RE: Moving a DVD drive owned by VIOS

["Kristopher Whitney" <whitneyk@xxxxxxxxxx>]

Here is some documentation that talks about switching with the HMC. 
Section 5.4

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
