>From the output,the tape01 has a estimated capacity of 22,030.4MB,and the 
>3570pool has a estimated capacity of 462638.5MB,what the matter?I have only 10 
>3570 tapes,why?

BTW,the the estimated capacity for sequential volumes is the total capacity of 
the pool not the capacity of the single volume,is this right?
