these devices.
To use an HDLM-managed device with a file system created by using volume

management software, perform step 34.
To use an HDLM-managed device with a file system created without using

volume management software, perform steps 35 to 37.

34. Register 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 in 3.14.2 Registering

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

HDLM Devices.

35. In Sun Cluster, to create a new shared file system, create it in any

HDLM-managed device from a desired node.
The following shows an example of executing the command:


host1# newfs /dev/global/rdsk/d5s0

36. Execute the following command to create a directory for mounting on each node:

The following shows an example of executing the command:

host1# mkdir -p /global/mntpt
host2# mkdir -p /global/mntpt

37. On the desired node, mount the file system. The following shows an example of

executing the command:

host1# mount -g /dev/global/dsk/d5s0 /global/mntpt

3.5.5 Using the HDLM Device Unconfiguration Function When

Performing a New Installation of HDLM

You can use the HDLM device unconfiguration function to remove Hitachi storage

system devices from HDLM management on a per-LU basis. This section explains

how to use the HDLM device unconfiguration function.
1.

To remove an LU from HDLM management, use a text editor to edit the HDLM

driver unconfiguration definition file (

/opt/DynamicLinkManager/config/

dlmfdrv.unconf

).

In the lines that define the LU that is to be removed from HDLM management,

delete the hash mark (

#

) in front of the

LDEV

property line. Do not change

anything else. Figure 3-4: Example of an /opt/DynamicLinkManager/config/
