Application of this PTF may disable or render ineffective programs that
use system memory addresses not generated by the IBM translator,
including programs that circumvent control technology designed to limit
interactive capacity to purchased levels.  This PTF may be a prerequisite
for future PTFs.  By applying this PTF you authorize and agree to the
foregoing.

This PTF is subject to the terms of the 'IBM License Agreement for Machine

APAR Error Description / Circumvention

-------------------------------------------------
When an optical device is shared between IBM i partitions using
client virtual device support, and one of the IBM i partitions
modifies the contents of the optical volume, then the other
partitions can not use the volume until the partition that
modified the volume has varied the optical device description
off and back on.

An attempt by the other partitions to use the modified optical
volume will fail with MSGOPT1504 "Optical device is empty" or
MSGOPT1330 "Optical volume not found or not usable." The Work
with Optical Volumes (WRKOPTVOL) command will not show the
modified optical volume.

CORRECTION FOR APAR 'MA49190' :
-------------------------------
This fix will change the behavior as follows:

While a volume is actively being modified by one of the
partitions, then any other partition attempting to use the
volume will now receive MSGOPT1790 "Operation not allowed or
conflicts with another request" with reason code 9.

Five seconds after a partition has finished modifying/using the
optical volume all of the using partitions will be automatically
notified that the volume contents have been modified and the
volume will be freed for use, so it will no longer be necessary
to vary off/on the optical device description from the partition
that modified the optical volume before the other partitions can
use the volume. If needed, varying off/on the optical device
description on the partition that modified the optical volume
will allow it to be used before the five second wait time.

If any attempt is made to use the modified volume before the
automatic notification that the volume contents were modified
has completed the operation may  fail with MSGOPT1605 "Media or
device error occurred" with an extended status beginning with
01A10A00. Retrying the operation will recover from that error.
