# HG changeset patch

# Date 1258026044 0
# Node ID b7181e5d466611dca5aa37eaf7efe63a05ab605b

xend/xm: Add PSCSI_HBA class and DSCSI_HBA class to XenAPI
XenAPI (not xapi) has supported only LUN assignment mode for pvSCSI.
But at last, HOST assignment mode also is supported by these patches.
To support HOST assignment mode, these patches add PSCSI_HBA class
and DSCSI_HBA class to XenAPI.
