IBM SDD only manages luns which reside on the IBM storage. if you have
additional luns which reside on another brand of storage, they are not
affected by SDD.
however, in order to use SDD you have to set NW multipath support to
off, so you have to use another method to use multipath support on the
other brand's storage.
we encountered this when moving our NW storage from IBM DS6X00 to EMC.
eventually we ended up migrating with single paths towards both storage
systems. after the migration we installed EMC powerpath.

btw, i wish you all the luck using SDD on netware. we never succeeded in
getting it to work properly.
