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.

(3) Changing a Non-HDLM-Managed Device to an HDLM-Managed Device (For

Dynamic Reconfiguration)

Note

• Dynamic reconfiguration cannot be performed when using VxVM because

the host must be restarted in order to use (in VxVM) an LU that was changed

from a non-HDLM-managed device to an HDLM-managed device. Perform

the procedure (2) Changing a Non-HDLM-Managed Device to an

HDLM-Managed Device (When the Node Must Be Restarted) in

4.5.6 Specifying Whether a Logical Unit Is To Be Managed by HDLM

(When Using Sun Cluster).

• For details on the precautions for the

dlmcfgmgr

utility for managing the

HDLM configuration, see 7.3 The dlmcfgmgr Utility for Managing the

HDLM Configuration.

To change a non-HDLM-managed device to an HDLM-managed device:
1.

Check the LU to be managed by HDLM.
You can check the LU by using the

format

command. Figure 4-16: Example

of executing the format command shows an example of executing the

format

command. The shaded portion represents the LU to be managed by HDLM.
