RE: Moving a DVD drive owned by VIOS

Here is some documentation that talks about switching with the HMC.

On our box we have the adapter owned by vios and exposed as a virtual
adapter. To move it I just have to vary it off on the partition that has
it currently, disconnect it in the HMC, add it to the partition it needs
to be in, and then vary it on. It's been years since I set it up, so
don't remember the exact steps, but we have the CD drive and a tape drive
set up that way, and it takes about a minute to move them between our two
LPARs

Yes, I'm moving the drive from one i lpar to the other. Normally when I
clone multiples like this, I do all the installs from a tape backup of
the first one,but this particular box is a production with just 2 lpars
and it isn't connected to the VTL yet... hence I'm using the DVD drive. I
was mainly hoping when one does have to move a DVD drive from one lpar to
another, there was a little nicer way of doing it than SST and IPLing the
IOP - yuk!

Dana,
Are you attempting to move the dvd from one Client LPAR to another Client
LPAR or from one VIOS to another VIOS?
As Rob said, it's better to work with images from IBM i or if that's not
possible to work with the virtual dvd from VIOS where you can have a
virtual DVD for each partition. Now, if you need direct DVD to a VIOS for
upgrade or something like that you can always assign the USB controller to
that LPAR and just use a portable dvd. I've done that to install vios in
some cases...
But in reality for fixes and upgrades i always end up ftp-ing the data and
running from disk.

Best Regards,
Roberto

Also referenced in IBM PowerVM Virtualization Introduction and
Configuration SG24-7940:

16.2.3 Virtual optical
A DVD or CD device assigned to the Virtual I/O Server partition can be
virtualized for shared use by the Virtual I/O Server's client

partitions.

Figure 16-25 shows the Virtual I/O Server and client partition virtual
SCSI setup for the shared optical device with the Virtual I/O Server
owning the physical optical device and virtualizing it by its virtual
SCSI server adapter in slot 90 configured for Any client partition can
connect.

<Figure 16-25 SCSI setup for shared optical device>

Only one virtual I/O client partition can have access to the drive at
a time like shown in Figure 16-25 for the DB_server partition
currently accessing the virtualized optical device. The advantage of a
virtual optical device is that you do not have to move the parent SCSI
adapter between virtual I/O clients, which might even not be possible
when this SCSI adapter also controls the internal disk drives on which
the Virtual I/O Server was installed.

Attention:
The virtual drive cannot be moved to another Virtual I/O Server
because client SCSI adapters cannot be created in a Virtual I/O
Server. If you want the CD or DVD drive in another Virtual I/O Server,
the virtual device must be unconfigured and the parent SCSI adapter
must be unconfigured and moved using dynamic LPAR as described in IBM
PowerVM Virtualization Managing and Monitoring, SG24-7590.



Is there somewhere that the better approach is documented?

Dana

Dana,

If you have separate VSCSI server and client pairs for each lpar you
should only have to do step 1 to vary off the optical device. Then
you can go to the HMC or VIOS and change ownership of the DVD drive.
The steps below imply you have only one virtual scsi server adapter
that is configured to accept any virtual scsi clients. This is not
recommended since it is hard to control who has connected to that
vscsi server adapter since only one can be connected at a time. Can
you share where you found this documentation?

Thanks

Kris Whitney

We're setting up a new production box with VIOS. Did install and
maintenance on one LPAR now need to move the DVD drive to the other

LPAR.

Is this still the only way to remove a VIOS owned virtualized DVD
drive from one lpar to move it to another? Really?

Deallocating a shared virtual optical device on IBM i To deallocate a
shared virtual optical device, complete these steps:
1. Use the following VRYCFG command to vary off the optical device
from IBM i:
VRYCFG CFGOBJ(OPT01) CFGTYPE(*DEV) STATUS(*OFF) 2. To release the
optical device with its virtual SCSI connection to the virtual SCSI
server adapter for use by another Virtual I/O Server client partition,
disable its virtual IOP from the SST Hardware Service Manager. Locate
the logical resource for the virtual IOP, and select the I/O debug

option.

3. Select the Reset I/O processor option, as shown in Figure 9-4.
