Though existing KB says no consequence to Solaris

Not specific to S/E but seems possibly related.

I think you should look into Dynamic Lun Addressing, not device offset.
See the Technote "Symmetrix Dynamic LUN Addressing" available on http://powerlink.emc.com
Navigate as follows:
Home > Support > Technical Documentation and Advisories > Hardware/Platforms Documentation > Symmetrix DMX Family > Symmetrix DMX-3 > Technical Notes/Troubleshooting >

Or, go directly to the above ref. doc at

I'm sure there are other uses though, haven't read up on it in a while.

DLA replaces the good old lun offset trick thus you probably don't need lun offset.

so I believe if we set the DLA for a wwn we must always use DLA for that wwn.
but we have storage provisioned from multiple symm and their LUN address have not reached 256.
how do we reclaim this dev which has provisioned to host as DLA. Is it same as normal un masking?
