Sun Cluster 3.0-3.1 With Sun StorEdge T3 or T3+ Array Manual for Solaris OS

ProcedureHow to Create a Logical Volume

Use this procedure to create a logical volume from unassigned storage capacity.

Note –

Sun storage documentation uses the following terms:

This manual uses logical volume to refer to all such logical constructs.

Before You Begin

This procedure relies on the following prerequisites and assumptions.

  1. Follow the instructions in your storage device's documentation to create and map the logical volume. For a URL to this storage documentation, see Related Documentation.

    • Completely set up the logical volume. When you are finished, the volume must be created, mapped, mounted, and initialized.

    • If necessary, partition the volume.

    • To allow multiple clusters and nonclustered nodes to access the storage device, create initiator groups by using LUN masking.

  2. Are you using multipathing?

  3. Are any devices that are associated with the volume you created at an unconfigured state?

    # cfgadm -al | grep disk
    • If no, proceed to Step 4.

    • If yes, configure the Traffic Manager paths on each node that is connected to the storage device.

      cfgadm -o force_update -c configure controllerinstance

      For the procedure about how to configure Traffic Manager paths, see the Sun StorEdge Traffic Manager Installation and Configuration Guide.

  4. On one node that is connected to the storage device, use the format command to label the new logical volume.

  5. From any node in the cluster, update the global device namespace.

    # scgdevs

    Note –

    You might have a volume management daemon such as vold running on your node, and have a CD-ROM drive connected to the node. Under these conditions, a device busy error might be returned even if no disk is in the drive. This error is expected behavior. You can safely ignore this error message.

  6. To manage this volume with volume management software, use the appropriate Solstice DiskSuite/Solaris Volume Manager or VERITAS Volume Manager commands to update the list of devices on all nodes that are attached to the new volume that you created.

    For more information, see your Solstice DiskSuite/Solaris Volume Manager or VERITAS Volume Manager documentation.
