<<I'd like to exchange all our disks in 918RX (MPE 5.0). Now we have
internaly 2*2GB (A3087A)as one system volume set, and we want to have
2*4GB (A3352A)instead. No other disks are connected. (Disks supposed to
be taken off, will be used with other HP3k system).

I hope no miracle is needed to do it, and if someone has experience and
can provide me with some hints, I'd be grateful.>>


It's fairly straightforward:

1) Run :SYSGEN and update the ID= values of the disks to the new values
2) Run BULDACCT.PUB.SYS with the '@' parameter. If you're not familiar
with BULDACCT, just run it interactively and use the '%HELP' command to
have it tell you about itself
3) Turn off UDCs for MANAGER.SYS that might cause problems on a restart
4) Make an SLT
5) Make another SLT
6) Verify at least one of the SLTs with CHECKSLT.MPEXL.TELESUP
7) Make a full system backup; i.e. :STORE /;*T;DIRECTORY (or @[log in to unmask]@ if you
prefer)
8) Make another full system backup
9) :VSTORE one or both of the backups

Note that you can combine the SLT with the full system backup if you use
the STORE= option of the :SYSGEN 'TAPE' command with an indirect file
containing a line like
 /;DIRECTORY[;SHOW;PROGRESS;whatever other options you like]

10) Shut down the system
11) Swap the drives. Make sure that the SCSI IDs of the new drives are
set to match those of the drives they are replacing.
12) Start the system
13) ISL>INSTALL from the SLT
14) :RESTORE BULDJOB1.PUB.SYS
15) :STREAM BULDJOB1 to regenerate your account structure and users
16) :RESTORE / (or @[log in to unmask]@);OLDDATE to get all your files back
17) :STREAM BULDJOB2 to re-attach your UDCs

If you have the "Installation, Update, and Add-on Manual" from your 5.0
installation or the "PowerPatch Installation Manual" from one of your
PowerPatch packages, it will step you through the process, albeit in a
much more verbose format. Use the "Reinstall" path, inserting the
hardware swap between the save-everything and the put-it-back phases.
