H HBA (Host Bus Adapter) Device that functions as an interface connecting a host with external devices. In this manual, the term HBA refers to an interface card installed in a host, in configurations where the host and storage units are connected via a FC connection. HDLM driver A program that controls all the HDLM functions, manages paths, and detects errors. host An ESXi server that connects to storage subsystems via a SAN. host device A logical area in a host LU. (See also: host LU, host device name) host device name A name assigned to a host device. host LU An LU that a host recognizes. The actual HDev entity is a Dev in the storage system. Each host LU has a host LU number. (See also: LU, host LU number, host device) host LU number A number assigned to a host LU. The host LU number is part of a path name. (See also: host LU, path name) I intermittent error An error that occurs irregularly due to, for example, a loose cable connection. L LDEV (Logical Device) A combination of the storage system's product name, serial number, and an internal LU. HDLM uses this value to identify a particular LU. load balancing Functionality for distributing the load across the paths that access each area within an LU. To distribute loads, load balancing uses multiple paths to perform I/O operations. # ABCD E F GH I J K LMNOPQR S T U VWX Y Z Hitachi Dynamic Link Manager User Guide (for VMware(R)) Glossary-3
