I have attempted to upgrade PAM 3.0.2 to 3.1.1. After reboot the following upgrade error message occurred.
PAM-CMN-1264: Upgrade failed. Please review the audit log and then perform a system recovery.
This is a known bug related to failure of altering kdc_server table.
If logs.bin file is collected CA Technical Support can find the following error in the installation log.
ALTER TABLE `uag`.`kdc_server`
DROP FOREIGN KEY `kdc_server_ibfk_1`
Mysql schema update of file 3.1.0_upgrade.sql failed 1, we're going to abort
