Installing unix 11.00

[Jeff Hagstrom]

I have a box that is running 10.20. I need to wipe the box clean and install 11.00. There is nothing on that box that is needed. The box has gone thru some attempts at upgrading to 11.00, but there has been a rash of system panics that have prevented us from completing. Now, I'd like to reformat all the drives and load 11.00 from the cdrom, setup my file systems and then load my applications. Is there a process to wipe out the system that exists and then re-install unix 11.00?

The way to do that is just to boot from the CD, select which drive you want to install the OS to and let it fly. You will get a warning that there is already an OS present on the disk, if you continue it will be wiped out, or something to that effect. You just acknowledge that warning and it will start with a new installation on that disk.

I normally just let the install process do everything to the vg00 (root disks). As part of the install it will say that there is a bootable OS on the disk but you can confirm that you want to overwrite this. Once the OS has been installed , pvcreate -f on any other disks to remove the vg information. To me this is just as good as any formatting.

Jeff,

There's no need to wipe out the old OS. You just boot from the install CD and install HP-UX. IF you choose the right disks for the OS there's no many resons for system crash. For sure not the old OS ...

Hi Jeff:

If you want to start from scratch simply cold-install (boot from) the Core OS Install/Update/Recovery CDROM. Select your 64-bit CDE environment and the disk you want for vg00 and size your logical volumes and primary swap space.

Take time to size your logical volumes according to your enviornment. The default values are generally far too conservative.

Load the Core OS followed by the Applications, CDROM(s); Diagnostics (STM, EMS and Predicitve Support) and then the current General Release (GR) patches.

Before destroying your current configuration you might want to capture (to tape or to a disk which you will later 'vgimport') key configuration files which you will need to reestablish and/or reference to build new ones. This list should include:

# /.forward
# /.profile
# /etc/profile
# /etc/group
# /etc/hosts
# /etc/inetd.conf
# /etc/inittab
# /etc/nsswitch
# /etc/ntp.conf
# /etc/passwd
# /etc/rc.config.d/netconf
# /etc/rc.config.d/netdaemons
# /etc/rc.config.d/nfsconf
# /etc/resolv.conf
# /etc/sendmail.cf
# /etc/services
# /etc/shells
# /etc/shutdown.allow
# /var/adm/cron/*.allow
# /var/adm/fbackupfiles/*
# /var/spool/cron/crontabs/*
# /sbin/init.d/
