ioscan -En how to exclude tapes?

i would like to list all disks, but this command with these options list tapes too.

i don�t find out an option which list only the class like ioscan in hp-ux.

could anybody help me?

thanks a lot.

parse the output through "sed" or "grep" if there is no other way...

thanks for your help, i�ll use vi to edit the output file.
