Adding an ST410800N SCSI drive

We have a new Alpha 2000, Model 300 with OSF/1 v3.0.

I am new to managing a UNIX system and to the DEC Alpha; I suspect my problem
may well have a simple solution.

The problem is trying to install a 9 GB Seagate ST410800N SCSI hard drive.

I've tried to infer the appropriate steps from the man pages, this group's
archives, and the System Administration documentation, but the system always
seems to hang while running newfs.

Here's basically what I've tried:

- checked the existing SCSI IDs (0 - an internal 1 GB drive and 4 - a CD-ROM)
- assigned the ST410800 to an open ID (6)
- cp /vmunix /usr/vmunix.save
- /usr/sbin/shutdown -r now
- log on as root, shutdown to single user mode
- mount /usr
- run /usr/sbin/doconfig for <system name>
- /mv /sys/<system name>/vmunix /vmunix
- /usr/sbin/shutdown -r now
- disklabel -w -r /dev/rz6 ST41080 "MARSHALL Ext 1"
- disklabel -r /dev/rrz6a (which produces a long report:)
(disklabel report - reproduced from my notes)
type: SCSI
disk: RZxx
label: MARSHALL Ext 1
flags: dynamic_geometry
bytes/sector: 512
sectors/track: 133
tracks/cyl.: 27
sectors/cyl.: 3591
cyl.: 4926
sectors/unit: 17755614
rpm: 3600
interleave: 1
trackskew: 0
lskew(?): 0
headswitch: 0
track_to_track seek: 0
drivedata:0
8 partitions
# size offset fstype [fsize bsize cpg]
a: 131072 0 unused 0 0 # cyl.: 0-36*
b: 262144 131072 unused 0 0 # cyl.: 36*-109*
c: 17755614 0 unused 0 0 # cyl.: 0-4944*
d: 0 0 unused 0 0 # cyl.: 0--1
e: 0 0 unused 0 0 # cyl.: 0--1
f: 0 0 unused 0 0 # cyl.: 0--1
g: 17362398 393216 unused 0 0 # cyl.: 109*-4944*
h: 0 0 unused 0 0 # cyl.: 0--1

- /usr/sbin/newfs /dev/rrz6a
 works fine: 1795 sectors in last cyl.(?) unallocated
             67.1 MB in size
             super-block backups at 32, 57632, 115232

- /usr/sbin/newfs /dev/rrz6b
 works fine: 3590 sectors in last cyl.(?) unallocated
             134.2 MB in size
             super-block backups at 32, 57632, 115232, 172832, 230432

- when I try the same thing with the g partition, the system invariably seems
  to crash
        - several times it has only reported out 5-10 lines of super-block
          backup locations
        - once it got all the way through (running newfs -N reports all the
          locations without running the command)
        - then it (the machine?) just stops

- in my ignorance, I also tried AdvFS (ie, mkfdmn and then mkfset) but again
  the machine seems to just stop when running mkfset

Any suggestions?

Thanks very much for any help you can offer.
