A cache tier device experiences a permanent disk failure.

Which of the below represents a valid process for replacing the failed disk?

A. 1. The

hot spare disk replaces the failed disk immediately.

2. Physically replace the failed disk.

B. 1. Using the vSphere Web Client, replace the failed disk with the hot spare disk.

2. Physically replace the failed disk.

C. 1. Using the vSphere Web Client, dele

te the failed disk from the vSAN cluster.

2. Physically replace the failed disk.

3. Using the vSphere Web Client, re-create the disk group.

D. 1. Physically replace the failed disk and vSAN automatically takes of the rest of the process.

Explanation:

When a flash device failure occurs, before physically removing the device from a host, you must decommission the device from Virtual SAN. The decommission process performs a number of operations in order to discard disk group memberships, dele

tes partitions and remove stale data from all disks.

How to do it. Flash Device Decommission Procedure from the vSphere Web Client

Log on to the vSphere Web Client

Navigate to the Hosts and Clusters view and select the cluster object

Go to the manage tab

and select Disk management under the Virtual SAN section

Select the disk group with the failed flash device

Select the failed flash device and click the delete button
