How to check the retention of 2nd copy?

Hi,

I've changed the retention period of secondcopy for a backupid using the "bpexpdate -recalculate -backupid <bacckupid> -copy 2 -ret 9.

How can i check wether the retention changed or not?

If i use the "bpimagelist -U -backupid <backupid>" it is giving only the primary copies retention period.

Pls help
