Abstract:
In an embodiment, a power off command is received that specifies a slot in a computer that connects to a first adapter. The first adapter comprises a physical and virtual functions. Data transfer from a logical partition to the virtual function is stopped, a lock of the virtual function held by the logical partition is released, and the slot is powered off. Ownership of the virtual function is retained by the logical partition while the lock is released and the slot is powered off. A power on command is received that specifies the slot that connects to a second adapter. The second adapter comprises the physical and virtual functions. In response to the power on command, the slot is powered on, and the lock is obtained of the virtual function for the logical partition.
