Informix Online - Table disk location

I am running Informix Online 4.1 on a hp 9000 running hp-ux 8.02 I have set up the database so tables are spread across three different disks on raw disk partions. My question is, is there an easy way to find out where a particular table is located on disk. I have used tbstat -t, and looked at the address of the particular table, but tbstat only shows the active tables. I have looked in the systables table, and the partnum is similar to the address. How does the address or partnum related to the location of the table in a particular dbspace or disk partion? -lad@remus.rutgers.edu
