Appendix I WWN Allocation Order During HBA address rename Configuration

This section explains the order in which WWNs are allocated during configuration of HBA address rename.

With HBA address rename, as WWNs are allocated to the I/O addresses of HBA adapters in descending order, the order may not match the port order listed in the HBA.
When specifying the locations for WWN allocation, check the I/O addresses of HBA adapters.
The I/O addresses of HBA adapters can be confirmed using tools provided by HBA vendors or FC-HBA BIOS.

For blade servers

Example

For a blade server with an HBA with 2 ports, allocation is performed as follows:

WWN value provided by "I/O Virtualization Option": 20:00:00:17:42:51:00:00
WWNN value for ports 1 and 2 of the HBA -> 20:00:00:17:42:51:00:00
WWPN value for HBA port 1               -> 21:00:00:17:42:51:00:00
WWPN value for HBA port 2               -> 22:00:00:17:42:51:00:00

For rack mount or tower servers

For the PCI slots of rack mount or tower servers, WWNs are allocated in the following order:

PRIMERGY RX200 S4   slot2 -> slot1 -> slot3
PRIMERGY RX200 S5   slot1 -> slot2 -> slot3
PRIMERGY RX300 S4   slot5 -> slot6 -> slot1 -> slot7 -> slot4 -> slot2 -> slot3
PRIMERGY RX300 S5   slot2 -> slot3 -> slot4 -> slot5 -> slot6 -> slot7 -> slot1
PRIMERGY RX600 S4   slot6 -> slot3 -> slot4 -> slot1 -> slot2 -> slot7 -> slot5
PRIMERGY TX300 S4   slot5 -> slot6 -> slot1 -> slot7 -> slot4 -> slot2 -> slot3

In a single PCI slot, allocate WWNs in the following order:

port 2 -> port 1

Example

When 1 port HBA adapters are mounted in slot 2 and slot 3 of an RX600 S4, WWNs are allocated in the following order:

slot 3 -> slot 2

WWN value provided by "I/O Virtualization Option": 20:00:00:17:42:51:00:00
WWNN value for slots 2 and 3 of the HBA  : 20:00:00:17:42:51:00:00
WWPN value for HBA slot 2                : 22:00:00:17:42:51:00:00
WWPN value for HBA slot 3                : 21:00:00:17:42:51:00:00

When a 2 port HBA adapter is mounted in slot 2 of an RX600 S4, WWNs are allocated in the following order:

slot 2 (port 2) -> slot 2 (port 1)

WWN value provided by "I/O Virtualization Option": 20:00:00:17:42:51:00:00
WWNN value for ports 1 and 2 of the HBA : 20:00:00:17:42:51:00:00
WWPN value for HBA port 1               : 10:00:00 PM:17:42:51:00:00
WWPN value for HBA port 2               : 9:00:00 PM:17:42:51:00:00
