APAR Error Description / Circumvention

-----------------------------------------------
Configured storage LUNs on V7000 were expanded from 80 GB to 150
GB and during the IPL to finish the LUN expansion, the system
terminated with
1 SRCB6005121
2 SRC0D200061
3 SRC0002000A
4 SRC00100011
All following IPLs would also fail nearly immediately after
reaching command line. The main storage dumps show failing task
SMFSMAPTASK with the following stack -

McTerminateImmediate+0x130C
McTerminateImmediate+0x1648
McTerminateMachine+0xD0
SmService+0xD8

CORRECTION FOR APAR MA48261 :
-----------------------------
The stack size for task SMFSMAPTASK has been increased so it no
longer causes the system to terminate.

CIRCUMVENTION FOR APAR MA48261 :
--------------------------------
None.
