RAID 5 on HP-UX

Hi, i had search through this forum about the RAID 5 configurations on HPUX server (model RP5470) but only find this thread:
RAID 0 on Unix

.. there are two way to configure the RAID that provided from this thread

RAID 0
****************
#!/bin/sh
pvcreate -f /dev/rdsk/c4t1d0
pvcreate -f /dev/rdsk/c1t1d0

mkdir /dev/vg01
mknod /dev/vg01/group c 64 0x0a0000

vgcreate -p 128 /dev/vg01 /dev/dsk/c4t1d0

vgextend /dev/vg01 /dev/dsk/c1t1d0
# -i represents number of drives you are stripping across
lvcreate -i 2 -I 128 -n lvol1 -r N /dev/vg01

lvextend -l 2046 /dev/vg01/lvol1 /dev/dsk/c4t1d0 /dev/dsk/c1t1d0

newfs -F vxfs /dev/vg01/rlvol1
fsadm -F vxfs -o largefiles /dev/vg01/rlvol1

mkdir /raid0filesystem

mount /dev/vg01/lvol1 /raid0filesystem

exit

RAID 1
****************
#!/bin/sh
pvcreate -f /dev/rdsk/c4t1d0
pvcreate -f /dev/rdsk/c1t1d0

mkdir /dev/vg01
mknod /dev/vg01/group c 64 0x0a0000

vgcreate -p 128 /dev/vg01 /dev/dsk/c4t1d0

lvcreate -n lvol1 /dev/vg01
#extents number will vary
lvextend -l 1023 /dev/vg01/lvol1

newfs -F vxfs /dev/vg01/rlvol1
fsadm -F vxfs -o largefiles /dev/vg01/rlvol1

mkdir /raid1filesystem

mount /dev/vg01/lvol1 /raid1filesystem

vgextend /dev/vg01 /dev/dsk/c1t1d0
#this part may take a while...the more you mirror the longer it takes
lvextend -m 1 /dev/vg01/lvol1

exit

************************

for your information, my HP-UX server (model RP5470) had its RAID card attached to it, so, the server should can configure RAID 5 without any problem. Right now, i had manage to modify the configuration so that it would be run as RAID 5... but i dont know whether it can be act like i want to run or not, or how i want to make sure that it run as RAID 5 or not..

here is my pre-configure RAID 5

RAID 5
****************

#!/bin/sh
#minimum disk for RAID 5 required = 3
pvcreate -f /dev/rdsk/c4t1d0 <--disk1
pvcreate -f /dev/rdsk/c1t1d0 <--disk2
pvcreate -f /dev/rdsk/c2t1d0 <--disk3

mkdir /dev/vg01
mknod /dev/vg01/group c 64 0x0a0000

vgcreate -p 128 /dev/vg01 /dev/dsk/c4t1d0

lvcreate -n lvol1 /dev/vg01
#extents number will vary
lvextend -l 1023 /dev/vg01/lvol1

newfs -F vxfs /dev/vg01/rlvol1
fsadm -F vxfs -o largefiles /dev/vg01/rlvol1

mkdir /raid1filesystem

mount /dev/vg01/lvol1 /raid5fs

vgextend /dev/vg01 /dev/dsk/c1t1d0

lvextend -m 1 /dev/vg01/lvol1

exit

mount /dev/vg01/lvol1 /raid5fs

exit
*************************

hope someone could help me on this.

NAME

     iir -- Intel Integrated RAID controller and ICP Vortex driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel configuration file:

           device pci
           device scbus
           device iir

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

           iir_load="YES"

DESCRIPTION

     The iir driver claims to interface with the Intel integrated RAID controller cards, and all versions of the ICP Vortex controllers (including
     FC).

HARDWARE

     Controllers supported by the iir driver include:

     o   Intel RAID Controller SRCMR
     o   Intel Server RAID Controller U3-l (SRCU31a)
     o   Intel Server RAID Controller U3-1L (SRCU31La)
     o   Intel Server RAID Controller U3-2 (SRCU32)
     o   All past and future releases of Intel and ICP RAID Controllers.

     o   Intel RAID Controller SRCU21 (discontinued)
     o   Intel RAID Controller SRCU31 (older revision, not compatible)
     o   Intel RAID Controller SRCU31L (older revision, not compatible)

     The SRCU31 and SRCU31L can be updated via a firmware update available from Intel.
