4.7.8 Manual Selection of FC Topology
Under certain configurations, it may be desired to force the selection of FC
topology and disable the auto detect mechanism in the FC adapter. This
can be done on a port-by-port basis by using the following procedure.
Note: It should not be necessary to change from automatic
detection of topology. Also, firmware version 1.00.03 is the
earliest version to support this functionality.
The following is an example of how to select a manual topology N_Port
or NL_Port on a selected FC port.
Select the controller you want to modify, as follows:
ok show-disks
a) /pci@1f,0/pci@1/IntraServer,fc@2/disk
b) /pci@1f,0/pci@1/IntraServer,Ultra2-scsi@1/disk
c) /pci@1f,0/pci@1,1/ide@3/cdrom
d) /pci@1f,0/pci@1,1/ide@3/disk
e) /pci@1f,0/pci@1,1/ebus@1/fdthree@14,3203f0
q) NO SELECTION
Enter Selection, q to quit: a
/pci@1f,0/pci@1/IntraServer,fc@2/disk has been selected.
Type ^Y ( Control-Y ) to insert it in the command line.
e.g. ok nvalias mydev ^Y for creating devalias mydev for
/pci@1f,0/pci@1/IntraServer,fc@2/disk
ok select /pci@1f,0/pci@1/IntraServer,fc@2
Then enter commands as shown in the following example:
ok show-topology
Topology selected is auto
Current topology is unknown (no link)
ok set-topology <-Command with no options provides help
usage is set-topology
topology = 1 NL_Port
topology = 2 N_Port
topology = a auto
