Thanks to all who helped solve the format problem we were having.  Here is
the summary for anyone who faces the same problem.


The original posting:

---- Begin Included Message ----

Hardware: Sun 4/380 with
            a Seagate ST42400N SCSI disk drive (2.5 GB unformatted) and
            a Fujitsu M2263SA SCSI disk drive (boot disk, terminated)
OS Level: SunOS 4.1.2

Our problem:

We are encountering problems while trying to install the ST42400N drive.
The ST42400N drive formats w/o errors, but consistently fails and aborts
during the first surface analysis pass at cylinder 1330 with the following
error message:

Assertion failed: file "ctrl_scsi.c", line 2331

Additional information:

This drive was originally formatted on the 4/380 under SunOS 4.1.1. The format
and surface analysis completed without any problems and we were able to create 
filesystems on the drive.

We have two of these Seagate ST42400N drives and encounter the same error on
both drives.

Moving either of these drives to an SS2 at SunOS 4.1.2 enables us to complete
the formatting and two surface analysis passes without errors.

We are using the following format.dat entry obtained from sun-managers:

disk_type = "Seagate ST42400N" \
        : ctrl = SCSI : fmt_time = 4\
        : trks_zone = 19 : asect = 6 : atrks = 19 \
        : ncyl = 2622 : acyl = 2 : pcyl = 2624 : nhead = 19 : nsect = 83 \
        : rpm = 5400 : bpt = 55440

partition = "Seagate ST42400N" \
        : disk = "Seagate ST42400N" : ctrl = SCSI \
        : a = 0, 39425 : b = 25, 197125 : c = 0, 4134894 : g = 150, 3898344

 
Has anyone else seen this problem? Are we missing a patch for the sun4 arch?
Any help would be appreciated.

I received (at this point) nine replies to this posting.  Here are the results:
(the number in parens is the number of people with that reply)

1. Same problem on a Sun 4/490.  Format the drive on the SS2 and move it to
   the Sun 4/380. (1)

2. Same problem - SunOS 4.1.2 needs a patch.  The patch number is 100474-01
   the bug ID is 1074337.  See number 4 for more details. (6)

3. Same problem on a Sun 4/280 using a VME SCSI controller.  The interface
   card would drop high-end bits, folding addresses beyond 1.0 GB to lower
   addresses.  Solution, format on a IPC. (1)

4. This reply came from a drive vendor.  This is a well known problem.  It 
   is caused by a problem in reading the defect list that eventually 
   causes label problems.  The bug ID was 1074377 and the Sun patch that
   corrects it is 100474-01.  This is described in the Sun 4.1.2 release
   documentation. (1) 

I applied patch 100474-01 and reformatted the drive last night.  Everything
worked fine.  Thank you to all who replied:
