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

lvextend
LVEXTEND(8) System Manager's Manual LVEXTEND(8)
NAME
lvextend - extend the size of a logical volume
SYNOPSIS
lvextend [--alloc AllocationPolicy] [-A|--autobackup y|n] [-d|--debug] [-h|-?|--help] [--noudevsync] [-i|--stripes Stripes [-I|--stripesize
StripeSize]] {-l|--extents [+]LogicalExtentsNumber[%{VG|LV|PVS|FREE|ORIGIN}] | -L|--size [+]LogicalVolumeSize[bBsSkKmMgGtTpPeE]}
[-t|--test] [-v|--verbose] LogicalVolumePath [PhysicalVolumePath[:PE[-PE]]...]
DESCRIPTION
lvextend allows you to extend the size of a logical volume. Extension of snapshot logical volumes (see lvcreate(8) for information to cre-
ate snapshots) is supported as well. But to change the number of copies in a mirrored logical volume use lvconvert(8).
OPTIONS
See lvm for common options.
--noudevsync
Disable udev synchronisation. The process will not wait for notification from udev. It will continue irrespective of any possible
udev processing in the background. You should only use this if udev is not running or has rules that ignore the devices LVM2 cre-
ates.
-l, --extents [+]LogicalExtentsNumber[%{VG|LV|PVS|FREE|ORIGIN}]
Extend or set the logical volume size in units of logical extents. With the + sign the value is added to the actual size of the
logical volume and without it, the value is taken as an absolute one. The number can also be expressed as a percentage of the total
space in the Volume Group with the suffix %VG, relative to the existing size of the Logical Volume with the suffix %LV, of the
remaining free space for the specified PhysicalVolume(s) with the suffix %PVS, as a percentage of the remaining free space in the
Volume Group with the suffix %FREE, or (for a snapshot) as a percentage of the total space in the Origin Logical Volume with the
suffix %ORIGIN.
-L, --size [+]LogicalVolumeSize[bBsSkKmMgGtTpPeE]
Extend or set the logical volume size in units of megabytes. A size suffix of M for megabytes, G for gigabytes, T for terabytes, P
for petabytes or E for exabytes is optional. With the + sign the value is added to the actual size of the logical volume and with-
out it, the value is taken as an absolute one.
-i, --stripes Stripes
Gives the number of stripes for the extension. Not applicable to LVs using the original metadata LVM format, which must use a sin-
gle value throughout.
-I, --stripesize StripeSize
Gives the number of kilobytes for the granularity of the stripes. Not applicable to LVs using the original metadata LVM format,
which must use a single value throughout.
StripeSize must be 2^n (n = 2 to 9)
Examples
"lvextend -L +54 /dev/vg01/lvol10 /dev/sdk3" tries to extend the size of that logical volume by 54MB on physical volume /dev/sdk3. This is
only possible if /dev/sdk3 is a member of volume group vg01 and there are enough free physical extents in it.
"lvextend /dev/vg01/lvol01 /dev/sdk3" tries to extend the size of that logical volume by the amount of free space on physical volume
/dev/sdk3. This is equivalent to specifying "-l +100%PVS" on the command line.
"lvextend -L+16M vg01/lvol01 /dev/sda:8-9 /dev/sdb:8-9"
tries to extend a logical volume "vg01/lvol01" by 16MB using physical extents /dev/sda:8-9 and /dev/sdb:8-9 for allocation of extents.
