Dears,  For migration purpose [from IBM to DMX array], I have mapped/masked the AIX host HBAs to both IBM and DMX arrays. The host is currently attached to IBM and using data path [vpath] multipathing software of AIX.  And, for DMX devices, I am planning to install power path multipathing software.  Now the concern is  -whether powerpath will be used only for DMX luns OR even for existing IBM LUNs.   - If only be used to access DMX devices, it should be fine. -  Is there anyway I can configure power path only for DMX LUNs not disturbing existing vpath to IBM LUNs?  I prefer not to disturb the existing vpath and configure power path only to DMX luns  Please share your expertise   cheers [IMAGE]
