Abstract
An OS instance can maintain management responsibility for SAN adapters to ensure separation and isolation of WPARs, while WPARs are given the capability of configuring an adapter (e.g., adding endpoint storage devices to the adapter). An operating system instance allocates an adapter to a first of a plurality of virtual operating system instances. The first virtual operating system instance updates a device data structure with an entry that indicates the adapter. The first virtual operating system instance maintains the device data structure. The first virtual operating system instance modifies the entry in the device data structure to associate a set of one or more endpoint storage devices with the adapter. The set of endpoint storage devices are provisioned to the first virtual operating system instance from a storage area network. The first virtual operating system instance configures the set of endpoint storage devices.
