Powerpath question

hi

Does any one know how to free up emcpower devices, let me explain

I have a solaris server with 50 powerpath devices  from 0 to 49, i unmasked some devices (five devices) those devices in powerpath became to dead, i ran the powermt check and clean powerpath, but if i take a look at inq list i have the output as follows

emcpower0

emcpower1

emcpower7

..

..

..

emcpower49

if you see from emcpower2 to emcpower6 there is a gap and if i mask new devices and reconfigure powerpath those new powerpath devices start at emcpower50 emcpower51 and so on,

if i use this command to get the used powerpath devices emcpadm getusedpseudos i see that those device are still used but those devices dont exist anymore on the server

how can i do to get free those emcpowers and when i mask new devices use those emcpower (emcpower2, emcpower3, emcpower4 , emcpower5 and emcpower6

Best regards
