echo Server Name,vscsi,vscsi_err_recov,vscsi_path_to

for vscsi_attribute_list in `cat server`
do
for vcs in `ssh $vscsi_attribute_list lsdev -C |grep vscsi |awk '{print $1}'`
do
vscsi_err_recov=`ssh $vscsi_attribute_list lsattr -El $vcs |grep vscsi_err_recov |awk '{print $2}'`
vscsi_path_to=`ssh $vscsi_attribute_list lsattr -El $vcs |grep vscsi_path_to |awk '{print $2}'`
echo $vscsi_attribute_list,$vcs,$vscsi_err_recov,$vscsi_path_to
