Hi Ram,  The "VPD ID" of the virtual-volume is the unique identifier. It is the same as the "naa number". All logical-units presented to VPLEX will have their own VPD numbers provided by their respective arrays. VPLEX puts its own VPD number on virtual-volumes because VPLEX volumes can span multiple back end devices, e.g. RAID-1 and RAID-C and VPLEX can also carve up a single back end device into multiple extents.  The best way to view and track the architecture of a device along with the VPD IDs is the "show-use-hierarchy" command. It will accept wildcards, but will need to resolve the full path to one or more volumes.  Example: VPlexcli:/> show-use-hierarchy /**/virtual-volumes/device_RPA_LUN1_1_vol storage-view: VIPR_STORAGE_VIEW (cluster-1)   consistency-group: CG-Test1 (synchronous)     virtual-volume: device_RPA_LUN1_1_vol (10G, distributed @ cluster-1, running)       distributed-device: device_V47G_6_3PAR02_60002 (10G, raid-1)         distributed-device-component: device_V47G_6_3PAR02_600022017Nov25_230134 (10G, raid-0, cluster-1)           extent: extent_RPA_LUN1_1 (10G)             storage-volume: RPA_LUN1 (10G)               logical-unit: VPD83T3:6006016013302700d8b7b81c26aae311                 storage-array: EMC-CLARiiON-APM00100201782         distributed-device-component: test_leg_2 (10G, raid-0, cluster-2)           extent: extent_VPD83T3_6006016013302700edd0e1c80c45e011_1 (10G)             storage-volume: VPD83T3:6006016013302700edd0e1c80c45e011 (10G)               logical-unit: VPD83T3:6006016013302700edd0e1c80c45e011                 storage-array: EMC-CLARiiON-APM00100201782    There are also OS specific encapsulation procedures in SolVe  Regards,Ben
Hi all,  Would like to know what is a VPD ID in VPLEX and its uses? Also wanted to know more about Encapsulation process in VPLEX. What is the need to do it and what are its advantages? Extents.... Devices....  Would be great if there is any documentation for the same.  Thanks in advance  Ram.
