Azure VMS Use the D: disk as a data drive on a Windows VM

Source: Internet
Author: User

If your application needs to use the D drive to store data, follow these instructions to use a different drive letter as a temporary disk. Never use a temporary disk to store the data you want to save.

If you resize the virtual machine or stop (DEALLOCATE) The virtual machine, this may trigger the operation of placing the virtual machine in the new hypervisor. A scheduled or unplanned maintenance event may also trigger this drop operation. In this scenario, the temporary disk is reassigned to the first available drive letter. If the application explicitly requires a D: disk, you will need to follow these steps to temporarily move the Pagefile.sys, connect the new data disk and assign it a drive letter D, and then move the Pagefile.sys back to the temporary drive. When you are done, Azure does not retract D: If the VM is moved to a different hypervisor.
