IBM 5.01 ok /pci@1f,4000/lpfc@2 select-dev ok set-fc-al ok unselect-dev, ok reset-all, Page

To set the topology back to loop (if the HBA is connected to a hub), enter these commands.

ok" /pci@1f,4000/lpfc@2" select-dev

ok set-fc-al

ok unselect-dev

ok reset

By default, the topology is set to auto-FCAL. To set auto topology with public or private loop first, enter these commands.

ok" /pci@1f,4000/lpfc@2" select-dev

ok set-auto-fcal

ok unselect-dev

ok reset-all

To set auto topology with point-to-point first, enter these commands.

ok" /pci@1f,4000/lpfc@2" select-dev

ok set-auto-ptp

ok unselect-dev

ok reset-all

7.Determine the device: WWPN, DID, or AL_PA. ok probe-scsi-all

Make note of the actual DID, WWPN, or AL_PA and the corresponding boot entry.

8.Set the boot device ID.

ok" /pci@1f,4000/lpfc@2" select-dev

ok [wwpndidalpa] [lun] [target id] set-boot-id ok unselect-dev

where [wwpndidalpa] - enter the device WWPN (point to point), DID (public loop), or ALPA (private loop).

[lun] - enter the LUN number in hex. To enter the decimal LUN number, enter d# [lun].

[target id] - enter the target id in hex. To enter the decimal target ID, enter d# [target id]. For example, with alpa=e1, lun=100 (decimal) and target id=10 (decimal):

ok did e1 d# 100 d# 10 set-boot-id

9.Boot to the original local disk to set up the newly defined Fibre Channel disk. ok boot [local disk]

where [local disk] - enter the complete path or the alias of the original boot disk.

Note: If the Fibre Channel disk is not found when the system is rebooted, enter "touch / reconfigure" and reboot. If the disk is still not discovered, edit the "/kernel/drv/ lpfc.conf" file and change the topology from 4 to 2 or reverse. It may also be necessary to add an entry for the boot drive to the sd.conf file.
