<title>Adding Primary Stroage</title>

<para>When you create a new zone, the first primary storage is added as part of that procedure. You can add primary storage servers at any time, such as when adding a new cluster or adding more servers to an existing cluster.</para>

<warning><para>Be sure there is nothing stored on the server. Adding the server to &PRODUCT; will destroy any existing data.</para></warning>

<orderedlist>

<listitem><para>Log in to the &PRODUCT; UI (see <xref linkend="log-in" />).</para></listitem>

<listitem><para>In the left navigation, choose Infrastructure. In Zones, click View More, then click the zone in which you want to add the primary storage.</para></listitem>

<listitem><para>Click the Compute tab.</para></listitem>

<listitem><para>In the Primary Storage node of the diagram, click View All.</para></listitem>

<listitem><para>Click Add Primary Storage.</para></listitem>

<listitem>

<para>Provide the following information in the dialog. The information required varies depending on your choice in Protocol.</para>

<itemizedlist>

<listitem><para><emphasis role="bold">Pod.</emphasis> The pod for the storage device.</para></listitem>

<listitem><para><emphasis role="bold">Cluster.</emphasis> The cluster for the storage device.</para></listitem>

<listitem><para><emphasis role="bold">Name.</emphasis> The name of the storage device.</para></listitem>

<listitem><para><emphasis role="bold">Protocol.</emphasis> For XenServer, choose either NFS, iSCSI, or PreSetup. For KVM, choose NFS or SharedMountPoint. For vSphere choose either VMFS (iSCSI or FiberChannel) or NFS.</para></listitem>

<listitem><para><emphasis role="bold">Server (for NFS, iSCSI, or PreSetup).</emphasis> The IP address or DNS name of the storage device.</para></listitem>

<listitem><para><emphasis role="bold">Server (for VMFS).</emphasis> The IP address or DNS name of the vCenter server.</para></listitem>

<listitem><para><emphasis role="bold">Path (for NFS).</emphasis> In NFS this is the exported path from the server.</para></listitem>

<listitem><para><emphasis role="bold">Path (for VMFS).</emphasis> In vSphere this is a combination of the datacenter name and the datastore name. The format is "/" datacenter name "/" datastore name. For example, "/cloud.dc.VM/cluster1datastore".</para></listitem>

<listitem><para><emphasis role="bold">Path (for SharedMountPoint).</emphasis> With KVM this is the path on each host that is where this primary storage is mounted. For example, "/mnt/primary".</para></listitem>

<listitem><para><emphasis role="bold">SR Name-Label (for PreSetup).</emphasis> Enter the name-label of the SR that has been set up outside &PRODUCT;.</para></listitem>

<listitem><para><emphasis role="bold">Target IQN (for iSCSI).</emphasis> In iSCSI this is the IQN of the target. For example, iqn.1986-03.com.sun:02:01ec9bb549-1271378984.</para></listitem>

<listitem><para><emphasis role="bold">Lun # (for iSCSI).</emphasis> In iSCSI this is the LUN number. For example, 3.</para></listitem>

<listitem><para><emphasis role="bold">Tags (optional).</emphasis> The comma-separated list of tags for this storage device. It should be an equivalent set or superset of the tags on your disk offerings..</para></listitem>

</itemizedlist>

<para>The tag sets on primary storage across clusters in a Zone must be identical. For example, if cluster A provides primary storage that has tags T1 and T2, all other clusters in the Zone must also provide primary storage that has tags T1 and T2.</para>
