The device name reported by the enclosure is longer than firmware allowed and result truncation, so you can not identify which drive have this error based by this event. You can check the drive status of each member to find out the unstable member. the timeout error count in the drive status page of unstable drive should be non-zero. You can consider to update controller’s firmware with the latest version in our web site. We had added filter for device name in newer versions to avoid this kind of string truncation issue.
