We recently installed SP4 on an ADSM system that had been operational with
SP3.  The Qualstar robot initially didn't show up in the SCSI devices,
although the drives did.  We then got the robot back, but adsmscsi.sys
didn't recognize it as an ADSM robot.  After a number of trials, we found a
new version of a driver for the Adaptec 2944 on the Adaptec web site.  The
robot came up immediately.

Just wanted to pass this on before someone else has the problem.
