Perform the following steps to enable multipathing on all multipath-capable devices on SPARC or x86 based systems. If you want to enable multipathing only on specific FC or SAS HBA ports, refer to Enabling or Disabling Multipathing on a Per-Port Basis.
The multipathing software automatically recognizes Oracle‐supported devices. If you want to enable multipathing on third-party devices, copy the /kernel/drv/scsi_vhci.conf file to /etc/driver/drv and add entries as described by Device Name Change Considerations in Multipathing Considerations.
