SL3000 - How can the WWN be Calculated / Defined for each drive bay?

Solution

It is sometimes necessary to provide the drive WWNN and WWPN information to a customer before drives are physically installed in the library. The following information should provide the necessary information to calculate the addresses of the new drives in advance.

Each drive bay is assigned a static set of WWNs using the base serial number to create a seed value for the WWNNs and WWPNs of the SL3000 FC ports and all the drive bays. The first part of the address "50:00:04" was assigned to StorageTek for all their products. It is now assigned to Oracle but the StorageTek tape product line still uses this range. The parts near the end are the assigned values. Each bay is assigned 3 values, a WWNN and 2 WWPNs. The easiest way to get the values is to run the SL3000 Drive Details Spreadsheet (Excel only). See attached file, instructions are in the second tab of the spreadsheet.

To just get the WWNs, obtain the "Drive Details" report from the SL3000 in HTML format. Start the spreadsheet and enter "Control- i" and it will prompt you to "Enter Header Data" and reply "No" and it will then ask for the Drive Details file. After it runs the file it will prompt you with "Fill in WWNs Now?" Say yes and it will fill in the WWNNs and WWPNs of all the slots, empty or occupied.

In the absence of the Drive Details report file you can open the spreadsheet and enter the WWNN of any installed drive into the spreadsheet into the corresponding Bay location's "WNNN" field and press
"Control - W" and it will populate all the WWNNs and WWPNs.

You can also manually calculate the addresses.

The WWNN that is assigned to the Base library can be displayed with the SLConsole. The Drive Bay addresses begin with a value that is 10 hex higher. The WWN assignments then follow a pattern that starts with Drive Bay 1 and runs through Bay 56. Each bay has a WWNN, WWPN1 and WWPN2 assigned. Each subsequent bay has a WWNN assigned that is 3 higher than the privious bay. Remember that each bay is assigned 3 addresses.

Look at the following example:
If the WWNN for the Base SL3000 obtained from the SLConsole is 50:01:04:F0:00:AE:26:E7, then add 'x10' to get 50:01:04:F0:00:AE:26:F7 and that would be the address of Bay 1.
WWNNs and WWPNs would then be assigned as follows:

Bay 1 WWNN is 50:01:04:F0:00:AE:26:F7 (Base address plus 'x10')
Bay 1 WWPN1 is 50:01:04:F0:00:AE:26:F8
Bay 1 WWPN2 is 50:01:04:F0:00:AE:26:F9

Bay 2 WWNN is 50:01:04:F0:00:AE:26:FA (3 higher than previous bay's WWNN)
Bay 2 WWPN1 is 50:01:04:F0:00:AE:26:FB
Bay 2 WWPN2 is 50:01:04:F0:00:AE:26:FC

Bay 3 WWNN is 50:01:04:F0:00:AE:26:FD
Bay 3 WWPN1 is 50:01:04:F0:00:AE:26:FE
Bay 3 WWPN2 is 50:01:04:F0:00:AE:26:FF
...
Bay 56 WWNN is 50:01:04:F0:00:AE:27:9C
Bay 56 WWPN1 is 50:01:04:F0:00:AE:27:9D
Bay 56 WWPN2 is 50:01:04:F0:00:AE:27:9E
