We can say it clones the same files at new host. vmdk file exactly the RDM disk files at destination host. When migrating RDM files, It creates a new. However, RDMs files do not move automatically because it is physical storage but pointer file (RDM) can be reallocated to destination host. If you are migrating the VM files also, All non-RDM VMs files will move to destination host including virtual machine configuration file. In cold migration, virtual machine needs to be shutdown. It does not require any downtime on the virtual machine. When you do the vMotion of the virtual machine, It just moves the compute resources from the current host to destination without affecting the RDMs and disk files. Storage Migration (Storage vMotion), with the virtual machine powered on.Cold Migration, with the virtual machine powered off.Warm Migration (vMotion), with the virtual machine powered on.Migrating a virtual machine with RDMs can be done either three ways: Remove the device that has an issue from all the ESXi hosts on the cluster temporarily.If they are doing the datastore expansion, abort your migration. Let the support team know about the activity.To prevent the data loss you can do the following things: This way you can avoid any unnecessary outage.Īlso if you are removing the RDM from the virtual machine during the datastore expansion, you might lose the data from the disk associated with the virtual machine. You should involve support team to fail-over the resources from the node you are going to migrate. ![]() ![]() If the hardware version is greater than 10, VMs can be migrated without shutting down it but if the hardware version is less than 10, It needs to be shutdown. ![]()
