Determining the Installation Type

Use any of the following methods to determine whether the HP XC system is a new installation or whether it was upgraded from a previous version:

Run the shownode command to determine the existence of the xc_prev_version parameter.
- The following example indicates that the HP XC system was upgraded from Version V2.1:
  # shownode config sysparams | grep prev xc_prev_version: V2.1
- The absence of output in following example indicates that the HP XC system is a new installation:
  # shownode config sysparams | grep prev
You can check for the existence of the /var/log/upgrade directory. If this directory exists, the HP XC system was upgraded from a previous release. Otherwise, the system is a new installation.
You can check for the existence of the /root/upgrade.log file. This file is created during a system upgrade. If this file exists, the HP XC system was upgraded from a previous release. Otherwise, the system is a new installation.
