Problems with ISCSI shared luns after cloning Solaris servers

Hi,

just a little note, if you are configuring ISCSI shared luns for several initiators, and you have cloned your servers from a golden image or similar, you have to be careful because the IQN could be duplicated, giving all kinds of hangs when the hosts access the iscsi shared lun.

You can check the IQN of the host with:

[root@vm1:/]# iscsiadm list initiator-node
Initiator node name: iqn.1986-03.com.sun:01:eaee30f2ffff.4e7470c1 --> it's the same for vm1 and vm2
Initiator node alias: vm2
[root@vm2:/]# iscsiadm list initiator-node
Initiator node name: iqn.1986-03.com.sun:01:eaee30f2ffff.4e7470c1 ---> the same!!
Initiator node alias: vm2

Don't know if the best way but I fixed it changing the IQN in one of the hosts:

[root@vm1:/]# iscsiadm modify initiator-node -N iqn.1986-03.com.sun:01:eaeec2f5ffff.4c936e1b
[root@vm1:/]#iscsiadm modify initiator-node -A vm1
[root@vm1:/]# iscsiadm list initiator-node
Initiator node name: iqn.1986-03.com.sun:01:eaeec2f5ffff.4c936e1b
Initiator node alias: vm1

All working smoothly now!.
