Installation guide

Installing XenServer

• a server providing a shared directory via iSCSI

Note

To be part of a resource pool, the XenServer Hosts and the server or servers providing the shared

iSCSI storage need to have static IP addresses.

Procedure 3.8. Basic procedure

1. Install XenServer Host software on server(s)

2. Install XenCenter on workstation(s)

3. Prepare the iSCSI storage

4. If necessary, enable your iSCSI device for multiple initiators

5. Run XenCenter and connect to XenServer Hosts

6. Choose one XenServer Host as a pool master and join other XenServer Hosts to its pool

7. Configure the iSCSI IQN for each XenServer Host

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

The details of how to set up iSCSI storage differ between the various iSCSI solutions on the market. In

general, though, you need to provide an iSCSI target on the SAN for the VM storage, and then configure

XenServer Hosts to be able to see and connect to it. This is done by providing a valid iSCSI Qualified Name

(IQN) to the iSCSI target and to the iSCSCI initiator on each XenServer Host.

Procedure 3.9. Prepare the iSCSI storage

1. Assign a virtual storage volume on the iSCSI SAN for VM storage

2. Create IQNs on the SAN for each XenServer Host that will use the storage

You can use either XenCenter or the CLI to configure the IQN for each XenServer Host and to create the

SR. The following describes using the CLI; see the XenServer Help for details on using XenCenter.

Warning

When using the XenCenter to create SRs for iSCSI and NetApp storage, any existing contents of

the volume will destroyed.

Procedure 3.10. To configure the iSCSI IQN for each XenServer Host via the CLI

1. In the Text Console, issue the command:

xe-set-iscsi-iqn <iSCSI-IQN>

Alternatively, the CLI can be used directly:

xe host-param-set uuid=<host-UUID> other-config-iscsi_iqn=<iSCSI-IQN>
