PART NUMBERS:
The part number for the OSF/1 v3.2 upgrade kit is
QA-MT4AA-W8 3.2 DEC OSF/1 ALPHA Upd
The part numbers for the single items are
AA-PS2BE-TE DEC OSF/1 Release Notes
AA-PS2DE-TE Guide to Installing DEC OSF/1
AA-PW8YL-TE Alpha AXP SYS SFW RL NTS OVRV
AG-PS3NL-XE DEC OSF/1 V3.2 Volume 1
AG-PTMWN-BE Alpha AXP Systems Frmwre Upd
AG-QDWBA-XE DEC OSF/1 Online
AK-Q2CRG-CA ECU Diskette V1.7 DEC Alpha
AV-PS3JN-TE DEC OSF/1 V3.2 Read This 1st
It consists of 3 CDs (OSF/1, Documentation and Firmware)
one floppy (ECU Diskette v1.7)
two manuals (release notes and installation manual)
and several individual sheets.
Each CD also has its own part number, which may be causing the confusion.
DISKTAB:
If you run OSF1/V3 or higher (not us), you do not need a disktab entry,
since the disklabel will use the DEVGETGEOM I/O control to get the geometry
reported by the drive to the driver and another I/O control to get the
partition table when you try to label the disk. You'll may then want to
edit the label to get the right rotational speed and customize the
partition table.
# diskabel -wr /dev/rrz#c whatever
If "whatever" is in the disktab file that will be used, otherwise it will
fend for itself. Newfs will use the information in the label.
SHARE SYSTEM DISKS: solution!
The DECsafe Available Server software is supported on the Model 300.
With PMAZCs or the right KZTSA, you could the two systems as
"Concurrently Active Servers".
Presumably it would splitting the file systems and having each system NFS
serve its file systems to the other. If one of the systems fails, ASE will
notice and start the recovery process to get all the file systems back onto
the remaining server.
SHARE SYSTEM DISKS: opinions:
I do not know what software the people who answered use for sharing
system disks, but the overall impression I got is that the network
slows down significantly (if you do not have fast ethernet) and the
risk is simply too high if you just have two machines (not so for
the DECsafe Available Server software?).
Most of them maintain networks of 20+ alphas and each of these have
their own operating system installed.
I really appeciate the immediate help from

here is what I have defined using the above listed entries as templates:
I am using the following partitions:
rz*a: / (
rz*b swap approx 1GB
rc*g /usr )
rc*h /usr2 (approx 3GB)
(the entries for the d e and f partition may not be consistent anymore,
so if you want to use those, you'll have to customize offset and size
yourself.)
