<div dir="ltr">Thanks again Eric!<div><br></div><div>You're wright, I have 64 pv each one 500GB hdd. I have problems with my pv starting by pv0 until pv23, I had seen after dd lvm doesn't recognize the devices of these pvs, status "unknown device", others devices I don't have the same problem.

pvXX this is One for Team or for [hdd] /dev/sdX<br>
this look like you have 64hdd for 500Gb one.<br>
<br>
and first look MBR 0-2Mb<br>
<br>
dd if=/dev/sdX of=/boot/sdX.mbr bs=512 count=4000<br>
<br>
in side sdX.mbr is <a href="http://lvm.vg" target="_blank">lvm.vg</a><br>
if is this same [ <a href="http://platinum_after_missing.vg" target="_blank">platinum_after_missing.vg</a> ]<br>
<br>
you found all record /etc/lvm/*<br>
<br>
rest is easy.<br>
<br>
device is inode, but not lv.<br>
[ -b "/dev/mapper/plt-01" ] && echo "True " || echo "False"<br>

-----<br>
segment1 == lv like /dev/sdX1<br>
<br>
pv10==[hdd X], offset[sdX1] == [ -->[xxx] ]<br>
but every one is start == 0[+offset]<br>
30730*4096=[offset]<br>
<br>
<br>
by recovery us dd if=/dev/sdX1 bs=4096 count=(1024*1000) seek=($offset)<br>

this not LVM only IBM LLVM<br>
LINUX use LVM. <a href="http://kernel.org" target="_blank">kernel.org</a><br>
IBM use AIX kernel<br>
