How to rename ASM diskgroups after having cloned the original disks to the same server. ASMlib is us

massiminoAug 27 2014 — edited Sep 12 2014

Linux RHE 6

Oracle Grid single instance (Oracle Restart) 11.2.0.4 installed

Oracle RDBMS 11.2.0.4 installed

One 11.2.0.4 database single instance running

Our ASM have DATA, REDO, FRA diskgroup mounted

We need to do a storage snapshot for creating on THE SAME server a copy of the current ASM diskgroups DATA, REDO, FRA. Then we would rename the cloned diskgroups using renamedg command.

We have done this operation several times when ASMlib is not used. The command used when ASMlib is not used is for example:

renamedg dgname=FRA newdgname=FRA2 verbose=true phase=both asm_diskstring='/dev/oracle/fra*'

With ASMlib in use I am not sure about the steps to follow

First I am not sure about what to provide to the asm_diskstring parameter of the renamedg command. I need to provide an asm_diskstring which identifies the path pointing to the disks belonging to the cloned diskgroup (I do not want to rename the original diskgroup). Though in an ASM instance using ASMlib the parameter asm_diskstring is is ‘ORCL:*’.

Second, I suppose after the diskgroup rename ASMlib would return an error because it would find duplicated disks.

Could you please advise ?

Thanks in advance

Massi
