今天是2014-03-24，介绍一个重命名oracle asm 磁盘组的工具renamedg
The renamedg tool enables you to change the name of a cloned disk group. The disk group must be dismounted on all nodes in the cluster before running renamedg on the disk group.
renamedg renames a disk group using a two-step process:
Phase one
This phase generates a configuration file to be used in phase two.
Phase two
This phase uses the configuration file to perform the renaming of the disk group.
The syntax is:
renamedg {-help | help=true}
renamedg
[phase={ one|two |both } ] dgname=diskgroup
newdgname=newdiskgroup [config=configfile]
[ asm_diskstring=discoverystring, discoverystring ... ]
[ clean={true|false} ] [ check={true|false} ]
[ confirm={true|false}] [ verbose={ true|false} ]
[ keep_voting_files={true|false}]
-
phase={one|two|both}
