in this case i would suspect a bug in your san firmware or the leadville driver stack. this is something to try on another mashine with the same software setup. if the error can be reproduced you can try to add newer patches or a newer san firmware... maybe this fixes your "problem".

TGT-ADMIN(8) TGT Configuration Tool TGT-ADMIN(8)
NAME
tgt-admin - Linux SCSI Target Configuration Tool.
SYNOPSIS
tgt-admin -[OPTION]...
DESCRIPTION
tgt-admin is a utility which allows a persistent configuration of targets and luns.
It uses tgtadm commands to create, delete and show targets.
OPTIONS
-e, --execute
read /etc/tgt/targets.conf and execute tgtadm commands.
if target already exists it will be deleted and a new instance will be created with the new parameters instead.
-d, --delete
delete all the targets
-s, --show
show all the targets
-f, --force
don't exit on tgtadm errors
-p, --pretend
only print tgtadm options
-v, --verbose
increase verbosity (no effect in "pretend" mode)
-c, --conf <conf_file>
specify an alternative configuration file instead of /etc/tgt/target.conf, which is the default.
-h, --help
display a list of available options and exits
CONFIGURATION FILE SYNTAX
The defualt configuration file is: /etc/tgt/target.conf. It defines all the targets and their properties.
The configuration file is in XML format and uses tags. Configuration file contains several target blocks, where each block contains tar-
get's proerties such as storage devices, initator ACL and authorization information. You can include other config files using:
include /etc/tgt/xen/*.conf.
There are 2 types of storage devices:
backing-store - defines a virtual device on the target.
direct-store - defines a direct mapped device with the same properties as the physical device (such as VENDOR_ID , SERIAL_NUM, etc.)
initiator-address - allows connections only from the specify IP address. defaults to ALL if no "initiator-address" is specified
incominguser - define iscsi incoming authentication setting. if no "incominguser" is specified, it is not used.
outgoinguser - define iscsi outgoing authentication setting. if no "outgoinguser" is specified, it is not used.
example for a configuration file:
<target iqn.2007-04.com.example:san.monitoring>
backing-store /dev/san/monitoring
# if no "incominguser" is specified, it is not used
incominguser backup secretpass12
# defaults to ALL if no "initiator-address" is specified
initiator-address 192.168.1.2 </target>
<target iqn.2007-02.com.example:san.xen1>
backing-store /dev/san/xen1-disk1 # LUN1
direct-store /dev/san/xen1-disk2 # LUN2
initiator-address 192.168.1.2 # Allowed IP
initiator-address 192.168.5.6 # Allowed IP
incominguser user1 secretpass12
incominguser user2 secretpass23
outgoinguser userA secretpassA </target>
<target iqn.2007-02.com.example:san.xen2>
backing-store /dev/san/xen2 </target>
<target iqn.2007-06.com.example:san.vmware1>
backing-store /dev/san/vmware1 </target>
FILES
/etc/tgt/target.conf
