APAR Error Description / Circumvention

-----------------------------------------------
This PTF fixes an issue resulting in MSGCPDB1AD RC'104' which is
logged when the NWSD is unable to be varied on.

During the error recovery of an iSCSI Target connection timeout,
LIC Log 4E00 0009 may be logged due to a the failed handling of
a closed connection when trying to handle data transfer.

CORRECTION FOR APAR MA39358 :
-----------------------------
When a connection times out or closed during the processing of
SCSI writes and reads, the code does not verify that the
connection is open and active before calling functions requiring
the connection to be still active.  Code will be modified to
check before trying to call these functions.
The v6r1m0 and v6r1m1 PTFs will include support for disabling
digests on Qlogic initiators.

CIRCUMVENTION FOR APAR MA39358 :
--------------------------------
None.
