Re: Removing drives from a guested lpar.

[DrFranken <midrange@xxxxxxxxxxxx>]

You CAN vary off the NWSD that has the drives you want to remove while 
the guest is operating ** BUT ONLY ** if you are removing ALL the drives 
on that NWSD and they are already removed from the ASP on the guest.

If any drives on that NWSD are still active to the guest then you'll get 
A600xxxx on the guest.
