You need to calculate the storage array name only one time, even if you have more than one device on the storage array.
Note
This calculation only applies to the old HPE 3PAR storage array models that don't have WWN identifiers mentioned in the array software. For the new models, you can directly find the WWN identifier in the System details section of the array software.
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 HPE 3PAR StoreServ 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.
