In order to upgrade the Cisco Security Monitoring Analysis and Response System (CS-MARS) with CD or DVD ROM, complete these steps. In this example, the upgrade is from version 4.2.2 to 4.2.3. The pkg file used for the upgrade exists on the root directory of the disc.
Note: Enable archiving on the MARS Appliance for two to three days before you perform the attempt to upgrade from the 4.2.2 to the 4.2.3 release. This precaution is strongly recommended in case reinstallation is required due to any encountered errors.
Use the reboot command in order to restart your MARS and wait 15 minutes before you continue.
The only special consideration here is that the 4.2.3 update is a very large update that includes a patch to the database system. Because of this, run through these extra items before you perform the 4.2.3 update.
Complete these steps in order to verify that your MARS Appliance does not have hard drives that are degraded or rebuilding:
One of the lines should describe the /u01 partition:
Filesystem Size Used Avail Use% Mounted on /dev/md3 16G 4.6G 10G 31% /u01
Verify at least 3 GB available is available. The example has 10 GB available. A nightly process runs to clean up any files that accumulate on this partition. If you have less than 3 GB, there is an issue with your appliance that you must resolve before you upgrade.
Insert the disc that contains the software upgrade package and issue the pnupgradecdrom:// command, where is the name of the file you downloaded and burned to the disc.
After the upgrade completes and the MARS auto restarts, wait another 15 minutes and then issue the pnupgrade log command. Make sure the last line says:
Upgrade from 4.2.2 2303 to 4.2.3 2403 finished.
When the upgrade is complete, log into the MARS GUI. Browse to Help > About section and verify your version.
