148 EMC NetWorker Release 8.1 SP1 Installation Guide
Downgrade to a Previous Release
UNIX only, retaining start-up script customizations
The NetWorker 7.6.x software does not load the /nsr/nsrrc file before starting the
nsrexecd and nsrd daemons.
If you defined environment variables in this file, perform one of the following tasks to
retain start-up script customizations:
◆ “Restoring backup copies of the start-up script files” on page 148
◆ “Modifying the start-up script files” on page 148
Table 29 on page 148 provides a list of the NetWorker startup files for each operating
system.
Restoring backup copies of the start-up script files
Before updating the NetWorker software to version 8.1, the update process recommended
that you create a backup copy of the NetWorker start-up script files. Use these files to
replace the current start-up script files.
To restore backup copies of the start-up script files:
1. Create a backup copy of the current version of the NetWorker start-up script file.
2. Rename the NetWorker 7.6.x copy of the startup script file to the appropriate file
name.
3. Stop, then start the NetWorker daemons.
Modifying the start-up script files
If a copy of the original pre-NetWorker 8.1 start-up script files does not exist, modify the
startup script files and add the environment variables defined in /nsr/nsrrc file.
To modify the start-up script files:
1. Edit the start-up script file for the operating system.
2. Before this line: echo 'starting NetWorker daemons:' > /dev/console, add the required
environment variables, including the export command:
For example:
ENV_VAR_NAME=value
export ENV_VAR_NAME
3. Stop, then start the NetWorker daemons.
