APAR Error Description / Circumvention

-------------------------------------------------
When multiple tape I/O paths fail at or near the same time it is
not always possible to successfully complete fail-over to a new
operational path.

CORRECTION FOR APAR 'MA44958' :
-------------------------------
Apply this fix to improve the tape I/O path fail-over processing
for complex failure scenarios.

CIRCUMVENTION FOR APAR 'MA44958' :
----------------------------------
None.

DESCRIPTION OF PROBLEM FIXED FOR APAR 'MA45045' :
-------------------------------------------------
An install of XPF from tape will wait at SRCC6004065 if the tape
drive is not multipath capable.
Multipath is only supported for Fibre channel attached LTO5 and
later, 3592-E07 and later, and ProtecTIER drives.
All other tape drive types or attachment types will fail.

CORRECTION FOR APAR 'MA45045' :
-------------------------------
Apply this fix to allow proper install from a non-multipath
capable tape drive.

CIRCUMVENTION FOR APAR 'MA45045' :
----------------------------------
None.


Activation Instructions


None.




Special Instructions

To ensure that an install from tape will work properly, the system
should be saved after applying this fix.


Default Instructions

THIS PTF CAN BE APPLIED IMMEDIATE OR DELAYED.
