The customers of Dell EMC PowerEdge servers typically create Virtual Drives (VDs) and then install applications and/or operating systems (OSs), on these VDs. Over time it is possible that these VDs are not able to meet the increasing storage capacity and/or redundancy requirements of an application. With earlier generations of iDRAC, customers required to have a system down-time to migrate these applications to the new VDs that have higher capacity and different RAID level to meet the expectations of the application.
This technical white paper describes a method to increase the capacity of an existing VD while it is Online (no system down-time). It also enables customers to change the drive failure tolerance (which is decided by the RAID level of a VD) of an Online VD by changing its RAID level.
