Dear SCO Customer,

Support Level Supplement (SLS) ptf7611b, the UnixWare 7.1.1 pdimkdev 
Supplement, addresses the following problem:

ptf7611a addresses the following problems:
    sdighost -r [see sdighost(1M)] does not permanently remove the names of
    disks in the sdi database that do not correspond to any physical disks
    on the system ('phantom' disks). 

   With SLS ptf7611a, sdighost -r removes unwanted "vtoc" entries from the 
   resmgr database and updates the configuration regardless of whether there 
   are any ghost disks or not.

ptf7611b only adds the option to do a quiet install.

SLS ptf7611 contains:

        /etc/scsi/pdimkdev
