5.5.8 Manual Selection of FC Topology
Under certain configurations, it may be desired to force the selec-
tion 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.
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 <topology> set-topology
NOTE:
NOTE:
It should not be necessary to change from automatic detection
of topology. Also, firmware version 1.00.03 is the earliest ver-
sion to support this functionality.
