Thanks again Eric!
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. I cut this output from dd of hdisk plt-85 = pv64
Device with problem
-----
pv0 {
id = "N7lOu9-Ahjn-lf19-WVFW-xglN-yfL6-KOOw6O"
device = "unknown device"
status = ["ALLOCATABLE"]
flags = ["MISSING"]
dev_size = 1048576000
pe_start = 2048
pe_count = 127999
}
-----
Device without problem
-----
pv24 {
id = "D8aEQf-2CVS-oyVE-t40G-kOd7-eUe5-SkCe8V"
device = "/dev/mapper/mpathr"
status = ["ALLOCATABLE"]
flags = []
dev_size = 1048576000
pe_start = 2048
pe_count = 127999
}

But the output from another hdisk plt-01 = pv0 I have different view.
-----
pv0 {
id = "N7lOu9-Ahjn-lf19-WVFW-xglN-yfL6-KOOw6O"
device = "/dev/mapper/plt-01"
status = ["ALLOCATABLE"]
flags = ["MISSING"]
dev_size = 1048576000
pe_start = 2048
pe_count = 127999
}

I'm getting crazy lol...
Thank you

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

}
-----
segment1 == lv like /dev/sdX1
pv10==[hdd X], offset[sdX1] == [ -->[xxx] ]
but every one is start == 0[+offset]
30730*4096=[offset]
by recovery us dd if=/dev/sdX1 bs=4096 count=(1024*1000) seek=($offset)
this not LVM only IBM LLVM
LINUX use LVM. kernel.org
IBM use AIX kernel
