Juniper NETWORK AND SECURITY MANAGER 2010.4 - REV1, Installation Manual

Page: 202 / 244

NOTE: Do not start the GUI Server and the Device Server manually if the
HA Server will start them for you. The HA Server starts these processes
automatically:
• in HA configurations.
•
in non-HA configurations in which you chose during installation to have
processes restarted automatically in case of failure.
NOTE: These instructions apply only to systems where the “var” links
point to a true location outside the prescribed locations
(
/usr/netscreen/GuiSvr
or
/usr/netscreen/DevSvr
). It is not recommend
that you have these links point to locations that are inside
/usr/netscreen/GuiSvr or /usr/netscreen/DevSvr . Doing so complicates
any upgrade of NSM and requires special precautions during backup and
restore.
Configuring High Availability Options
You can manually configure the high availability options on the management system by
editing the High Availability configuration file (haSvr.cfg).
Enabling and Disabling High Availability Processes
To enable high availability:
1.
Stop the HA Server, Device Server, and then the GUI Server.
2.
Navigate to the High Availability configuration directory. For example:
cd /usr/netscreen/HaSvr/var/
3.
Open the High Availability configuration file ( haSvr.cfg ) in any text editor.
4.
To enable high availability, configure the following parameters:
highAvail.isHaEnabled=y
highAvail.isWatchdogEnabled=n
5.
Save the file.
6.
Restart the HA Server process. To do this, you must send a HUP signal to the highAvail
process. For example:
kill -HUP <process id>
Use the haStatus command to identify the highAvail process ID.
Sending a HUP signal to the highAvail process restarts the HA Server process. You do
not need to restart the server manually.
