3.1.5.7 Persistent Device Naming

Under certain configurations, such as when the Fibre Channel disk is the
boot device of a system, it may be preferable to lock a target disk to a
unit number. LSI Logic Fcode allows the system administrator to write a
nonvolatile map of IDs to the Fibre Channel controller.

The following is an example of how to map devices in the persistent
device table.

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

ok show-children
