Create a Volume

Perform these steps to create a volume (iSCSI LUN) using the Oracle ZFS Storage Appliance browser user interface (ZFSSA BUI).

  1. On a web UI, use the opc user account to log into the ZFSSA head where you want to create the storage volume (LUN).

    You can access the BUI at https://zfssa_head_ip:215.

  2. Identify and make note of the ZFSSA network interface information for the volume you want to create.

    Storage volumes (iSCSI LUNs) are provided over network devices. When configuring a volume, you must supply the appropriate network device over which the volume will be served. Oracle SPARC Model 300 Service provides storage access over vnic5 (corresponding to head 1) and vnic7 (corresponding to head 2) of the ZFSSA. You must identify which of these devices you wish to serve the volume over when configuring the volume.

    Complete these steps to identify the network interface information for the volume (LUN):

    1. Navigate from the Configuration > Network screen of the BUI, then select the Configuration tab.
    2. Locate the network for the volume from the 'Interfaces' list.

      The network you choose will vary depending on which of the two ZFSSA heads is used for the volume (LUN).

      • Head 1 is associated with the interface named opczs3-2-1-store-aggr.

      • Head 2 is associated with the interface named opczs3-2-2-store-aggr.

    3. Make note of the following information and keep it accessible for upcoming steps.

      In this example, head 1 is used for the volume, so let's make note of these values:

      • Interface name: opczs3-2-1-store-aggr

      • VNIC shortname: vnic5

      • IP address: 192.168.50.36

  3. Define an iSCSI target.

    Create a target group to enable the volumes (targets) to be shared with only specific initiators (one or more compute instances).

    Complete these steps to create a target for the volume (LUN).

    1. Navigate from the Configuration > SAN screen of the BUI, select the iSCSI tab, and click the (+) button next to the Targets label, as shown here.

    2. When the 'Create iSCSI Target' window appears, enter values for the iSCSI target and click OK, as shown in this example.
      • 'Alias' is an unambiguous reference name for administrators to use to refer to the disk.

      • If additional security is required, select an 'Initiator authentication mode' and the associated target name and secret. This example does not enable CHAP or RADIUS.

      • 'Network interface' is the name that was listed for the ZFSSA head for the volume (LUN) earlier in this procedure (vnic5).

  4. Create a Target Group to which the target will belong.

    Targets in the same target group will be visible to the same initiator(s). Complete these steps to create a target group:

    1. Navigate from the Configuration > SAN screen of the BUI, select the iSCSI tab.
    2. Drag the target you want to add to a target group from the 'Targets' list to a group under the 'Target Groups' list.

      You can drag a target to an existing group or to the new group area to create a new group.


      Note -  Drag targets by floating the mouse over the target. When a drag handle appears to the left of the target, click and drag it to the desired target group.

      In this example, the new group is created with the default name targets-0. You can change the default name, as we did in our example, by clicking the edit symbol that appears to the right of the name when you hover the mouse over the name. In the example, the group is renamed to Example Target Group 1.

    3. Click Apply to create the volume (LUN).
