kept seeing this during chef run

================================================================================
Error executing action `run` on resource 'ruby_block[create_logical_volume_apps_vg_websphere_lv]'

TypeError
---------
String can't be coerced into Fixnum

i looked at some earlier versions of lvsseg.yaml and Integer was specified
where i saw String in lvsseg.yaml, so i changed this file to specify Integer
rather than string for several items.

local testing has been successful
