Locating the correct drive isn't hard but make sure one is positive.  Calling NetApp for assistance might actually do more harm than good as that support person might not know either.

The hard drive numbering starts at 0, not 1, both in the software and physically.  Each shelf contains five drawers, the drawers are numbers 1 through 5, the top drawer is number 1 the bottom drawer is number 5.  Each shelf contains twelve drives, so drawer #1 contains drives 0 through 11, drawer #2 contains drives 12 through 23, and so on. The 60th drive is actually #59. 

The system and OnCommand will email and alert stating where the drive is.  IE: "FILESYSTEM DISK FAILED Shelf 0, Drawer 5, Slot 6, Bay 54"  The system is correct, kind of, the failed drive in this case is in the 5th drawer, in the 6th position, and is number 54.  

Unlike other NetApp shelves the "blink drive" command is only mildly useful.  With this shelf it will only blink the drawer, not the drive bay indicator; so the blink command only tells us what drawer it is in.  Despite the CDOT operating system needs the drive bay parameters.  Likewise there is no way to know where the failed drive on the system is just by looking at it.

storage disk set-led -disk 4.0.54 -action off  <--turns off the LED's

storage disk set-led -disk 4.0.54 -action blink -duration 5  <--turns on the shelf light indicator on for 5 minutes

(note amber light on the bottom shelf)

Log into OnCommand go to  Storage->Aggregates & Disks->Disks->Inventory; Filter the Container type by "broken", make note of the serial number of the failed drive.  Now physically go to the drive shelf, open the drawer (email alerts will be sent out), located the failed drive.  Make note of the drive layout drive layout picture on the front of the shelf.  Front left, is drive #0, drive #11 is back right.  In our example it is the 6th position, so front row, three over.  Confirm the proper drive is chosen by looking at the serial number.  If it matches remove it from the shelf, let the system sit for a minute; long enough for OnCommand to recognize the failed drive is gone.  Once it is gone from the Inventory screen, install the new drive, and assign it to a shelf.
