Local fix
Problem summary
I/O may hang when a DS3K, DS4K, or DS5K LUN is unmapped with newer storage microcode levels, and running AIX default MPIO PCM.
Problem conclusion
Field necessary for handling LUN unmapping has shifted in newer microcode levels of DS3K, DS4K, or DS5K. For newer microcode levels, retrieve necessary field from new offset. Older microcode levels, will still use previous offset.
Temporary fix
