System, computer program product, and method embodiments for communication between a kernel operational on a storage subsystem and a key manager (KM) through a hardware management console (HMC) to provide encryption support are provided. In one embodiment, pursuant to a data request by the kernel to the KM, data including a data payload is sent by the KM to the kernel to provide encryption support, the data payload corresponding to an event flow suborder type selected by the kernel for an event flow.

Communication between key manager and storage subsystem kernel via management console

System, computer program product, and method embodiments for communication between a kernel operational on a storage subsystem and a key manager (KM) through a hardware management console (HMC) to provide encryption support are provided. In one embodiment, an event request is initiated by the kernel to the KM to execute an event flow. Pursuant to a communication request by the kernel to the HMC, a socket of the HMC is opened along a communication path between the KM and the kernel according to an event flow type selected by the KM for the event flow. Data including a data payload is sent by the KM to the kernel, the data payload corresponding to the selected event flow type.

Communication between key manager and storage subsystem kernal via management console

Storage segments in a storage volume coupled to a cache memory are released and re-allocated. A processor receives notice to release a segment allocated to the storage volume. A release pending status is assigned to the segment while preparing the segment for release. The storage volume is enabled to re-claim the segment while the segment includes the release pending status.
