You seem to lack a solid understanding how all the virtualisation works:

First you create a virtual SCSI adapter on the VIOS and allow a certain LPAR to use it. For the LPAR it is used like any physical SCSI adapter, save for the fact that it is just a software construct in the VIOS. You do this on the HMC (see here), then run cfgdev on the VIOS.

Next you create (virtual) SCSI-devices on the VIOS: see the command "mkvdev" on the VIOS for creating such devices. You create such a device by assigning a "backing device" (some disk space the VIOS can control) and connect it to a virtual SCSI adapter.

For instance:

Code:

mkvdev -vdev hdisk10 -dev vtdisk_lpar5 -vadapter vhost5

This means: take "hdisk10" on the VIOS and use it(s disk space) to create a virtual disk "vtdisk_lpar5", which is connected to a virtual SCSI adapter named "vhost5". If "vhost5" is connected to the "lpar 5" you can run the cfgmgr command there and the newly connected disk would appear.

I hope this helps.

Migrating hdisks from vscsi to NPIV with powerpath

Hi All, I'm preparing to migrate some servers from vscsi to pass-thru NPIV. I am planning to have the SAN team move the exact LUNs from vio1/vio2 to those two VWWN through NPIV. My question is on the partition itself.. right now, let's say I have hdisk0/1/2/3/4 that are part of datavg. They...

Vscsi and npiv on same adapter

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, Ronald

NAME

     nsp -- Workbit Ninja SCSI-3 based PC-Card SCSI host adapter driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel configuration file:

           device scbus
           device nsp

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

           nsp_load="YES"

DESCRIPTION

     The nsp driver provides access to the SCSI bus connected to a PC-Card SCSI host adapter based on a Ninja SCSI-3 controller by Workbit.

HARDWARE

     Controllers supported by the nsp driver include:

     o   Alpha-Data AD-PCS201
     o   I-O DATA CBSC16

SEE ALSO

     cd(4), ch(4), da(4), intro(4), pccard(4), sa(4), scsi(4)

HISTORY

     The nsp driver has been developed for NetBSD/pc98 and ported for FreeBSD.  It first appeared in FreeBSD 3.4 with PAO3 and merged in
     FreeBSD 4.2.

AUTHORS

     The nsp driver was written by Naofumi HONDA.

     This manual page was written by Noriaki MITSUNAGA <non@FreeBSD.org> and Hideyuki KURASHINA <rushani@FreeBSD.org>.

BUGS

     SMIT mode is only supported under OLDCARD now.
