How to map iSCSI interface of XenServer 6.0.2 VNX 5300

How to map iSCSI interface of XenServer and 5.6, 6.0.2 VNX 5300

First define storage interface on XenServer and for that choose configure under “Management Interface ” and then select “New Interface” . Now specify the name and then choose the NIC which will be configure for storage traffic. Supply IP address. This needs to be repeated for all the interface which is connected to the storage.

Once this is done then perform discovery of the nic for the logging into EMC. This can be perform via CLI as well as via XenCenter.

My experience is to use XenCenter

To perform via XenCenter select new storage and choose “Software iSCSI”. Choose “Name” and then under location provide information as follows :

Target host: This will be IP address of target Storage Processor or controller . Specify all the IP address with ,

XenServer New Storage Repo

Target IQN: Here you will find IQN of the target storage processor . If it has 4 ports then you will see 4 IQN. We need to choose the one which is highlighted (*)

This will log all the targets on the EMC VNX box to mapped .

From the command line following needs to be run from the host in order to login.

Once all the message says successfully login , open EMC Unishpere and select “Connectivity status ” on left hand side under “Hosts “. This will popup Host initiators window. You will find one name with just IQN as shown below. This is the new targets which has logged in . Select “Edit ” from bottom and then provide information about “host name” “IP address” . IP address is of XenServer management IP . Make sure you choose initiator type as “clarion open ” and Fail Over mode as “ALUA 4”. ALUA is the latest fail over mode as per EMC.
