Created: 03 Aug 2012 | 1 comment

Hello,

I have a situation where i need to mirror a 0+1 (similar to above) volume to a single SAN disk.

are there any constraints/consideration to make before i go with mirroring?

configuration:

 

v  ora00    -            ENABLED  ACTIVE   286615666 SELECT   ora00-04 fsgen

pl ora00-04 ora00    ENABLED  ACTIVE   286615808 STRIPE   2/128    RW

Hi,

should not be a constraint ...  you can simply do it using vxassist command .... only thing to make sure is, you have same or more size of disk ...

# vxassist -g <diskgroup> mirror <vol> <new_SAN_disk>

if you want, you can specify additional layout if any, else above command should simply mirror it with single disk ...
