You may not get a true/reliable diagnostic test on this drive, as to properly test the drive, you need HP diagnostics, but HP diagnostics won't run on a Dell server. Likewise, it is also not surprising that the drive doesn't properly respond to the diagnostics which were written to test Dell-certified drives. Drives are 'certified' for controllers (thus, HP and/or generic Retail drives are NOT certified for use on Dell controllers), so if the controller is asking something of the drive that the drive does not understand or does not know how to respond to, then it can show up as an 'unknown' or 'illegal' request. In order for a drive to work well with that controller, it must have its firmware 'tuned' to match the settings of the controller. Dell controllers (just like any other OEM controller) has been fine-tuned and tweaked for performance and to allow Dell to support and guarantee performance and reliability. Sure, there could be a problem with the drive (as in it may be malfunctioning), but an equally likely scenario is that your drive is not compatible.

Could somebody give me some light and/or confirm this diagnostic, please? Their answer is that it could be a problem with the HDD. Warning: Could not find the Diagnostics Debug Section Header! Visually the disk seems to works normally, but this activity LED always lit is, at least, strange.Īfter contacting Dell support here in Brazil they instructed us to update the BMC, BIOS and the RAID controller firmware. Status LEDs are all ON, as they should be. We see that it blinks together with the other disks when there is a read/write activity, but it gets back to it's ON state (instead OFF, like the others). However, there is one issue: its activity LED is always lit. The array has been rebuilt and is in its optimal state. The replacement disk is from HP, the same specs, model number ST9146803SS. Original disks are all Seagate Savvio 10K.2, model number ST9146802SS. One of the disks have failed and we replaced it. We have a PowerEdge 1950 with 4 SAS disks in a RAID5 configuration.
