Citrix Systems 6.1.0 XenServer Hosts with Shared iSCSI Storage, Configuring your iSCSI storage

2.Under Virtual disk storage, choose NFS VHD as the storage type. Choose Next to continue.

3.Enter a name for the new SR and the name of the share where it is located. Click Scan to have the wizard scan for existing NFS SRs in the specified location.

Note:

The NFS server must be configured to export the specified path to all XenServer hosts in the pool.

4.Click Finish.

The new SR appears in the Resources pane, at the pool level.

Creating an SR on the NFS share at the pool level using the xe CLI:

1.Open a console on any XenServer host in the pool.

2.Create the storage repository on server:/path by entering the following:

xe sr-create content-type=user type=nfs name-label=<sr_name=>\ shared=true device-config:server=<server>\ device-config:serverpath=<path>

The device-config-serverargument refers to the name of the NFS server and the device- config-serverpathargument refers to the path on the server. Since shared is set to true, the shared storage is automatically connected to every host in the pool and any hosts that subsequently join are also connected to the storage. The UUID of the created storage repository is printed to the console.

3.Find the UUID of the pool by using the pool-listcommand.

4.Set the new SR as the pool-wide default by entering the following:

xe pool-param-set uuid=<pool_uuid> \ default-SR=<storage_repository_uuid>

As shared storage has been set as the pool-wide default, all future VMs will have their disks created on this SR.

4.2.2. XenServer Hosts with Shared iSCSI Storage

Basic hardware requirements:

•Two or more 64-bit x86 servers with local storage

•One or more Windows workstation(s), on the same network as the XenServer hosts

•A server providing a shared directory over iSCSI

High-level procedure:

1.Install the XenServer host software on the servers.

2.Install XenCenter on the workstation(s).

3.Connect XenCenter to the XenServer hosts.

4.Create your pool of XenServer hosts.

5.Configure the iSCSI storage.

6.If necessary, enable multiple initiators on your iSCSI device.

7.If necessary, configure the iSCSI IQN for each XenServer host.

8.Create an SR on the iSCSI share at the pool level.
