Issue this command to add a client node to a collocation group or to add a file space from a node to a collocation group. A collocation group is a group of nodes or file spaces on a node whose data is collocated on a minimal number of sequential access volumes.
To issue this command, you must have system or unrestricted storage privilege.

with a name that ends with _linux_fs into the manufacturing collocation
group.define collocmember production Win_3419 filespace=* codetype=unicode
This
example command adds all file spaces from the Win_3419 node to the
production collocation group. The default is BOTH, so the file spaces
are included, regardless of code page type. You can specify one of
the following values:define collocmember group1 node1,node2
define collocmember TSM_alpha_1 clifton filespace=CNTR90524
