Linux: 自动发现与添加iscsi LUN

如题所示，下面的这个脚本是用来自动的发现与添加LUN的：

[root@oraclelab software]# cat /script/shared_storage_discovery_and_add.sh 
# This shell used to automatic discovery available lun and add it.
luns=`iscsiadm -m discovery -t sendtargets -p openfiler | cut -d " " -f2`
for lun in $luns
do
echo "========================"
echo "The LUN is: $lun"
echo "-------"
echo "Add LUN:"
echo "-------"
iscsiadm -m node -T $lun -p openfiler -l
echo "All Done."
done
[root@oraclelab software]#

[root@oraclelab software]# cat /script/shared_storage_discovery_and_add.sh

# This shell used to automatic discovery available lun and add it.

luns=`iscsiadm -m discovery -t sendtargets -p openfiler | cut -d " " -f2`

for lun in $luns

echo "========================"

echo "The LUN is: $lun"

echo "-------"

echo "Add LUN:"

echo "-------"

iscsiadm -m node -T $lun -p openfiler -l

echo "All Done."

done

[root@oraclelab software]#

对于上面的脚本，你也可以作出一些改动：
将其中的“openfiler”作为变量，在脚本执行时以参数的方式传入。

在我的环境中，这个脚本的工作状态的呈现如下：

[root@oraclelab software]# sh /script/shared_storage_discovery_and_add.sh 
========================
The LUN is: Oracle-DB-Center-LUN
-------
Add LUN:
-------
Logging in to [iface: default, target: Oracle-DB-Center-LUN, portal: 166.100.0.12,3260] (multiple)
Login to [iface: default, target: Oracle-DB-Center-LUN, portal: 166.100.0.12,3260] successful.
All Done.
