384 Glossary
dynamic reconfiguration Dynamic reconfiguration enables HDLM to
recognize devices whose configuration has
been changed without restarting the host
using Windows plug and play functionality.
emulation type An LU type accessible from a host. Since an
HDLM host is an open-system host such as a
PC or a UNIX machine, the HDLM host can
access only LUs with open-system emulation
types. For details on emulation types
supported by a storage system, see the
maintenance manual for that storage system.
failback Functionality for placing the status of a path
recovered from an error into Online status,
and switching the access path to the
recovered path.
failover Functionality for switching to another normal
path if there is an error in a path, thereby
enabling a system to continue to operate.
FC-SAN (fibre channel - storage area
network) A SAN using a fibre channel. Though FC-SAN
is synonymous with SAN, it is called an FC-
SAN to distinguish it from an IP-SAN.
HBA (host bus adapter) A device that functions as an interface
connecting hosts and external devices. In
this manual, the term HBA indicates an
interface card that is mounted on a host
when the host connects to a storage system
via a SCSI or FC connection.
HDLM alert driver A program that receives information about
an error detected by the HDLM driver and
then reports the error information to the
HDLM manager.
HDLM driver A program that controls the HDLM
functionality, manages paths, and detects
errors.
HDLM manager A program that manages error information.
The HDLM manager receives the error
information from the HDLM alert driver and
then collects error logs.
Host A generic name for both servers and clients.
host device A device within a host LU.
