After you install Sentinel, you need to perform additional configuration for the appliance to work properly.
You must register the Sentinel appliance with the appliance update channel to receive Sentinel and latest operating system updates. To register the appliance, you must first obtain your appliance registration code or the appliance activation key from the Customer Care Center.
Based on the operating system you install, you can register for updates in the following ways:
If you are using SLES 12 SP3 or later, you can register using the Sentinel appliance management console.
If you are using SLES 12 SP3 or later, you can register using commands.
To register using the Sentinel appliance management console:
Launch Sentinel appliance by doing either of the following:
Log in to Sentinel. Click Sentinel Main > Appliance.
Specify the following URL in your web browser: https://<IP_address>:9443.
Log in as either vaadmin or root user.
Click Online Update > Register Now.
In the Email field, specify the email ID to which you want to receive updates.
In the Activation Key field, enter the registration code.
Click Register to complete the registration.
To register using commands:
Log in to the Sentinel server as the root user.
Specify the following commands:
To register server, specify: suse_register -a regcode-sentinel="<registration_code>" -a email="<email_ID>"
To register Collector Manager, specify: suse_register -a regcode-sentinel-collector="<registration_code>" -a email="<email_ID>"
To register Correlation Engine, specify: suse_register -a regcode-sentinel-correlation ="<registration_code>" -a email="<email_ID>"
To register Sentinel in high availability, specify: suse_register -a regcode-sentinel-ha ="<registration_code>" -a email="<email_ID>"
For the email parameter, specify the email ID to which you want to receive updates.
The information in this section is applicable only if you want to use traditional storage as the data storage option.
As a best practice, ensure that you create separate partitions to store Sentinel data on a different partition than the executables, configuration, and operating system files. The benefits of storing variable data separately include easier backup of sets of files, simpler recovery in case of corruption, and provides additional robustness if a disk partition fills up. For information about planning your partitions, see Planning for Traditional Storage. You can add partitions in the appliance and move a directory to the new partition by using the YaST tool.
Use the following procedure to create a new partition and move the data files from its directory to the newly created partition:
Log in to Sentinel as root.
Run the following command to stop the Sentinel on the appliance:
/etc/init.d/sentinel stop
Specify the following command to change to novell user:
su - novell
Move the contents of the directory at /var/opt/novell/sentinel to a temporary location.
Change to root user.
Enter the following command to access the YaST2 Control Center:
yast
Select System > Partitioner.
Read the warning and select Yes to add the new unused partition.
For information about creating partitions, see Using the YaST Partitioner in the SLES 11 documentation.
Mount the new partition at /var/opt/novell/sentinel.
Specify the following command to change to novell user:
su - novell
Move the contents of the data directory from the temporary location (where it was saved in Step 4) back to /var/opt/novell/sentinel in the new partition.
Run the following command to restart the Sentinel appliance:
/etc/init.d/sentinel start
In secured environments where the appliance must run without direct Internet access, you can configure the appliance with the Subscription Management Tool (SMT), which enables you to upgrade the appliance to the latest versions of Sentinel as they are released. SMT is a package proxy system that is integrated with Customer Center and provides key Customer Center capabilities.
Before you configure the appliance with SMT, ensure that you meet the following prerequisites:
Get the Customer Center credentials to get Sentinel updates. For more information about getting the credentials, contact Technical Support.
Ensure that SLES 11 SP3 is installed with the following packages on the computer where you want to install SMT:
htmldoc
perl-DBIx-Transaction
perl-File-Basename-Object
perl-DBIx-Migration-Director
perl-MIME-Lite
perl-Text-ASCIITable
yum-metadata-parser
createrepo
perl-DBI
apache2-prefork
libapr1
perl-Data-ShowTable
perl-Net-Daemon
perl-Tie-IxHash
fltk
libapr-util1
perl-PIRPC
apache2-mod_perl
apache2-utils
apache2
perl-DBD-mysql
Install SMT and configure the SMT server. For more information, see the following sections in the SMT documentation:
SMT Installation
SMT Server Configuration
Mirroring Installation and Update Repositories with SMT
Install the wget utility on the appliance computer.
Perform the following steps to configure the appliance with SMT:
Enable the appliance repositories by running the following commands in the SMT server:
smt-repos -e Sentinel-Server-8-OS-Updates sle-12-x86_64
smt-repos -e Sentinel-Server-8-Prod-Updates sle-12-x86_64
smt-repos -e Sentinel-Collector-Manager-8-OS-Updates sle-12-x86_64
smt-repos -e Sentinel-Collector-Manager-8-Prod-Updates sle-12-x86_64
smt-repos -e Sentinel-Correlation-Engine-8-OS-Updates sle-12-x86_64
smt-repos -e Sentinel-Correlation-Engine-8-Prod-Updates sle-12-x86_64
Configure the appliance with SMT by performing the steps in the Configuring Clients to Use SMT
section of the SMT documentation.
