disabled dmp paths should be able to be removed from the OS even the diskgroup is deported
for linux as well, if you force removed the paths with echo 1 > /sys/block/$disk/device/delete
there would be a bunch of NONAME devices in vxdmpadm getsubpaths
because dmp is holding on to the device path somehow even though it is disabled.
basically, IMHO, in mission critical systems, it should be a reasonable thing to remove a disabled path without requiring the diskgroup being deported.
