I have a client with an HSG80 SAN with OpenVMS(7.3-1) and Windows 2000 hosts. All hosts are single attached and no zoning on the switches. I would like to implement zoning in their fabric and I know on HP-UX hosts this can cause device ID's to shift. Is this also the case with OpenVMS? I have limited Unix knowledge so any help is appreciated.<BR /> <BR /> Thanks.<BR /> Dave Wed, 02 Nov 2005 23:39:33 GMT https://community.hpe.com/t5/msa-storage/san-question-with-vms/m-p/586110#M1702 CA972086 2005-11-02T23:39:33Z https://community.hpe.com/t5/msa-storage/san-question-with-vms/m-p/586111#M1703 HP-UX uses the target's N_PortID to build the hardware path.
