4. HDLM Operation

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
).
