How can I "recognize" physical drives?

[Rhinox]

If one of drives in raid-array fails, how can I say which one is it? I mean, physically, so that I replace really the failed one.

I have raid-controller with 2x SFF-8087 ports (vertical). In each of them are SFF-8087/4xSATA cables, with lines marked as P0, P1, P2, P3. Right now, I have only 4 disks, so PD-list is quite short:

Because I can follow cables in my server I know those two Samsung-drives are attached with cable to SFF-8087 closer to slot-bracket (back side of the server), with cables marked P0 and P1. But which one is which?

Insert them at different times and make a note.

Or else pull the serial numbers from the ones that work and eliminate them.

Which raid controller?

It should give you WWN numbers of the drives in the bios... Or at least serial numbers?

Write/read to/from all the remaining drives and check the activity LEDs.

I can do no "destructive" testing (like pull one out and see what contoller says, then you know which one it was), because those drives are already running in server. But I turned server off and checked those Samsung-drives: there are two different numbers on them:

"S/N" (suppose it is "serial number") and "WWN" (do not know what this mean), both ~15 chars long. How can i get these numbers using StorCLI/MegaCLI? Controller is M5016...

 

[Stanza]

Not knowing m5016 controller bios.... But usually you

Boot into controller bios

Select sas topology

Drill down to individual ports

Should show drive info, which then you can work out which drive is on which port .... And find your bad drive from there.

Eg, to find a dead drive....write down all drives found in bios and their serial numbers or WWN numbers....

The dead drive is the one not recognized in bios
