We think a hard drive is failing on a production server. I copied everything to another drive on a different array. How can we monitor the health of the hard drive/array?

Thanks. We'll let you know when a new response is added.

It depends what type of drive and array you are using. Most modern drives have SMART (Self-Monitor Analysis and Reporting Technology) and there are at least 3 versions of SMART. In its original incarnation SMART provided failure prediction by monitoring certain online hard drive activities. A subsequent version improved failure prediction by adding an automatic off-line read scan to monitor additional operations. The latest SMART technology not only monitors hard drive activities but adds failure prevention by attempting to detect and repair sector errors. Also, while earlier versions of the technology only monitored hard drive activity for data that was retrieved by the operating system, this latest SMART tests all data and all sectors of a drive by using off-line data collection to confirm the drive’s health during periods of inactivity. There are a number of different tools that can be used to obtain the status from each HD from SMART. But this generally requires direct access, as opposed to logical access which is what happens in a RAID array. With RAID arrays they will generally provide vendor specific software that can monitor and read the SMART information from each HD to predict failure.

    Some servers come with utility tools to help you to check your Hard Disk, memory, cpu, fans and etc status. If you are using dell servers it is called OMSA.

    Besides OMSA for Dell there is Insight Control fo HP is that's the case. All the above suggestions are 100% valid to answer your question. I can only suggest one more that is to verify the Log's of that server. The array controller driver must log this kind of information. HTH
