Is physical disk 5 the 860? Your log has a lot of entries on disk 5 for SAS discovery. It looks like the drive isn't responding to discovery, the PERC times out, then we see the internal device reset. for port 0. I'd hazard a guess that most of your drives are going to be connected to port 0, so when that port gets reset to try to complete the discovery event repeating in the logs it would affect logs for the other disks. I'm not seeing anything that would normally jump out as a concern, though.
Hello! We are noticing more frequent "Disk X in Backplane 1 of Integrated RAID Controller 1 was reset" notices. We have 7 drives in a RAID6. Out of those 6 are Samsung 850s and one is a 860. The 860 was recently installed due to a failed drive. It seems like these notices have been happening since they 860 was installed but it may just be a coincidence. We get the notice for the disk that was replaced at least once a week. Less frequently, we will see the notice reference other disks as well. The notification says it is part of normal operation but the frequency of it has us a bit concerned. All seems to be running just fine, though. Any thoughts? Can this truly be ignored or is this a sign of something more serious? We are using a PERC H710 Mini. Firmware is 21.3.5-0002 (latest).
