Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

I just suspected some typo on your side.
if some device has "partitions", quoted here to denote that with evms
I assume these are virtual partions and in fact probably dm targets,
it may become difficult to claim the device itself.

if it is on purpose, just ignore that statement.
find out what evms voodo has claimed those devices already,
and deal with it.

  find /sys/block/ -path "*/holder/s*" -o -path "*/slaves/*" -ls
  dmsetup table
  dmsetup ls --tree -o inverted
or even
  head -n 2000  /proc/partitions /proc/mounts

may give some hints.
these are hints only, and not necessarily a complete list of device
dependencies. you have to use your knowledge of your system to figure
out what may be using those devices.
