[root@lgdrm1109 ~]# iscsiadm -m discovery -t sendtargets -p [fd00:206:553::7]:3260 [fd00:206:553::3]:3260,1 iqn.2008-05.com.xtremio:001e679fa196 [fd00:205:553::3]:3260,1 iqn.2008-05.com.xtremio:001e679fa196 [fd00:206:553::4]:3260,1 iqn.2008-05.com.xtremio:001e679fa197 [fd00:205:553::4]:3260,1 iqn.2008-05.com.xtremio:001e679fa197 [fd00:206:553::7]:3260,1 iqn.2008-05.com.xtremio:001e679fb5f6 [fd00:205:553::7]:3260,1 iqn.2008-05.com.xtremio:001e679fb5f6 [fd00:206:553::8]:3260,1 iqn.2008-05.com.xtremio:001e679fb5f7 [fd00:205:553::8]:3260,1 iqn.2008-05.com.xtremio:001e679fb5f7 Y.
