What are those  /dev/mapper/plt-XX  devices ?

It seems like the lvm2 command cannot write to this place properly?

Checksum error looks like serious problem.

 From attached output - all your PVs were properly markes as not missing,
however the lvm2 cannot read back proper crc code.

So what are those 0.5GB devices - are they properly writable ?
(especially in the disk header)

Note - there are special type of block devices like DASD devices
that must be first properly configured by IBM storage manager to provide 
regular devices.

Regards

Zdenek
