| Question |
| How to configure DX director in VMAX for FTS ? |
| Answer |
| referred to as DX, (for DA eXternal) has been developed that adapts the traditional DA emulation model to act on external logical units as though they were physical drives. The fact that a DX is using external LUNs instead of a DA using internal LUNs is transparent to other director emulations and to the Enginuity infrastructure in general. With respect to most non-drive-specific Enginuity functions, a DX behaves the same as a DA. ex : symsan -sid 453 list -sanports -DX 7F -port 0 >symsan list -sanluns -sid 453 -DX 7F -port 0 -wwn 50060E8005426D05 >symdisk -sid 453 show -wwn 5235303020303030313730303530303233303420 >symdisk list -dskgrp_summary -external -sid 453 before the LUN should present and diskgroup from extenral stg |
