cluster 2 nodes and iscsi storage

[Smile]

Hi,
I have 2 nodes (IBM x3550 M4) with PVE 3.4 and IBM v3700 storage.
Both nodes are connected to each iscsi controller (a total of 2 ports for each node).

I followed this guide: http://pve.proxmox.com/wiki/Storage_Model#LVM_Groups_with_Network_Backing
to achieve iscsi lun for kvm, so I'll be able to migrate from one node to each other.
The problem is that I can't use migrate, it always fail with an error "storage 'iscsi-node1' is not available on node 'node2'".
Both nodes have an access to same iscsi lun.

node1 iscsi sessions:

root@node1:~# iscsiadm -m session
tcp: [1] 10.0.1.10:3260,3 iqn.1986-03.com.ibm:2145.nativstorage.node1
tcp: [2] 10.0.2.10:3260,4 iqn.1986-03.com.ibm:2145.nativstorage.node1

node2 iscsi sessions:

root@node2:~# iscsiadm -m session
tcp: [1] 10.0.2.20:3260,4 iqn.1986-03.com.ibm:2145.nativstorage.node2
tcp: [2] 10.0.1.20:3260,3 iqn.1986-03.com.ibm:2145.nativstorage.node2

I think the problem is that kvm-node1 base is iscsi-node1 on both of my nodes, but I can't change it to iscsi-node2 because it will replicate it to node1.
How can I solve this problem?

I just deleted base iscsi-node1:0.0.2.scsi-kvm from storage.cfg, now it's working fine.
Is it safe to do so?
