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 HBAs 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 HBAs.
The I/O addresses of HBAs 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 : 9:00:00 PM:17:42:51:00:00 WWPN value for HBA port 2 : 10:00:00 PM: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 one port HBAs 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 two port HBAs are 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
