• This System log message indicates one or two faulty drives in RAID1 array (Two disks are present in RAID1 array. This configuration provides redundancy so if a drive in a RAID 1 array fails there is no service interruption or loss of log data. )
• When this System log message is seen, failure could be in any drive such as solid-state drive (SSD), hard-disk drive (HDD), Log Disk, etc.

1. Run the command "show system raid detail"
2. Check if the faulty drive is seen.
3. Once seen, generate a tech support file and open a case with Support to confirm if disk replacement is required.

Example: The output below indicates faulty SSD - disk1:
