Sure enough, this is just as long as whatever it was doing took. Upon booting Windows, I opened the HP array configuration utility (ACU) to take a look at the array.
One of our Elster branded AMI (Automated Meter Infrastructure) server’s drives was flashing amber lights. I found it interesting that the server panel did not go into alarm and the OS was not reporting a failure – only the drive showed any indication of a problem.
Upon looking into the problem, I guessed that it wasn’t actually a failure. The SMART (Self-Monitoring, Analysis, and Reporting Technology) system loaded on each SAS drive monitors the hard disk drive to detect and report on various indicators of reliability to anticipate drive failures.
The menu options that I was given only allowed me to assign the spare drives to Array A – the RAID 1 (mirror). [Tuesday, February 01, 2011 PM] — Balaji Makams C says: Ian, if the online spare drive is configured than it will automatically start rebuilding if there is a drive failure in the array.
