Replicating Data Off-line
You have a four-disk legacy JBOD. You want to upgrade to a new JBOD
and need to replicate the contained data from the old device to the new
device as expediently as possible. None of the disks are virtualized or
exposed. You must virtualize all of the physical disks to simple volumes
with the same capacity and block size. If the new disks are larger than the
old disks, you must first create subdisks of the same capacity as the old
disks before creating simple volumes. Then replicate the data from the old
volumes to the new volumes. When the replication is complete, you are left
with two independent data copies from each original volume.
This example explains how to:
Create simple volumes.
