Disaster Recovery

[Stephen Young_1]

Hi,

I am in the process of planning a disaster recovery of a V-Class onto an N-Class.
I have been informed that I will not be able to use ignite as I am going from V to N so I will have to do a clean install.
Can anyone suggest key files that I will need to make a copy of ?

Cheers

Steve

Hi Stephen:

Here's the basic list I tranfer to safe-keeping for reference, reuse, and comparing against new configurations (via 'diff') during a cold installation process:

# /.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/

Don't forget to add your volume group 'vgexport' mapfiles too.

Regards!

Key files for DR:
/etc/passwd
/tcb/* if the system is trusted
/etc/group
/etc/hosts
/etc/nsswitch.conf
/etc/resolv.conf
Any custom startup scripts, for starting Oracle for example
/var/spool/cron/crontabs/*
/etc/services
/etc/inetd.conf
all . files for root

The absolute key files are /etc/passwd (with /tcb if trusted) and /etc/group if there are a lot of users that log onto the system directly.
