If multiple paths exist between your host bus adapters (HBAs) and the storage devices, configure multipathing for the devices before creating software RAIDs or file system volumes on the devices. For information, see Chapter 5, Managing Multipath I/O for Devices.
If you want to configure software RAIDs, do it before you create file systems on the devices. For information, see Chapter 6, Managing Software RAIDs with EVMS.
