Which two approaches can the vSAN administrator use to complete this task?

A vSAN administrator has been tasked to add capacity to an existing vSAN cluster and has ordered enough larger capacity devices to complete this work. Tests have been executed, and the replacement from one single capacity device will require 70 minutes.

Which two approaches can the vSAN administrator use to complete this task? (Choose two.)
A . Confirm with pre-check that enough capacity for data migration is available, select a capacity device, click "remove disk" with "Ensure accessibility", replace capacity device, claim unused device, and then repeat one-by-one.
B. "Change object repair timer to 75 minutes", "set capacity device to offline", and then replace capacity device one-by-one.
C. Enter Maintenance Mode, confirm that pre check is fine, select "Full data migration", "Shutdown ESXi host", replace all capacity devices, "Restart ESXi host", replace capacity devices in disk groups, exit Maintenance Mode, confirm that raw capacity has been increased, and then repeat on ESXi host one-by-one.
D. "Shutdown ESXi host", and replace all capacity devices. Repeat this sequence one-by-one.
E. Execute a "Data Migration Pre-Check", enter Maintenance Mode with default setting, "Shutdown ESXi host", replace all capacity devices, and then repeat on ESXi hosts one-by-one.

Answer: C,D

Explanation:

C. Enter Maintenance Mode, confirm that pre check is fine, select "Full data migration", "Shutdown ESXi host", replace all capacity devices, "Restart ESXi host", replace capacity devices in disk groups, exit Maintenance Mode, confirm that raw capacity has been increased, and then repeat on ESXi host one-by-one.

D. "Shutdown ESXi host", and replace all capacity devices. Repeat this sequence one-by-one.

Option C would allow you to perform a full data migration, which will move all data from the old capacity device to other devices. This option allows for the vSAN cluster to remain offline during the replacement process, and it allows the vSAN administrator to replace all the capacity devices at once.

Option D would also allow you to replace all capacity devices at once, however, the data is not moved from the old capacity device to other devices, this option also allows for the vSAN cluster to remain offline during the replacement process and it allows the vSAN administrator to replace all the capacity devices at once.

You can find more information on adding capacity to a vSAN cluster in the vSphere 7.0 documentation: https://docs.vmware.com/en/VMware-vSphere/7.0/vsphere-esxi-vcenter-server-70-vsphere-storage-vsan-70-upgrade-guide.pdf and also in VMware blog like: https://blogs.vmware.com/vsphere/2021/03/vsphere-7-0-update-1-vsan-7-0-update-1-general-availability.html
