Abstract
A method is used in managing accesses to active-active mapped logical volumes. A portion of a mapped logical volume associated with an I/O request is determined. Based on the determination, a set of storage processor paths for accessing the mapped logical volume is determined. The I/O request is sent using a storage processor path from the set of storage processor paths for accessing the mapped logical volume.
