We'll need to make sure we update the SAS reference guide to document this as a
valid state:
http://www-01.ibm.com/support/knowledgecenter/8247-22L/p8ebk/diskarraystates.htm?cp=8247-22L
What happens now if you create a single disk RAID 0 with a device not known to
be zeroed? Does this now
display the Initializing status? If so, we might want to enhance the patch
description to indicate this.
Thanks,
Brian
