When you upgrade the operating system to a major version, such as upgrading from SLES 11 to SLES 12, the upgrade procedure for the operating system deletes some Sentinel RPMs.
This version of Sentinel includes a set of commands to use during the operating system upgrade procedure. These commands ensure Sentinel works correctly after you upgrade the operating system.
NOTE:You must upgrade Sentinel before you upgrade the operating system.
Use the following steps to upgrade your operating system:
On the Sentinel server where you want to upgrade your operating system, log in as one of the following:
root user
Non-root user
Open a command prompt and change to the directory where the Sentinel install file was extracted.
Stop the Sentinel services:
rcsentinel stop
Run the following command:
./install-sentinel --preosupgrade
NOTE:If you are running this command as a non-root user, ensure that the novell user has appropriate permissions to create a file in the current working directory.
Upgrade your operating system.
(Conditional) If you are logged in as a non-root user, complete the following steps:
Switch to root user.
Run the following command:
./bin/root_install_prepare --location=<install_location> --postosupgrade
Switch to non-root user.
Run the following command:
./install-sentinel --postosupgrade
Repeat this procedure on the following:
Collector Managers
Correlation Engines
NetFlow Collector Managers
(Conditional) If you are upgrading the operating system in a traditional Sentinel installation, restart the Sentinel service:
rcsentinel restart
This step is not applicable for Sentinel HA.
