Wrong URL for CD2 with installations over nfs

Hi I tried to use autoyast for SLES9 over nfs. After I pass SLES CD1, CORE CD1 and reach CORE CD2 I get an error "Insert Media SUSE CORE Version 9 CD 2 ERROR(Media: not attached)". The given URL for the media is nfs://10.128.1.20/local/software/suse/SLES9//core-i386/CD2 The same error for cd 3,4,5 Where does this double-slash between SLES9 and core-i386 come from? Thanks, Stefan Mayr
