1 Flex Copy XP overview
HP StorageWorks Flex Copy XP creates point-in-time copies from an XP array to an external array and from
an external array to an XP array.
If you copy data between the local array and an external array, you can, for example, gather data from
multiple arrays to one local array and compile the data. Then you can distribute the compiled data back
to the original arrays.
You can also use Flex Copy XP to easily back up data in the local array to other arrays and restore the
backed up data to the local array.
NOTE: You cannot access an external LU mapped for Flex Copy XP operations from the host connected to
the local array. You can set the host I/O suppression mode (enabled only for Flex Copy XP operations or
disabled for other operations) when mapping an external LU as an internal LU. For more information
about mapped volume attributes, see the HP StorageWorks External Storage XP user guide.
Flex Copy XP has the following features:
• After mapping an external LU as an internal LU using External Storage XP, you can use Flex Copy XP
to copy data from an external storage array (external LU) to the local array volume.
For instance, you can easily migrate data to the local array when removing the external array by
copying all data in the external LUs to the local array volumes.
• After mapping an external LU as an internal LU using External Storage XP, you can use Flex Copy XP
to create a copy of the local array volume in the mapped external LU.
You can make copies of data in the local array on the external LUs as if the copies were created on the
internal LUs.
Figure 1 shows the concept of copying data in external LUs to the local array volumes. In Figure 1 ,
volume A in the external array is mapped as an internal LU in the local array. In addition, data in
volume A is copied to the local array volume using Flex Copy XP.
