Hi Team.

Rob Jackard from the ATS Group does a great job amalgamating IBM storage site updates so I am sharing them here with you.  Here is my high level view:

AIX Users:   Review the service dates for your technology level. 
DS3500 users:   Upgrade your firmware to  7.70.45.00 or 7.77.19.00.
DS8000 users:   Take note of the limitation on resizing a space efficient repository.  I dealt with this recently at a client but writing a script to delete the flashcopy targets, delete and recreate the repositories and then create the flashcopy targets again.
SVC and Storwize V7000 users:  Upgrade to 6.1.0.9 or 6.2.0.2.  Be aware of the limitations on split cluster and Global Mirror intra-cluster mirroring.

AIX:
