path

The directory location of a given file or directory on a file system. Paths can be either relative or absolute.

The route through which a host accesses data on a storage medium such as a disk in an array. The path consists of an HBA (host bus adapter) on the host, a SCSI or Fibre Channel connector, and a controller on the disk or disk array.

When a disk is connected to a host, the path to the disk consists of the HBA (Host Bus Adapter) on the host, the SCSI or fibre cable connector and the controller on the disk or disk array. These components constitute a path to a disk. A failure on any of these results in DMP trying to shift all I/O for that disk onto the remaining (alternate) paths.
