4. HDLM Operation

310

Check the correspondence between

HDevName

(the name of the logical device

file of the HDLM device) and

iLU

(the internal LU number) from the execution

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 18.

17. 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.

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

For details, refer to the Sun Cluster documentation.

4.5.4 Configuration Changes Such as Deleting a Logical Unit

This section describes the procedure for changing the configuration in any of the

following ways:

Deleting an LU

Changing an LU

#

Changing the host LUN
Changing, adding, or deleting a CHA port
Changing a target ID
Adding or replacing a Fibre Channel switch
Replacing, deleting, or adding an HBA

#

To change an LU, we recommend that you add a new LU and then delete the

existing one, rather than changing a LU in the storage system management

program. After adding the new LU, move data as required from the LU you are

deleting to the new LU. For details on adding a new LU, see 4.5.3 Adding a New

Logical Unit. If you use the storage system management program to change the

LDEV of the LU, an instance of the HDLM driver will not be created. As a result,

it may not be possible to verify the changed configuration until you create an

HDLM driver configuration definition file (

/kernel/drv/dlmfdrv.conf

).
