RAID 0 on Unix

I was wanting to know if anyone knew how to setup RAID 0 on an old HP Unix server. It's for where I work and my boss has two hard drives and wants the second to take over if the first one fails hence RAID 0. If anyone could help me it would be greatly appreciated.

Check the man page of lvcreate. This has the -m option which will allow you to create mirror copies. However, this will require MirrorDisk/UX software to be installed on your HP box.

You could contact your HP support to get MirrorDisk if you already do not have it.

I just build a raid0 this week w/the following...
manny

#!/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

Um,
raid 0 is striping (no redundancy)
raid 1 is mirroring

you definitely do NOT want to raid0 anything you care about...
manny

raid1 example below:
#!/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
