How to Add a Logical Volume

Use this procedure to add a logical volume to a cluster. This procedure assumes that your service provider created your logical volume. This procedure also assumes that all nodes are booted and are attached to the storage array.

This procedure provides the long forms of the Sun Cluster commands. Most commands also have short forms. Except for the forms of the command names, the commands are identical. For a list of the commands and their short forms, see Appendix A, Sun Cluster Object-Oriented Commands, in Sun Cluster 3.1 - 3.2 Hardware Administration Manual for Solaris OS.

Before You Begin

To perform this procedure, become superuser or assume a role that provides solaris.cluster.modify RBAC authorization.

1. On all nodes, update the /devices and /dev entries.

   # devfsadm

2. On each node connected to the storage array, use the appropriate multipathing software commands to verify that the same set of LUNs is visible to the expected controllers.

3. If you are running Veritas Volume Manager, update the list of devices on all nodes that are attached to the logical volume that you created in Step 2.

   See your Veritas Volume Manager documentation for information about how to use the vxdctl enable command. Use this command to update new devices (volumes) in your Veritas Volume Manager list of devices.

   Note –

   You might need to install the Veritas Array Support Library (ASL) package that corresponds to the array. For more information, see your Veritas Volume Manager documentation.

   If you are not running Veritas Volume Manager, proceed to Step 4.

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

   • If you are using Sun Cluster 3.2, use the following command:

     # cldevice populate

   • If you are using Sun Cluster 3.1, use the following command:

     # scgdevs

   If a volume management daemon such as vold is running on your node, and you have a CD-ROM drive that is connected to the node, a device busy error might be returned even if no disk is in the drive. This error is expected behavior.
