Abstract: A technique operable in a data storage system performs initialization of storage structures in multiple stages and allows hosts to request access to a data object even when some of the storage structures supporting the data object have not been initialized.

The further processing includes, in response to receiving a protocol request directed to a host-accessible data object, identifying storage structures involved in processing that protocol request and directing the storage processor to initialize those storage structures.

In response to the primary management device failing, the secondary management device determines the desired fan speed based on the profile and set the fan speed to the desired fan speed that it determined.
