3. Creating an HDLM Environment

17. Specify the devices that are to be excluded from management by HDLM, if there
are any.
This step is unnecessary if you want HDLM to manage all applicable devices.
Devices that cannot be managed by HDLM are automatically removed from the
HDLM driver configuration definition file. For details on devices that cannot be
managed by HDLM, see 2.1 Devices Managed by HDLM.
To remove devices from HDLM management, edit the HDLM driver
unconfiguration definition file (
/opt/DynamicLinkManager/config/
dlmfdrv.unconf
).
For details on how to perform this setting, see 3.5.5 Using the HDLM Device
Unconfiguration Function When Performing a New Installation of HDLM.
Note
Set the boot disk in the post-migration environment as an HDLM-managed
device if, before this step, you executed the procedure described in
(2) Migration by Installing HDLM in the Existing Local Boot Disk
Environment in 3.6.2 Procedure for Configuring a Boot Disk Environment.
Note the following if, before this step, you executed the procedure described
in (3) Migration by Installing HDLM in the Existing Boot Disk Environment
or (4) Migration by Building a New Pre-Migration Environment in
3.6.2 Procedure for Configuring a Boot Disk Environment:
- If the boot disk in the pre-migration environment is an HDLM-managed
device, change the setting to exclude it from HDLM management.
- Set the post-migration boot disk as an HDLM-managed device.
18. When you use VxVM, from VxVM disable the devices that you do not need to
access.
Specify settings as shown in (2) Removing Devices from VxVM on a Controller
Basis or (3) Removing Devices From VxVM on a Path Basis in 3.13.3 Removing
Devices from VxVM.
19. Stop all nodes that comprise the cluster.
If one or more keys were displayed at step 6 and the node was started in
non-cluster mode at step 8, execute the following command on all nodes:
# shutdown -g0 -y -i0
If the nodes were started in cluster mode, execute the following command on any
one node:
# /usr/cluster/bin/scshutdown -g0 -y
