RE: [Xen-users] Manage tape on guest win2k3

[Rémi BERNIER <R.BERNIER@xxxxxxxxxxx>]

Hi James and thanks for your reply,

Yes I use scsi passthrough, I have attach
my tape with the command:
# xm scsi-attach 3 6:0:6:0 6:0:6:0

But after my guest win2k3 detected a
new tape device (Quantum LTO 2) and here I have install the driver for
Windows... Maybe it's the problem !
I try to change the driver with your
driver gplpv xenscsi but Windows don't want !!!! grrr

Rémi





>I use scsi passthrough with my gplpv drivers regularly
to give Windows access to a physical tape drive. Is that what you are trying
to do?
