How to Change Disk Status From Reserved to Online on Windows

I took a clone backup for windows failover cluster system from vmware system which used raw disks. Raw disks automatically converted to vmdk disk via vmware. I restored this clone backup as new standalone server. I started system but my disks were reserved status and I could not use these. I implemented below steps to convert disk status from reserved to online.
