Abstract

This article describes a method that can be used to help technicians to identify broken disk dirive to be replaced in situation when the disk is one of 100s disks in a chassis. The article also describes complete replacement procedure that is using the new disk identification and helper smartphone app that technician can use instead of logging into any workstation or console in the data center.

Method for automatic identification of disk drives to be replaced by low skilled technicians

Computer systems have to deal with storage components like disk drives that can break. If the system has 100 or more such devices they break frequently (even if a singe drive have high MTBF) and become the weakest chain in terms of reliability . Therefore it is important to have elastic and effective way of replacing disk drives that does not require highly skilled engineer . The best it would be if we can send a technician with a drive to be replaced to customer data center and he could replace
it without logging into any computer system or console in the data center - just remove broken component and insert a new one. This scenario is possible but has one issue without reliable solutions so far - if the system has 100s of disks how to tell the technician which disk to replace. This paper solves the problem.

The idea presented in this disclosure is to use location LED to broadcast special light codes that technician's smartphone can decode and used to identify the right drive to replace.

Here is the new way:


1) In the support center L2 engineer is determining which disk to replace.

2) L2 engineer is generating a replacement code (short sequence of characters)

for each disk to replace.

3) L2 engineer is placing request to the management software of the computer

system to start locating disks that are to be replaced and broadcast replacement code generated on the previous step .

4) Management software starts blinking LEDs of disks to replace in the way it is broadcasting replacement code using light signals . For instance it could use Morse code but other (maybe better) ways are also possible [exact way how to encode is not a subject of this disclosure].

5) L2 is sending technician to the data center where the computer system is located and sends replacement codes to this technician .

6) The technician on his smartphone has an application that receives the replacement codes.

7) When on site, technician is using his camera equipped smartphone with the app mentioned in the previous step to scan the computer system (using the smartphone camera).

8) The App is looking for blinking LEDs and recognises the replacement codes . Since the image of scanned system is constantly displayed on the smartphone the App hi...
