I had written....

with Windows or Linux Guests).

One thing I should clarify... in a Xenserver environment with iSCSI =
backed SR's and (mostly) Freebsd guests... In our setup we specifically =
set up iSCSI to be the link to the Xenserver Hypervisor pool's SR's. We =
do NOT have any of the guest OS's talking iSCSI. So long story short, =
freebsd will never see iSCSI in this case - only the pool of hypervisors =
does.

Again, I'd wager this is the most common type of setup for =
Xenserver/iSCSInas/FreeBSDguests.

Long story short, if for some reason the iSCSI connection is interrupted =
(someone trips over a cable, or the san crashes and reboots, etc.)... =
the windows and linux guests recover just fine. FreeBSD on the other =
hand, will generally still have the OS disk but any additional disks are =
unreadable. Thus, I'd suspect it has something to do with how freebsd =
handles disk I/O in a Xenserver environment (and has nothing to do with =
iscsi inside FreeBSD).
