Virtual Machine OS Upgrade causes disks to be dropped

Hello,

We have a virtual server hosted currently with OS : Windows Server 2008 R2 and when Server OS is upgraded to Windows Server 2016, We have run into a problem below:

All Non OS-Disks assigned to VM were connected on iSCSI Controller with type as Paravirtual and only OS Disk C drive is connected with another iSCSI controller with type as 'LSI Logic SAS'

OS disk and NON OS Disks were intact during server upgrade from 2008 to 2012 but the NON OS Disks were dropped from the VM during server upgrade from 2012 to 2016 and this intrun caused all the services and schedule tasks installed to the non-os disks to be removed from the system.

We have performed the activity on a cloned server. For performing the upgrade on the actual Production Server, Request suggestions on handling this scenario prior to starting the upgrade, which would help not to drop the disks after/during the upgrade.

Hey GautamRamini​,

This guy faced your same issue: https://mikeleahy.blog/2018/04/10/data-drive-missing-after-os-upgrade/ Try to re-install the VMware Tools.
