2 What are WWNNs and WWPNs? A WWNN is a World Wide Node Name; used to uniquely identify a device in a Storage Area Network (SAN). Each IBM Storage device has its own unique WWNN. For DS8000, each Storage Facility Image (SFI) has a unique WWNN. For SVC and Storwize V7000, each Node has a unique WWNN. A WWPN is a World Wide Port Name; a unique identifier for each Fibre Channel port presented to a Storage Area Network (SAN). Each port on an IBM Storage Device has a unique and persistent WWPN. IBM System Storage devices use persistent WWPN. This means if an HA (Host Adapter) in an IBM System Storage Device gets replaced, the new HA will present the same WWPN as the old HA. IBM Storage uses a methodology whereby each WWPN is a child of the WWNN. This means that if you know the WWPN of a port, you can easily match it to the WWNN of the storage device that owns that port. A WWPN is always 16 hexadecimal characters long. This is actually 8 bytes. Three of these bytes are used for the vendor ID. The position of the vendor ID within the WWPN varies based on the format ID of the WWPN. To determine more information we actually use the first character of the WWPN to see which format it is (the vendor ID position is highlighted in red): 1 = IEEE 803. standard format (example 10:00:00:00:c9:f:65:d6 ß this is an Emulex HBA WWPN since Emulex owns the 0000c9 company ID. = IEEE 803. extended format (example: 1:00:00:e0:8b:90:90:04 ß this is a Qlogic HBA WWPN since Qlogic owns the 00e08b company ID. 5 = IEEE Registered Name format (example 50:05:07:63:00:c7:01:99 ß this is an IBM WWPN since IBM owns the company ID. An example of a Registered Name Format WWPN is 50:05:07:63:00:c7:01:99. We know this WWPN uses the Registered Name Format because it starts with a 5. This format can be broken down into 3 sections: Section 1 Format ID Section Vendor ID Section 3 - Vendor Unique 5 0:05:07:6 3:00:c7:01:99 Vendor ID is registered to IBM (formerly registered to XIV). Vendor ID is registered to IBM. Vendor ID 00A0B8 is registered to Symbios Logic, now owned by NetApp, who manufacture the DS3000, DS4000 and DS5000. Vendor ID 0080E5 is registered to LSI Logic, but is used by NetApp, who manufacture the DS3000, DS4000 and DS5000. There are literally 1000 s of company IDs registered with the IEEE.

WWPN is based on: 0:0Z:00:A0:B8:xx:xx:xY If Z =, 4, 6 or 8 then this port is on controller A (this will be the same as the Z in WWNN) If Z = 3, 5, 7 or 9 then this port is on controller B (this will be 1 greater than the Z in WWNN) The Y value is based on the WWNN. If in WWNN, Y=0 then port 1 = 1 and port = If in WWNN, Y=D, then port 1= E and port = F The table to the left shows the pattern.

7 DS4800 WWPN Determination WWNN is based on: WWPN is based on: 0:04:00:A0:B8:xx:xx:xx 0:YZ:00:A0:B8:xx:xx:xx The Y value is the port number. For DS4800 this is 1 to 4. If Z = 4 then the port is on controller A If Z = 5 then the port is on controller B The numbers shown in the boxes are YZ numbers (port/controller) So the top right hand port contains 14 meaning the WWPN for that port is 0:14:00:A0:B8:xx:xx:xx and the port is port 1 on Controller A Page 7

8 IBM Storage Systems WWPN Determination Version 6.6 DS500 WWPN Determination WWNN is based on: 0:0Z:00:80:E5:xx:xx:xx WWPN is based on: The Y value is the port number. 0:YZ:00:80:E5:xx:xx:xx If Z = 4 or 6 then the port is on controller A If Z = 5 or 7 then the port is on controller B The numbers shown in the boxes are YZ numbers (port/controller) For DS500 this is 1 to 4 (note: ports 3 and 4 are an optional feature). So the upper right hand port on controller A contains 14 meaning the WWPN for that port is 0:14:00:80:E5:xx:xx:xx and it is port 1 on controller A ID/Diag Port Port 1 P Ch1 FC Drive Channels (Ch) Ch1 P Ch4 Ch4 Ch3 Ch Ch Ch1 FC Host Channels (Ch) Ch1 Ch Ctrl A Ctrl B DC OK B A FC Host Channels (Ch) AC A B AC A B OK DC Ctrl B Ctrl A FC Host Channels (Ch) Ch1 Ch Ch1 Ch 15 5 FC Host Channels (Ch) Ch3 Ch4 Ch3 Ch FC Drive Channels (Ch) Ch1 P1 Ch1 P Port 1 Port ID/Diag Page 8

9 DS5100 and DS5300 WWPN Determination WWNN is based on: 0:0Z:00:A0:B8:xx:xx:xx where xxxxxx is unique for each machine WWPN is based on: 0:YZ:00:A0:B8:xx:xx:xx where xxxxxx is unique for each machine The Y value is the port number. For DS5000 this ranges from 1 to 8. If Z = 4 or 6 then the port is on controller A If Z = 5 or 7 then the port is on controller B In the examples on the next page, the numbers shown in the boxes are YZ numbers (port/controller) So the upper right hand port contains 16 meaning the WWPN for that port is 0:16:00:A0:B8:xx:xx:xx and it is port 1 on controller A Page 9

17 DS8800 Eight Port Host Adapters The DS8800 is different to earlier models in that it supports host adapters with eight ports. The DS8800 also supports host adapters with four ports. The maximum port count for a DS8800 remains 18 ports (which is the same as earlier models). The maximum host adapter count for a DS8800 is 16 (which is less than earlier models which support 3) Only slots C1 and C4 in each enclosure are used for host adapters Where a four port host adapter is used, only the top 4 ports will be present on that card. Note that for the eight port card, when an ESS800/DS8100/DS8300 connects to the lower four ports of the eight port card, the SAID it will report will NOT be the same as the IOport number. These special SAIDs are documented in Techdoc TD10586 which can be found here: Page 17

20 DS8800 (post Dec 011) and DS8870 Machines built starting mid December 011 will use slightly different WWPNs. The three digit segment of the WWPN that identifies each port will be 1 higher. This means for instance where port I0300 on an older machine had a WWPN segment of 18:0 on a new machine it will be 18:1 This means for instance where port I0301 on an older machine had a WWPN segment of 18:4 on a new machine it will be 18:5 This means for instance where port I030 on an older machine had a WWPN segment of 18:8 on a new machine it will be 18:9 This means for instance where port I0303 on an older machine had a WWPN segment of 18:C on a new machine it will be 18:D This change will also affect DS8700s built after December 011. This change does not affect existing machines, only machines shipped new from plant after mid December 011. All DS8870s will use the new numbering Page 0

25 SAN Volume Controller (SVC 145) WWPN determination WWNN is based on 50:05:07:68:01:0x:xx:xx where x:xx:xx is unique for each machine WWPN is based on: 50:05:07:68:01:Yx:xx:xx where x:xx:xx is unique for each machine and the Y value is taken from the port position. The number in each box is the Y value. Port numbers (used for servicing) are always sequentially numbered left to right (viewed from the rear of the node) So for example port 1 the left hand most port, contains a 4, so a WWPN presented by this port would look like: 50:05:07:68:01:4x:xx:xx Port 1 Port Port 3 Port F or 145-8F (8F hardware shown) Page 5

26 SAN Volume Controller (SVC 145) WWPN determination The number in each box is the Y value.

27 Storwize V3700 (07-LC/SC) WWPN determination The Storwize V3700 consists of two node canisters. The WWNN of each node canister will be based on 50:05:07:68:03:00:xx:xx where xx:xx is unique for each node canister. It is unrelated to the WWNN of the other node canister though the last number of the two WWNNs are normally sequential. The FC cards in each canister are optional. The WWPN is based on: 50:05:07:68:03:YY:xx:xx where xx:xx is unique for each node canister and the YY value is taken from the port position. Note that the two canisters are side by side. The numbers shown in the image below are the YY value. The ports are numbered 1-4, left to right. So for example, port 1 (left hand most port), contains a 04, so a WWPN presented by this port would look like: 50:05:07:68:03:04:xx:xx. To display the WWPNs, use the CLI command lsportfc as shown below.!!!!!

28 Storwize V7000 (076-11/14/31/34) WWPN determination The Storwize V7000 consists of two node canisters. The WWNN of each node canister will be based on 50:05:07:68:0:0x:xx:xx where x:xx:xx is unique for each node canister. It is unrelated to the WWNN of the other node canister though the last number of the two WWNNs are normally sequential. The WWPN is based on: 50:05:07:68:0:Yx:xx:xx where x:xx:xx is unique for each node canister and the Y value is taken from the port position. Note that the lower canister is upside down in relation to the upper canister. The number in each black box is the Y value. It is also the port number, This means the Y value and the port number are the same number (unlike the SVC). So for example, port 1 (the upper left hand most port), contains a 1, so a WWPN presented by this port would look like: 50:05:07:68:0:1x:xx:xx. Upper node canister(1) Lower node canister() Page 8

29 XIV (810/81 - A14) WWPN Determination Generation WWNN Determination WWNN format is 50:01:73:8x:xx:xx:00:00 where x:xx:xx is the 5 digit XIV serial number in hexadecimal. This means if you know the XIV serial number, you can convert it from the 5 digit decimal number to hexadecimal and determine the WWNN. WWPN Determination WWPNs will be in the format: 50:01:73:8x:xx:xx:RR:MP where x:xx:xx is the 5 digit XIV serial number in hexadecimal and: RR: Rack ID (currently always 01) M: Module ID (4 to 9) P: Port ID (0 to 3) In the diagram to the right, the MP value (Module/Port) which make up the last two digits of the WWPN) is shown in red. The diagram represents the patch panel found at the rear of rack 1. Hardware Dependencies There are two Fibre Channel HBAs in each XIV module. Ports 1 and are on the left hand HBA. Ports 3 and 4 are on the right hand HBA.

This means if you know the XIV serial number, you can convert it from the 5 digit decimal number to hexadecimal and determine the WWNN. WWPN Determination WWPNs will be in the format: 50:01:73:8x:xx:xx:RR:MP where x:xx:xx is the 5 digit XIV serial number in hexadecimal and: RR: Rack ID (currently always 01) M: Module ID (4 to 9) P: Port ID (0 to 3) In the diagram to the right, you can see the module numbers and port numbers. The diagram represents the patch panel found at the rear of rack 1 of an XIV Gen3. You will note the ports are physically numbered 1 to 4 but the WWPN port numbers go from 0 to 3. This means that: - a WWPN that ends in 0140 is rack 1, module 4, port 1 - a WWPN that ends in 0143 is rack 1, module 4, port 4.
