Attaching a new block storage to XenServer Cluster

in previous chapter we created a XenServer cluster and share a common object storage between both XenServer to place OS ISO files for VM installation , we can not place VM\instance hard drive on object storage

so now we need a block storage ( on AWS world we called them as EBS volume ) which is accessible \ attached  from both cluster node then our VM can become online from other xenserver in case any problem or power failure of current host .

 there are number of type EBS storage available on AWS but in this lab we are going to use ISCSI server for our block storage and i am going to explain how to attach a ISCSI hard drive \ block storage to XenServer cluster
