如何重命名ASM 中的磁盘组 - 数据库编程

Therenamedgtool enables you to change the name of a cloned disk group. The disk group must be dismounted on all nodes in the cluster before runningrenamedgon the disk group.

renamedgrenames a disk group using a two-step process:

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}]

注意：

eg：

-bash-4.1$ sqlplus / as sysasm

SQL*Plus: Release 11.2.0.4.0 Production on Mon Mar 24 15:33:16 2014

Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production
With the Automatic Storage Management option

SQL> alter diskgroup new_datagroup2 dismount;

Diskgroup altered.

-bash-4.1$
-bash-4.1$ renamedg -help
NOTE: No asm libraries found in the system

Parsing parameters..
phase Phase to execute,
(phase=ONE|TWO|BOTH), default BOTH

dgname Diskgroup to be renamed

newdgname New name for the diskgroup

config intermediate config file

check just check-do not perform actual operation,
(check=TRUE/FALSE), default FALSE

confirm confirm before committing changes to disks,
(confirm=TRUE/FALSE), default FALSE

clean ignore errors,
(clean=TRUE/FALSE), default TRUE

asm_diskstring ASM Diskstring (asm_diskstring='discoverystring',
'discoverystring1' ...)

verbose verbose execution,
(verbose=TRUE|FALSE), default FALSE

keep_voting_files Voting file attribute,
(keep_voting_files=TRUE|FALSE), default FALSE

-bash-4.1$ renamedg dgname=NEW_DATAGROUP2 newdgname=datagroup2 asm_diskstring='/dev/oracleasm/disks/*' verbose=true
