target host when an LU is deleted or all
paths connected to the LU are placed in
Offline(E) status.
reservation The reservation functionality enables a host
to declare that it has exclusive use of an LU,
thus preventing other hosts from accessing
that LU. Access permission for a reserved LU
is given only to the host that issued the
reservation, so the LU cannot be accessed
from multiple paths simultaneously. As a
result, load balancing is not possible.
SAN (storage area network) A high-speed network connecting hosts and
storage systems. This network is independent
of a LAN and is dedicated to data transfer. A
SAN provides faster accesses to storage
systems, and prevents the transfer of high-
volumes of data from deteriorating LAN
performance.
SLPR(storage logical partition) A function, supported by the TagmaStore
USP, and Universal Storage Platform V, for
logically splitting a storage system. This
function splits the resources (ports, CLPR,
and volumes) in the storage system, so that
the user can manage each resource
independently.
