No can do, disk mobility within the same array is available in VNX2 only.
This question must have been asked before but i cannot find the answer. If i have 2 VNX 5300 storage systems with the same VNX OE; can i move all disks in a storage pool to the other VNX  and get the same pool and LUN's back in the other VNX ? If this can be done i probably need to shutdown both VNX systems and move the physical disks from the one system to the other ?
Move storage pool between VNX systemen
