RE: ASM "disk" replacement

I've considered this and it is the other option.  The downside is
downtime.  Supposedly, this can be done in ASM via the "disk" shuffle
with none.

Just wondering - WARNING - from the top of my head.

Since ASM sees the mount point only, it does not care about the physical
disks in the storage why not use the storage facilities to do the copy?

1) create a storage snapshot that duplicate the old disks to the new
disks and wait for the storage copy to finish.
2) bring down the database and severe the connection between the
original disks and the snapshot.
3) switch the mount point to point to the snapshot.
4) bring up the database.

Take with a TON (not a grain) of salt.
