A company has VPLEX Metro protecting two applications without Cluster Witness:
. App1 distributed virtual volumes are added to CG1, which has detach-rule set cluster-1 as winner
. App2 distributed virtual volumes are added to CG2, which has detach-rule set cluster-2 as winner What should be the consequence if cluster-2 fails for an extended period?

• A.I/O for CG1 is detached at cluster -1; I/O is serviced at cluster-2I/O for CG2 is detached at cluster -2; I/O is serviced at cluster-1
• B.I/O for CG1 is serviced at cluster -1; I/O is suspended at cluster-2I/O is serviced for CG2 at cluster -2; I/O is suspended at cluster-1
• C.I/O for CG1 is suspended at cluster -1; I/O is serviced at cluster-2I/O for CG2 is serviced at cluster -1; I/O is suspended at cluster-2
• D.I/O for CG1 is suspended at cluster -1; I/O is serviced at cluster-2I/O for CG2 is serviced at cluster -2; I/O is suspended at cluster-1

What is the correct order of steps to migrate from an old array to a new one without disruption using VPLEX?

Correct Answer:

Explanation:


The correct order of steps to migrate from an old array to a new one without disruption using VPLEX is as follows:
* Connect the new storage array to VPLEX.
* VPLEX discovers the new array, and the admin creates migration target devices.
* The VPLEX admin initiates mobility job(s).
* VPLEX admin monitors the progress of the migration; I/O to the host continues.
* Once volumes on the new array are fully synchronized, the admin commits the migration.
* Connect New Storage Array: The first step involves physically connecting the new storage array to the VPLEX system and ensuring proper connectivity1.
* Discovery and Device Creation: VPLEX then discovers the new array. The administrator uses the VPLEX management interface to create the target devices that will receive the data from the old array1.
* Initiate Mobility Jobs: The administrator initiates mobility jobs using the VPLEX CLI or management interface. These jobs handle the data transfer from the old array's devices to the new array's devices1.
* Monitor Migration Progress: While the mobility jobs are running, the administrator monitors the progress. During this time, the host continues to perform I/O operations without disruption1.
* Commit Migration: After the data has been fully synchronized to the new array, the administrator commits the migration. This finalizes the transfer and allows the host to use the new array's devices as if they were the original ones1.
This process ensures a smooth and non-disruptive migration from an old storage array to a new one using VPLEX, maintaining continuous availability of applications and data.
