Hi All, Again after a gap of few months back again with a quick post on "How to create & attach shared disks on multiple VMs in VirtualBox). Shared storage is one of the primary requirements for implementing Oracle Real Application Clusters. The code snippet shows how to : 1) List the existing HDDS 2) Create a shared HDD (In shareable mode) 3) Attach the newly created HDDs to multiple VMs Note:- VBoxManage.exe is the executable that helps us in command line for carrying out tasks in VirtualBox.
