Setting
the
queue
depth
for
the
HP-UX
operating
system
with
fibre-channel
adapters
Before
you
set
the
queue
depth,
you
must
connect
the
host
system
to
the
storage
unit.
See
“General
information
about
attaching
to
open-systems
host
with
fibre-channel
adapters”
on
page
12.
1.
Use
the
following
formula
to
set
the
queue
depth
for
all
classes
of
HP-UX:
256
÷
maximum
number
of
LUNs
=
queue
depth
Note:
Although
this
algorithm
implies
that
the
upper
limit
for
the
number
of
LUNs
on
an
adapter
is
256,
HP-UX
supports
up
to
1024
LUNs.
2.
You
must
monitor
configurations
with
greater
than
256
LUNs.
You
must
adjust
the
queue
depth
for
optimum
performance.
3.
To
update
the
queue
depth
by
device
level,
use
the
following
command:
scsictl
-m
queue_depth=21
/dev/rdsk/$dsksf
where
/dev/rdsk/$dsksf
is
the
device
node.
4.
To
make
a
global
change
to
the
queue
depth,
use
the
HP
System
Administration
Manager
(SAM)
to
edit
the
kernel
parameter
so
that
it
equals
scsi_max_qdepth.
Configuring
the
storage
unit
for
clustering
on
the
HP-UX
11iv2
operating
system
This
section
describes
how
to
configure
a
storage
unit
for
clustering
on
the
HP-UX
11iv2
operating
systems
that
use
the
MC/ServiceGuard
11.14.
