results of the command, compare the correspondence with the correspondence

that took place before the HDLM installation, and then re-register HDLM devices

with the programs that will use them.
If you want to use volume management software to create a file system on an

HDLM-managed device, skip to step 24.

23. Perform registration for the disk device group.

If you are using VxVM, see 3.13.5 Linking VxVM and Sun Cluster.
If you are using SDS, see (2) To Use a Shared Diskset of 3.14.2 Registering

HDLM Devices.
If you are using SVM, see (2) To Use a Shared Diskset of 3.15.2 Registering

HDLM Devices.

24. Create the file system and set up the global mount as necessary.

For details, refer to the Sun Cluster documentation.

(4) Adding a New LU Via Dynamic Reconfiguration (When Using Sun Cluster)

Note

• A new LU cannot be added via dynamic reconfiguration when you are using

VxVM, because the host must be restarted in order to use (in VxVM) an LU

that has been newly added to HDLM. Perform the procedure described in

(3) Adding a New LU By Restarting the Nodes (When Using Sun Cluster).

• For details on the precautions for the

dlmcfgmgr

utility, see 7.3 The

dlmcfgmgr Utility for Managing the HDLM Configuration.

To add a new LU:
1.

Set up the storage system and switch so that Solaris recognizes the LU.

Check the LU newly recognized by the node.
Use the

format

command to check the LU. Figure 4-3: Example of executing

the format command shows an example of executing the

format

command. The

shaded portion represents the newly recognized LU.
