I have already send mail about it, but ...
This looks like a long reset time for the disk. The Ultrix SCSI driver resets 
the bus and than begins polling all addresses with the INQUIRY. If a device 
has not recovered form the reset yet, it won't be recognized and configured.
I saw a lot of this with the optical devices and jukeboxes. 
Solution : insert a small (~3-5sec) delay after reset in the probe routine.
