Starting out in iSCSI - recovery questions / options from target vanishing...

[Karl Pielorz]

Hi,

I've been looking at setting up iSCSI on my home network. I have a windows 
machine, which I've installed iSCSI target software on, and set it up.

I'm using FreeBSD 7.2-STABLE - and I've setup iSCSI as an initiator on that.

At the end of the day, I get the following logged when I've finished 
setting it up:

"
Jan 12 20:25:30 test kernel: da0 at iscsi0 bus 0 target 0 lun 0
Jan 12 20:25:30 test kernel: da0: <CCDISK iSCSI Cake > Fixed Direct Access 
SCSI-4 device
Jan 12 20:26:21 test kernel: GEOM_LABEL: Label for provider da0s1 is 
ufsid/4b4cdaed5db746bf.
"

I can label, partition, format and mount da0 - and everything works fine, 
which looks pretty successful.

Until I 'break the connection' - either by restarting the windows iSCSI 
target, or pulling the network cable.

Whatever was in progress on da0 expectedly freezes. However, when the 
connection is available again - nothing seems to re-attach, continue, or 
error.

I'd guess I may be being optimistic if I expected it to re-attach, and 
continue without error - but is there any way of either avoiding the freeze 
(or raining in the timeout) - or forcing things to try to reconnect?

I don't mind getting errors, or trashing the iSCSI drive (it's only used 
for shifting backups on to large drives on the windows machine) - but as it 
is, the only way to recover is to restart the FreeBSD box.

If someone can point me in the right direction, or explain what's "meant to 
happen" that'd be great,

Thanks,
