We have EMC CLARiiON disks/storage arrays that are near their end of support life cycle, so we need to move Oracle ASM disks on them to a new sets of vendor 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 to new ASM disks with underlining new disks/storage arrays.
If our databases are on the file system, we can use the disk mirror/clone to copy the datafiles on the file system to new disks. We can 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.
