APAR Error Description / Circumvention

-----------------------------------------------
When Dynamic Logical Partitioning (DLPAR) is used to remove a
PCI adapter/device immediately after being added, the Hardware
Management Console (HMC) may report a failure.  Likewise
Hardware Service Manager screens may report that the adapter is
disabled.  Further attempts to add or remove adapters in the
same slot may also fail.

CORRECTION FOR APAR MA47943 :
-----------------------------
When background tasks are still bringing up an adapter after a
DLPAR add, a DLPAR remove may not remove all adapter resources,
such as MMIO.  When the Converged Hypervisor detects this
problem, it will prevent future DLPAR adds in that slot.  A
DLPAR remove now checks when a DLPAR add is still in progress
and waits until background tasks are complete before removing
resources.

CIRCUMVENTION FOR APAR MA47943 :
--------------------------------
If a user wishes to DLPAR remove an adapter after DLPAR adding
it, Hardware Resource Manager should be used to verify that all
resources in that slot report an Operational status before DLPAR
removing it.
