261514 0 1261514 0 N RECOVERYDG/

2.查看ASM磁盘信息：

实施步骤：

1.从RECOVERYDG磁盘组中剔除一块磁盘

2.等待同步完成

3.将磁盘加入到DATADG磁盘组

4.等待同步完成

1.从RECOVERYDG磁盘组中剔除一块磁盘

从 RECOVERYDG 剔除/dev/rhdisk38，对应信息：

512000 178001 512000 RECOVERYDG_0006 RECOVERYDG_0006 REGULAR System UNKNOWN /dev/rhdisk38
