I moved the primary path to disk to a new switch and would like to clean up the 
'disabled' path without rebooting.  Can I do this?  Is volume manager going to 
freak out because it lost its primary path?  I am using HP-UX 11.11 and VxVM 
4.1.

Example:

# sudo vxdisk list c10t1d4

Device:    c10t1d4
devicetag: c10t1d4
