Migrating virtual machines across commonly connected storage providers

Abstract:

Method and system for deploying a virtual machine or attaching a storage volume to a virtual machine (VM). A process obtains information regarding fabrics attached to hosts and storage devices attached to the fabrics and determines whether a VM can be deployed to a host or whether storage volumes can be attached to a VM. In one case, determining that a fabric attached to a host can support a virtual SCSI volume causes migrating a VM to the host and attaching the virtual SCSI volume to the migrated VM. In another case, determining that the fabric attached to a host can support an NPIV volume causes migrating the VM to the host and attaching the NPIV volume to a virtual channel mapped to the fabric attached to the host. If the VM cannot be migrated, then the user is given an indication that the attachment is not possible.
