APAR Error Description / Circumvention
-----------------------------------------------
Following an IASP flashcopy, the target disks resulted in some
showing with DMP* rersources and others with DPH*. This caused
the IASP vary on to sit in DASD Checker for about 6 minutes
before moving on. The Vary On did complete and the IASP did
become Available. However when looking at the disk units, still
some were showing DPH*.
There is a very small timing window where when the DPH being
altered to DMP resources code is called, some resources may get
skipped.
Circumvention: Prior to IASP vary on a user can check the disk
resources to see if they are all showing DMP* accordingly. If
any are still showing as DPH* they can perform an IO Adapter
Reset or simply IPL the flashcopy target node and that should
allow the remaining DPH* to be converted to DMP* appropriately.
CORRECTION FOR APAR MA47940 :
-----------------------------
A race condition in the code was fixed that previously prevented
some drivers from updating from DPH to DMP.
CIRCUMVENTION FOR APAR MA47940 :

None.
