Solution 1297805.1 : SL24/48 - WWN Set Incorrectly in Manufacturing for SL24 and SL48 Libraries

Applies to:

Sun StorageTek SL48 Tape Library - Version: Not Applicable and later [Release: N/A and later ]
Sun StorageTek SL24 Tape Autoloader - Version: Not Applicable and later [Release: N/A and later]
Information in this document applies to any platform.

Symptoms

If 2 SL24/48 libraries or their drives end up having the same WWN on a FC Switch or a host then one of the devices will most likely not be seen or configured on the system.

Cause

During an internal audit it was found that there were some SL24/48 libraries whose WWN's were incorrectly assigned to the SL24 and SL48 libraries.

During production, a single Base WWN is assigned to each library. The library builds names off of that base name to be used for each drive. Each drive requires 3 additional WWNs and the library requires at least one WWN. To insure the WWNs remain unique, the assignment of the Base WWN to each library must reserve (or skip) a quantity of sequential WWN in order to allow the library to build addition numbers to the drives.

Solution

A "Hotfix" code has been given to Oracle by HP to give to any customers that run into this issue. A request for the "Hotfix" code should be sent through the Tape Hardware Support group with an assigned SR.

Ask for the following:
SL24 - Firmware ED00
SL48 - Firmware GD30

Note: This is non-released code and is held in Special Builds firmware file.

There is no work around for this issue. The special code must be acquired to resolve this issue.
