Gathering CUOS Installation Information Prior to Upgrade

It may sound obvious, but prior to any upgrade – prepare for the eventuality of a system rebuild.  I hit an upgrade today that required both a Recovery CD partition swap and file system check on the original Active Partition to recover the system, after SELinux failures occurred after a switch-version.

For a rebuild, collect the following from CLI prior to upgrade:

  1. show network eth0 

  2. show status

  3. show version active

  4. utils ntp config

  5. show web-security

 

This will collect IP/Hostname, DNS, NTP/Timezone, firmware and certificate details(last one is critical!).

This is all negated if you have Answer Files set up to begin with and/or are using PCD.
