9. Make sure that the logical device files for the sd or ssd device are backed up.
When you restart the node, with the reconfiguration option specified, after
running the
dlmsetconf
utility in the next step (step 10), the logical device files
of the sd or ssd device to be managed by HDLM will be deleted. Make sure that
these files are backed up before you execute the
dlmsetconf
utility to restart
the node. For details on how to back up files, see step 4 in (1) Performing
Operations on Devices to Be Managed by HDLM of 3.5.1 Preparations for a
New Installation of HDLM.
10. Use the following
dlmsetconf
utility to create the HDLM driver configuration
definition file (
/kernel/drv/dlmfdrv.conf
) and the HDLM driver
unconfiguration definition file (
/opt/DynamicLinkManager/config/
dlmfdrv.unconf
).
# /opt/DynamicLinkManager/bin/dlmsetconf
The device mentioned in 2.1 Devices Managed by HDLM will be set as an
HDLM-managed device.
When the
dlmsetconf
utility is executed, the KAPL10242-I message will be
displayed prompting you to confirm the deletion of the logical device files for the
sd or ssd device.
If you respond by entering
y
, and then execute the
dlmsetconf
utility and restart
the node, with the reconfiguration option specified, the logical device files of the
sd or ssd device to be managed by HDLM will be deleted. If the logical device
files are already backed up, enter
y
and execute the
dlmsetconf
utility. If the
files are not backed up, respond by entering
n
, and then cancel processing for the
dlmsetconf
utility. In this case, back up the logical device files and execute the
dlmsetconf
utility, by referring to step 4 in (1) Performing Operations on
Devices to Be Managed by HDLM of 3.5.1 Preparations for a New Installation
of HDLM.
When the
dlmsetconf
utility is executed and then the host is restarted with the
reconfiguration option specified, all sd or ssd devices connected to the host will
be set to be managed by HDLM.
Note
Restart the nodes simultaneously as shown in steps 12 and 13, after the setup
for LUs newly recognized on all nodes has completed.
11. If you are using VxVM, you need to disable, from VxVM, any devices (such as
sd or ssd devices) other than the HDLM devices corresponding to the added LU.
Specify settings according to (2) Removing Devices from VxVM on a Controller
Basis or (3) Removing Devices From VxVM on a Path Basis of 3.13.3 Removing
