FlashCopy function (for Windows only)
Note: The ServeRAID-5i controller does not support the FlashCopy function.
The FlashCopy function creates a quick backup copy of data. It sets up a link
between the source and target partitions; then, it creates a snapshot-like backup of
the source data on the target partition. Any changes made to the source drive after
you issue the command are not reflected on the target drive; the target drive is
instantly available for access. You can use the backup copy of data for such tasks
as tape backup, drive cloning, and multiserver rollout.
There are two primary FlashCopy functions: backup and nobackup. The FlashCopy
backup function copies the entire contents of the source partitions to the target
partitions so that entire logical drives can be moved from one server to another. The
FlashCopy nobackup function creates a temporary snapshot copy of a partition for
tape drive backup and reference purposes. The FlashCopy nobackup function is
less I/O-intensive than the FlashCopy backup function.
Other FlashCopy functions include the following:
v delete : You can use this function to delete an array.
v import : After a FlashCopy backup function is completed, you can use this
function to move a logical drive to another server.
v map : You can use this function to determine the partition numbers and whether
they are available for the FlashCopy backup or nobackup processes.
v stop all : You can use this function to break the links between the source and
target partitions.
