Hi,
I want to change from vscsi to npiv. Is it possible to use both on the same adapter, so we can change the systems one by one, or must we place a second FC adapter in the VIO servers?
Thanks,

kmknod(8) System Manager's Manual kmknod(8)
NAME
kmknod - Creates device special files for static kernel layered products
SYNOPSIS
/sbin/kmknod
DESCRIPTION
The kmknod command obtains information from a running kernel and determines if any device special files must be created for use by the ker-
nel layered products that are statically configured.
To enable kmknod to create device special files, the statically configured kernel layered products must have been registered with the kreg
command.
Note
To create device special files for the kernel layered products that are loadable modules, such as loadable device drivers, use the cfgmgr
command instead of the kmknod command.
The kmknod command first deletes any files that have matching names and any files that have both matching major numbers and matching device
types (block or character). After any matching files are deleted, the kmknod command creates all the required device special files.
The /etc/inittab file contains instructions to invoke the kmknod command at boot time.
You must be superuser to invoke the kmknod command.
FILES
Provides the init program with instructions for creating and running initialization processes.
