You need to specify all images on the restore command (first step - restore... redirect). Here is an example:
bkogan@panipuri /home/bkogan > db2 create db test automatic storage no
DB20000I The CREATE DATABASE command completed successfully.
bkogan@panipuri /home/bkogan > mkdir BK1 BK2 BK3
bkogan@panipuri /home/bkogan > db2 "backup db test to /home/bkogan/BK1, /home/bkogan/BK2, /home/bkogan/BK3 compress"
Backup successful. The timestamp for this backup image is : 20091219140910
bkogan@panipuri /home/bkogan > ls -l BK*
BK1:

bkogan@panipuri /home/bkogan > db2 "restore db test from /home/bkogan/BK1, /home/bkogan/BK2, /home/bkogan/BK3 into test2 redirect"
