We have EMC CLARiiON disks that are near their end of support, so we need to move Oracle ASM disks to a new sets disks. We are trying to minimize the database down time, so I am trying to find ways to use ASM mirroring or disk clone method to move current databases on ASM old disks to new ones.
If our databases were on the file system, we could use the disk mirror/clone to copy the data files on the file system to new disks. We could then open the database on new disks with ease. But Oracle ASM disks are different than file systems.
Any suggestions or references will be very much appreciated.
