Hitachi Dynamic Link Manager Software Users Guide for Solaris

Have the HDLM drivers on all nodes in the cluster recognize the LU newly
recognized by the node, and make the configuration the same for each
node.
To add a new LU:
1. Set up the storage system and switch so that Solaris recognizes the LU.
2. Check the LU newly recognized by the node and its disk label.
You can check the LU and verify that the disk label is specified by using
the format command. The following figure shows an example of the
format command. The shaded portion represents the LU newly
recognized by the node.
Figure 4-2 Example of executing the format command
In the above execution example, when you specify an LU, the message
Disk not labeled. Label it now? will be output if a disk label has not
been specified. In this case, enter y and specify a disk label.
3. If setup is performed for Quorum devices and disk device groups, on an
LU newly recognized by the node, release these settings.
When you unregister the SDS or SVM diskset, the diskset data will be
deleted so first back up any necessary data. For details on how to remove
settings for Quorum devices and VxVM disk groups, see
