50 EMC NetWorker Release 8.1 SP1 Installation Guide
Updating from a previous release
NetWorker 8.0 and later introduces support for a new environment variable file. This file,
nsrrc, is sourced before starting the nsrexecd and nsrd processes. Subsequent NetWorker
software updates do not overwrite this new file.
Add environment variables previously defined in the NetWorker startup files to this new
file:
1. Review the configuration files you copied in “UNIX only, backing up the configuration
files” on page 42 for a list of defined environment variables.

Do not overwrite the new startup files with the contents of the .orig files. Add the old
customizations to the new environment variable file.
2. Create a Bourne shell script file called nsrrc in the /nsr directory.
3. Add the required environment variables and the export command to the nsrrc file.
For example:
ENV_VAR_NAME= value
export ENV_VAR_NAME
4. Save the file.
5. Stop the NetWorker daemons:
nsr_shutdown
6. Start the NetWorker daemons:
• On Solaris and Linux, type:
/etc/init.d/networker start
• On AIX, type:
/etc/rc.nsr
• On HP-UX, type:
/sbin/init.d/networker start
NetWorker server only, updating the Clone Storage Node attribute
When you update the NetWorker server software to NetWorker 8.1 and later, the
NetWorker software automatically creates a new Clone Storage Node attribute for each
existing Storage Node resource. The value in this attribute determines which storage node
to use when writing clone data.
In the NetWorker 7.6.x and earlier software, the Clone Storage Node attribute was present
in each NetWorker client resource. After a NetWorker server software update, the Clone
Storage Node attribute is still present in each client resource but the attribute is read-only.
The NetWorker 8.1 server does not use this attribute to determine which storage node to
use when the writing clone data for the client.
