When did you plug the cable back in?
(around 360 seconds), then a second error/recovery (no action on my part
to trigger this). The disk writes resumed within about 5-10 seconds of
this second recovery.
What kernel is this with?
And are you using the kernel modules that come with the kernel or the
ones that come with the open-iscsi tarball from kernel.org or
open-iscsi.org?
And did could also enable the libiscsi debugging:
echo 1 > /sys/module/libiscsi/parameters/debug_libiscsi_eh
echo 1 > /sys/module/libiscsi/parameters/debug_libiscsi_session
echo 1 > /sys/module/libiscsi/parameters/debug_libiscsi_conn
If you do not have those files, then you are using a older kernel and
there might just be a debug_libiscsi file so do:
echo 1 > /sys/module/libiscsi/parameters/debug_libiscsi
