LUN

operations
allow
hosts
that
can
use
only
a

tohaveaccess to largeramountsofdatabyusingexpandedLUs.
LUSEFunction

Open VolumeManagement.
TheLUSE function isapplied toopen-system logicalvolumesandenablesyou toconfigureone large
logical
volume
by
combining
several
small
LDEVs.
The
LUSE
function
allows
hosts
that
can
use
only
a
limitednumberof logicalunits (LUs)perfibre interface tohaveaccess to largeramountsofdataby
using expanded LUs.
Figure1onpage 11 shows the LUSE configuration. ByusingtheLUSEfunction,youcancombineseveral
logical

(LDEVs)
or

into
one
large
logical
volume.

Preparing
for
LUSE
Operations
Thischapterdescribes theenvironmentyouneed toprepare inordertooperateLUSE.
System
Requirements
TooperateLUNExpansion(LUSE),youneed the following items:
• HPstoragesystem(orsimplystoragesystemwhereapplicablehereafter)
• HPStorageWorksXPRemote WebConsolecomputer
• LicensedLUNExpansionsoftware
Note : To
use
the
LUSE
function,
you
need
the
software
called
Open
Volume
Management.
Note
that
thissoftware isonly foropensystems.
Preparing
to
Use
LUSE
Before
starting
a
LUSE
operation
on
a
selected
storage
system,
make
sure
that
you
unmount
theopen-system
volumes
and/or
remove
the
LU
paths
to
the
open
volumes.
For
instructions
on
removing
LU
paths,seeHP StorageWorksXP24000 LUN Manager User’sGuide .

ChangingLUSECapacities
There
are
two
ways
to
change
the
capacity
of
a
LUSE
volume:
• ExpandingLUSE capacities
To
expand
the
capacity
of
a
LUSE
volume,
select
the
LUSE
volume
that
you
want
to
expand,
and thenadd
LDEVsorLUSEvolumes; orfirst select LDEVs or LUSE volumes that you want
to add, and then select a LUSE volume to be expanded. For further information, see
“CreatingaLUSE Volume”onpage22.
• Reducing LUSEcapacities
You cannot reduce
the
capacity
of
an
existing
LUSE
volume.
If
you
want
a
LUSE
volume
to
have
a
smaller
capacity,
you
must
first
release
the
LUSE
volume
(see“Releasing a LUSE Volume” on page 27), and then redefine the LUSE volume (see
“Creating
a
LUSE
Volume” on page 22).
