I have an AT&T 6386/25 WGS running with 2 Seagate 90MB SCSI disks.  I am using
the disk mirroring facilities to mirror drive 0 onto drive 1 exactly. 
Apparently, the SCSI disk mirroring utilities written by AT&T generate "shadow"
processes to complete their work.  This situation is quite noticeable, and
the ps command gives confusing results.  Does anybody have any
information on this implementation, why it was done, what to watch out for?
Thanks in advance.
