Restarting Redis

During a cluster reboot or possible network flux in the Red Hat® OpenShift® Container Platform environment, the Redis pods experience a deadlock and are unable to determine a leader pod. The pods appear with error Init:CrashLoopBackOff. IBM Security QRadar® Suite Software provides a method to restart RedisSentinal when pods are in a crash loop. The following action reinitializes the Redis instance.

Before you begin

Install the command-line interface (CLI) utility cpctl from the cp-serviceability pod. For more information, see Installing the cpctl utility.
