Issue:
VPLEX Device mapping failed for device:device_X with error: Device:device_X extent:extent_X is not 1:1 created on storage volume:X and is not supported by AppSync.
Cause:
AppSync only supports VPlex volumes which were created using the full capacity of a storage-volume.
Only fully encapsulated VPLEX volumes are supported by AppSync.
Change:
Resolution:
The following steps are to be performed on the VPlex. In the following troubleshooting procedure, a fictitious local virtual-volume, 'device_Symm1000_00AB_1_vol' is used as an example.
1. Login to the VPlexcli and perform a 'show-use-hierarchy' against the VPlex virtual-volume of interest; VPlexcli:/> show-use-hierarchy -t /clusters/cluster-1/virtual-volumes/device_Symm1000_00AB_1_volstorage-view: VPLEX_STORAGE_VIEW (cluster-1) virtual-volume: device_Symm1000_00AB_1_vol (2T, local @ cluster-1, running) local-device: device_Symm1000_00AB_1 (2T, raid-0, cluster-1) extent: extent_Symm1000_00AB_1 (2T) storage-volume: Symm1000_00AB (2T) logical-unit: VPD83T3:60000970000196801000533000000111 storage-array: EMC-SYMMETRIX-196801000
2. Note that the virtual-volume is 1:1 mapped: virtual-volume to storage-volume.
VPlexcli:/> show-use-hierarchy -t /clusters/cluster-1/virtual-volumes/device_Symm1000_003B_1_volstorage-view: VPLEX_STORAGE_VIEW (cluster-1) virtual-volume: device_Symm1000_00AB_1_vol (2T, local @ cluster-1, running) local-device: device_Symm1000_00AB_1 (2T, raid-0, cluster-1) extent: extent_Symm1000_00AB_1 (2T) storage-volume: Symm1000_00AB (2T) logical-unit: VPD83T3:60000970000196801000533000000111 storage-array: EMC-SYMMETRIX-196801000
3. If the virtual-volume reports, 'expandable by X' where X is the respective size, then AppSync will report this volume as not 1:1 mapped due to the extent not consuming the entire storage volume.
VPlexcli:/> show-use-hierarchy -t /clusters/cluster-1/virtual-volumes/device_Symm1000_003B_1_volstorage-view: VPLEX_STORAGE_VIEW (cluster-1) virtual-volume: device_Symm1000_00AB_1_vol (2T, local @ cluster-1, running, expandable by 2M) local-device: device_Symm1000_00AB_1 (2T, raid-0, cluster-1) extent: extent_Symm1000_00AB_1 (2T) storage-volume: Symm1000_00AB (2T) logical-unit: VPD83T3:60000970000196801000533000000111 storage-array: EMC-SYMMETRIX-196801000
In this case, please follow VPLEX: How to Expand a virtual volume in-order to expand the virtual-volume's underlying components and the virtual-volume itself to utilise it's full capacity.
