On a somewhat related note, be careful, the new default for collcation when
creating a new storage pool is "GROUP". With V5.2 and earlier it was "NO". Now
with V5.3 it is effectively "NODE" until you create your first group as Andy
mentions.

Geoff,
You get collocation by node.
If you look up the syntax for DEFINE STGPOOL, you'll see some text for the
COLLOCATE option that hints at this:
----------
If you specify COLLOCATE=GROUP but do not define any groups, data is
collocated by node. Similarly, if you specify COLLOCATE=GROUP and you
define a group but do not add nodes to the group, data is collocated by
node.
----------
with the theme being that nodes not in a group are collocated by NODE when
the storage pool's COLLOCATE setting is GROUP.

Andy
