We believe that there are a lot of situations guest domain would like to issue SCSI command. In the near future, we will post the new version of pvSCSI driver described below. - Integrate source code of pure SCSI functions and FC transport layer functions - Support reset function - And fix some bugs Thanks kama@jp.fujitsu.com On Tue, 18 Sep 2007 13:20:47 +0800 Aaron Dailey wrote: > Kamada-san and all, > > We're also working on an NPIV driver for Solaris xVM (see > http://www.news.com/8301-13580_3-9778296-39.html for what xVM means). > > I've looked at the pvSCSI split driver, and I think it's valuable for > both NPIV FibreChannel and standard SCSI environments.
