1. /usr/sbin/lvcreate -C y -L 14000 -n lvdump -r n -s y /dev/vg03
2. /usr/sbin/lvlnboot -d /dev/vg03/lvdump
But after executing #2 it returned a no valid boot data message.
# /usr/sbin/lvlnboot -d /dev/vg03/lvdump
No valid Boot Data Reserved Areas exist on any of the
Physical Volumes in the Volume Group "/dev/vg03".
Issue the pvcreajavascript:postMessageSubmit('submit');te -B command to create a Boot Area on a Physical Volume.
I read the man pages for lvlnboot and I made use of all the right options for creating a dump lv. What seems to be the problem and why I can't execute lvlnboot?
TIA
Solved! Go to Solution.

Re: Failure in Creating Dump lvol
# /usr/sbin/lvdisplay -v /dev/vg03/lvdump
--- Logical volumes ---
LV Name /dev/vg03/lvdump
VG Name /dev/vg03
LV Permission read/write

as you can see its allocation is strict/contiguous and bad block is off which are the requirements of a dump device.

Re: Failure in Creating Dump lvol
The dump area is at least 50% of system ram?
Please try this:
/usr/sbin/lvlnboot -d /dev/vg03/lvdump
rc=$?
echo "response code is : $rc"
I'd like to see what the system response is.
as an additional guide:
Creating a compressed system dump (11.23)
http://www.docs.hp.com/en/5992-2852/ch05s02.html
http://docs.hp.com/en/5434/Cdump_WP.book.pdf
I don't know which docs to give you because I don't know your OS.
Hopefully a generic document:

Re: Failure in Creating Dump lvol
So when you are creating a disk that is going to be use to boot the system you should create it with the -B option.
#pvcreate -B /dev/disk
but why don't u use the boot swap space device that is in vg00 for dump ?
if you need more dump space, you don't have to add it at boot time, just add it to /etc/fstab:
/dev/vg03/lvdump ... crash default 0 0
and to add it before the reboot:
#crashconf /dev/vg03/lvdump

This guide includes a complete procedure to mirror, which replicated the dump area on a second disk, making it bootable.
It therefore contains all the information you need to do a dump area (and a lot more).
