The correct order of steps to migrate from an old array to a new one without disruption using VPLEX is:
* VPLEX discovers the new array and the admin creates migration target devices.
* VPLEX admin initiates mobility job(s).
* Once volumes on the new array are fully synchronized, the admin commits the migration.
* VPLEX admin monitors progress of the migration; I/O to host continues.
* Connect new storage array to VPLEX.
* Discovery and Creation: The initial step involves VPLEX identifying the presence of a new storage array within its environment. Following this discovery, a system administrator is responsible for setting up migration target devices on this newly recognized array.
* Initiation of Mobility Jobs: Subsequently, a system administrator must initiate mobility jobs through the VPLEX management interface, which facilitates data movement from the existing source storage to the target devices on the new array.
* Synchronization and Commitment: After initiating mobility jobs, data synchronization between source and target arrays begins automatically. Once synchronization reaches completion, indicating that both arrays have identical data sets, an administrator must commit to finalizing this stage of migration.
* Monitoring Migration Progress: Throughout this process, it's crucial for an administrator to monitor ongoing operations ensuring that input/output operations continue uninterrupted for hosts accessing data during transition phases.
* Connecting New Array: The final step involves integrating the newly populated storage array into production by connecting it with VPLEX systems thus completing migration.

The correct order of steps to create a virtual volume is:
* Claim storage volume
* Create extent
* Create device
* Create virtual volume
* Claim Storage Volume: The first step involves claiming a storage volume from the underlying storage array. This is where you identify and allocate the physical storage that will be used.
* Create Extent: Once the storage volume is claimed, the next step is to create an extent. An extent is a specific range of block addresses within a storage volume.
* Create Device: After creating an extent, you then create a device. A device in VPLEX terminology is a logical representation of storage that can be used by hosts.
* Create Virtual Volume: The final step is to create a virtual volume from the device. A virtual volume is what is presented to hosts; it's the logical unit that they will access for storage.
This process ensures that storage is properly allocated and managed within the VPLEX environment, allowing for flexibility and efficiency in storage utilization.
For detailed procedures and best practices, it's recommended to consult the official Dell VPLEX documentation and training materials, which provide in-depth guidance on managing and configuring VPLEX systems.
