Using Dynamic Multi-Pathing (DMP) devices with Oracle Automatic Storage Management (ASM)

DMP supports Oracle ASM. You can:

  • Enable DMP devices for use with Oracle ASM—Make DMP devices visible to ASM as available disks to enable their use with Oracle ASM. DMP support for ASM is available for char devices (/dev/vx/rdmp/*). 
    For more information, see Enabling DMP devices for use with Oracle ASM.
  • Migrate Oracle ASM disk groups from operating system devices to DMP devices—If an existing ASM disk group uses operating system native devices as disks, you can migrate these devices to DMP control. If the OS devices are controlled by other multi-pathing drivers, this operation requires system downtime to migrate the devices to DMP control. 
    For more information, see Migrating Oracle ASM disk groups from operating system devices to DMP devices
  • Remove DMP devices from the listing of Oracle ASM disks—Remove DMP devices from the listing of ASM disks by disabling DMP support for ASM from the device. You cannot remove DMP support for ASM from a device that is in an ASM disk group. 
    For more information, see Removing DMP devices from the listing of Oracle ASM disks.
