Calculating the Storage Array Name for HP 3PAR Storage Arrays

You need to calculate the storage array name only one time, even if you have more than one device on the storage array.

Before You Begin

To calculate the storage array name, use the World Wide Name (WWN) of any volume in the storage array.

Procedure

To get the WWN identifier, complete the following steps from the HP 3PAR Management console:

  • If you have an 8-byte WWN, use the following formula:

    2FF7000 + WWN.substr(4,3) + 00 + WWN.substr(12,4)

    where:

    • WWN.substr(4,3) is the next 3 digits after the fourth digit of the WWN identifier
    • WWN.substr(12,4) is the next 4 digits after the twelfth digit of the WWN identifier

    Example

    WWN = 50002AC0012B0B95

    2FF7000 + 2AC + 00 + 0B95

    The storage array name is 2FF70002AC000B95.

  • If you have a 16-byte WWN, use the following formula:

    2FF7000 + WWN.substr(4,3) + WWN.substr(26,6)

    where:

    • WWN.substr(4,3) is the next 3 digits after the fourth digit of the WWN identifier
    • WWN.substr(26,6) is the next 6 digits after the twenty sixth digit of the WWN identifier

    Example

    WWN = 60002AC5000000000000052200000B95

    2FF7000 + 2AC + 000B95

    The storage array name is 2FF70002AC000B95.
