Citrix* XenServer* 5.5.0 Installation Guide -
Intel® Server Board S3420GP
21
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 the 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. In general,
provide an iSCSI target on the SAN for the VM storage, 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.
Prepare the iSCSI Storage
To prepare the iSCSI storage, perform these steps:
1) Assign a virtual storage volume on the iSCSI SAN for VM storage.
2) Create IQNs on the SAN for each XenServer* host using the storage.
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 menu for details about how to use
XenCenter* to configure the IQN.
Warning: When using the XenCenter* to create SRs for iSCSI and NetApp* storage, any existing
contents of the volume will destroyed.
Configure the iSCSI IQN for Each XenServer* Host via the CLI
To configure the iSCSI IQN for each XenServer* host via the CLI, perform these steps:
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>
2) Repeat step 1 for each XenServer* host in the pool.
