A Software iSCSI SR uses a shared Logical Volume Manager (LVM) on a SAN attached LUN over iSCSI. iSCSI is supported using the open-iSCSI software iSCSI initiator or by using a supported iSCSI Host Bus Adapter (HBA).
Note that dynamic multipathing support is available for iSCSI storage repositories. By default, multipathing uses round robin mode load balancing, so both routes will have active traffic on them during normal operation. You enable and disable storage multipathing in XenCenter via the Multipathing tab on the server's Properties dialog; see Storage Multipathing.
|Target Host||The IP address or DNS name of the iSCSI target.|
|Use CHAP||If the iSCSI target is configured to used CHAP authentication, select the Use CHAP check box and fill in the details:
|Target IQN||To specify the iSCSI target IQN, click the Discover IQNs button and then choose an IQN from the Target IQN list.
Important: Important The iSCSI target and all servers in the pool must not have the same IQN set. It is imperative that every iSCSI target and initiator have a unique IQN. If a non-unique IQN identifier is used, data corruption can occur and/or access to the target may be denied.
|Target LUN||To specify the LUN on which the storage repository will be created, click the Discover LUNs button and then choose a LUN from the Target LUN list.
Each individual iSCSI storage repository must be contained entirely on a single LUN (Logical Unit Number), and may not span more than one LUN. If the LUN already contains an SR, you can either use the existing SR or you can replace the existing SR with a new one, destroying any data present on the disk.
