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}]

  1. phase={one|two|both}

    注意:

     

    Applies to:
    Oracle Server - Enterprise Edition - Version: 10.1.0.2 to 11.2.0.0
    Information in this document applies to any platform.

    Goal
    The purpose of this document is to provide information about rename diskgroup in 10g and 11gR1 release

    Solution
    rename diskgroup option is a new feature of 11gR2 .

    You can use this tool to rename your 10g or 11gR1 ASM diskgroup

    you need to just install 11gR2 SIHA Grid Infrastructure software only installation.

    cd /bin
    renamedg

    use renamedg tool to rename 10g or 11gR1 diskgroup.

    Diskgroup cannot be renamed under following conditions :

    - the Diskgroup is mounted
    - the Diskgroup is being used by CSS
    - Diskgroup contains offline disks

    eg:

    -bash-4.1$ sqlplus / as sysasm
