Obtaining drive box and drive numbers (for VSP E590, VSP E790, or VSP E1090 with the expansion drive box)

Perform the following procedure to obtain the HDD location corresponding to a reference code.

1. Extract the last four digits of a reference code (in hexadecimal).
   For example, if the reference code is “4347DA”, the last four digits “47DA” is extracted.
2. Replace the last digit with “x”.
   For example, “47DA” is converted to “47Dx”, and “B7C3” is converted to “B7Cx”.
3. If the first digit is an even number, replace that digit with “0”. If the first digit is an odd number, replace that digit with “1”.
   • For example, “47Dx” is converted to “07Dx” because the first digit “4” is an even number.
   • For example, “B7Cx” is converted to “17Cx” because the first digit “B” is an odd number.
4. In the tables in the following Reference tables, search for the four-digit character string obtained in step 3.

   Check and take note of the corresponding DB number (in decimal) and value to be added to the HDD number (in decimal).

   For example, if the four-digit character string obtained in step 3 is “07Dx”, search the table for “07Dx”.

   • The DB number can be found at the leftmost of the row (in the DB number column).

     For example, if the four-digit character string is “07Dx”, the DB number is “65” (in decimal).

   • The value to be added to the HDD number can be found at the top of the column.

     For example, if the four-digit character string is “07Dx”, the value to be added to the HDD number is “16” (in decimal).

5. Convert the last digit of the reference code in step 1 from hexadecimal to decimal.
   For example, if the reference code is “4347DA”, the last digit “A” (in hexadecimal) is converted to “10” (in decimal).
6. Calculate the HDD number.

   Add the “value to be added to the HDD number” that you took note of in step 4 to the decimal number obtained in step 5.

   For example, if the decimal number obtained in step 5 is “10” and the value to be added to the HDD number that you took note of in step 4 is “16” (in decimal), you can add both and obtain “26” (in decimal).

7. Apply the DB number (in decimal) you took note of in step 4 and the HDD number (in decimal) obtained in step 6 to the following equation:

   HDD-location-number = "HDD" + DB-number(in decimal) + "-" + value-obtained-in-step6(in decimal)

   For example, if the DB number is “65” (in decimal) as obtained in the example in step 4 and the HDD number is “26” (in decimal) as obtained in the example in step 6, the HDD location number is HDD65-26.
