Re: specify the stripe LVM during cold installation
There is no support for striping vg00.
Sorry, you'dd better not try it.
This I thought because of the direct load of /stand/vmunix outside of LVM.

Re: specify the stripe LVM during cold installation
My thinking is I have to specify lovl1, lovl2,lvol3 in vg00 in the root disk, and these couldn't be stripe LVM. So could I join the 2th. harddisk to vg00, and specify the other LVM to be stripe LVM? Can part of LVM is stripe, and part of LVM is not stripe under the same VG?

Re: specify the stripe LVM during cold installation
You should not strippe the vg00.
The best thing to do is to use the second disk to mirror the vg00.
Create the vg00 on the first disk, then :
#pvcreate -B /dev/rdsk/cxtydz (your second disk)
#mkboot /dev/rdsk/cxtydz
#mkboot -a "hpux -lq" /dev/rdsk/cxtydz
#vgextend vg00 /dev/dsk/cxtydz
then for each lv of vg00 :
# lvextend -m 1 /dev/vg00/lvolx /dev/dsk/cxtydz

Re: specify the stripe LVM during cold installation
Striping is required only when,
a. You need better read and write performance
b. Data is not critical
Since you want to improve the performance of IUX server, I think mirror disk alone can do the trick. Because, IUX server is read intensive. Network clients boot from the IUX server and read the install image to install the OS and is not write intensive. Hence, You can plan for Mirroring the Disk. Mirrordisk UX comes built-in with HP-UX 11.11 Mission Critical OE.

Re: specify the stripe LVM during cold installation
Create vg00 and all lv on first disk.
# lvcreate lv_depot vg00
# lvextend -L
# newfs -F vxfs /dev/vg00/rlv_depot
Now the lv_depot is on the second disk.

Re: specify the stripe LVM during cold installation
My understanding is since the IUX server is read intensive, so stripping should be able to have better performance. Why have to be both read and write intensive?
if my understanding is wrong, please correct me?
