Provided are a method, system, and article of manufacture for managing encryption for volumes in storage pools. At least one storage pool is defined in a database, wherein storage pools are defined to include a plurality of data volumes, wherein each volume is included in at least one storage media. An encryption status is indicated for storage pools indicating whether encryption is enabled for the storage pool. An encryption key is provided for volumes included in storage pools for which encryption is indicated as enabled. The encryption keys for volumes included in the storage pools for which encryption is enabled are stored. The database associates the encryption keys with the volumes and the volumes with the storage pools.

Managing encryption for volumes in storage pools

Provided is a method for transferring data among a logical layer, physical layer, and storage device. The logical layer allocates a buffer to use to write data to a storage device. The physical layer manages access to the storage device. The logical layer determines an offset into the buffer based on a length of a physical header written by the physical layer and writes data to the buffer from the determined offset. The physical layer writes physical header information, wherein the physical header information does not extend past the offset in the buffer. The physical layer transfers content from the buffer to the storage device.
