Abstract: Exemplary method, system, and computer program embodiments for data migration between first and second storage mediums of an available plurality of storage mediums in a computing storage environment are provided. In one embodiment, pursuant to migrating the data from the first to the second storage medium, the data is allocated to the second storage medium while retaining an allocation of the data in the first storage medium. If the data is migrated from the second storage medium back to the first storage medium, the data is pointed to the allocation of the data in the first storage medium to alleviate data movement from the second storage medium to the first storage medium. If the allocation of the data in the first storage medium is determined to be needed for other data, the allocation of the data in the first storage medium is freed.

Abstract: Provided are a method, system, and computer program for synchronizing device error information among nodes. A first node performs an action with respect to a first node error counter for a device in communication with the first node and a second node. The first node transmits a message to the second node indicating the device and the action performed with respect to the first node error counter for the device. The second node performs the action indicated in the message with respect to a second node error counter for the device indicated in the message, wherein the second node error counter corresponds to the first node error counter for the device.

Abstract: Extent migration is provided in a data storage environment configured for synchronous replication between a primary and secondary pair of storage entities, each having tiered storage devices. In one embodiment, a migration instruction is sent, by the primary storage entity, to the secondary storage entity, the migration instruction including a relative priority based on a primary ordered heat map of the tiered storage devices of the primary storage entity. The relative priority is used against a secondary ordered heat map of the tiered storage devices of the secondary storage entity to perform the extent migration, regardless of whether the primary and secondary storage entities are identical.
