For the last 2 mornings I have an HP Prolient DL 380 G5 with 8 drives.. One of the drives (bay 6) goes offline/missing. I then have to go into HP Array Config and re-attach the drive. Once I re-attach the drive everything is OK, until the next morning at 4:30am. I have looked in the event logs and do not see anything that sticks out. I have updated the controller's firmware and drivers and the issue continues. Has anyone seen this? Are there any tools that I could use to check loads etc at that particular time?
