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
(Conditional) If Sentinel was in FIPS mode before the operating system upgrade, NSS database files must be manually upgraded by running the following command:
certutil -K -d sql:/etc/opt/novell/sentinel/3rdparty/nss -X
Follow the on-screen instructions to upgrade the NSS database.
Give full permissions to novell user for the following files:
cert9.db key4.db pkcs11.txt
Upgrade your operating system.
(Conditional) If you use Mozilla Network Security Services (NSS) 3.29, two dependent RPM files libfreebl3-hmac and libsoftokn3-hmac are not installed. Manually install the following RPM files: libfreebl3-hmac and libsoftokn3-hmac.
(Conditional) For RHEL 7.x, run the following command to check whether there are any errors in the RPM database:
rpm -qa --dbpath <install_location>/rpm | grep novell
Example: # rpm -qa --dbpath /custom/rpm | grep novell
If there are any errors, run the following command to fix the errors:
rpm --rebuilddb --dbpath <install_location>/rpm
Example: # rpm --rebuilddb --dbpath /custom/rpm
Run the command mentioned in Step 7 to ensure that there are no errors.
Repeat this procedure on the following:
Collector Managers
Correlation Engines
NetFlow Collector Managers
Restart the Sentinel service:
rcsentinel restart
This step is not applicable for Sentinel HA.
