[esamorokov]

BlackCat,
     I think this table should make it a little bit clear, i hope :)


	*State #1* 	*State #2* 	*State #3* 	*State #4*
*ada1 (ada1p2)* 	OK 	OK 	DISCONNECTED 	CONNECTED (OLD POOL)
*ada2 (ada2p2)* 	OK 	OK 	OK 	OK (new Pool)
*ada3 (ada3p2)* 	OK 	FAILED 	REPLACED 	CONNECTED FAILED DRIVE (OLD POOL)
*ZH_VOL (pool)* 	OK 	DEGRADED 	DESTROYED 	RECREATED


Thank you,
Evgeny.
