Technical Tip: Event log 'SSD TRIM started'

The message 'SSD TRIM started' indicates that the SSD TRIM process has been initiated. This process helps maintain the performance and longevity of solid-state drives (SSDs) by marking the invalid data blocks for deletion, allowing the drive to perform efficiently. This event does not indicate a hardware issue.

The SSD TRIM frequency can be configured from under the global configuration:

config system global

    set ssd-trim-freq [never|hourly|...]
    set ssd-trim-hour {integer}
    set ssd-trim-min {integer}
    set ssd-trim-weekday [sunday|monday|...]
    set ssd-trim-date {integer}

This event does not affect the HA until and unless the SSD fails and if the SSD failover 'set ssd-failver enable' is enabled under config system HA. The article reference to enable SSD Failover for High Availability Cluster is given below:
