APAR Error Description / Circumvention

-----------------------------------------------
When performing concurrent maintenance on a failed I/O expansion
drawer or cables, devices can fail to recover.  For example, an
Exchange FRU operation can fail with return code 300.  A Dynamic
Logical Partitioning remove operation and a native IBMi (green
screen) slot power off can also be affected.

CORRECTION FOR APAR MA48499 :
-----------------------------
When devices fail to deactivate because a PCIe slot is frozen,
the code will not release resources such as interrupts.  This
can lead to an error message and prevent the concurrent
maintenance operation from completing.

This is only a problem with on Power9 servers.  Only storage
controllers are known to be affected.  Communications cards,
cryptography cards, and USB controllers are not affected.
Partitions at disk unit attention (e.g. SRCA6000255 or
SRCA6000266) are typically not exposed to this problem.

CIRCUMVENTION FOR APAR MA48499 :
--------------------------------
None.
