4. HDLM Operation
306
The following shows an example of executing the command:
# /usr/cluster/lib/sc/scsi -c inkeys -d /dev/rdsk/
c3t50060E80033A9902d2s2
Add the new LU to HDLM by following the steps in (3) Adding a New LU By
Restarting the Nodes (When Using Sun Cluster)beginning with step 5. Even when
you release the setup for Quorum devices and disk device groups, since the key
used for disk reservation will remain registered, you will need to restart the node
in non-cluster mode and unregister the key.
If the key is not displayed, perform the steps beginning with step 5.
5. Make sure that the logical device files for the sd or ssd devices are backed up.
When you execute the
dlmcfgmgr
utility in step 8 after executing the
dlmsetconf
utility in step 6, since the logical device files of the sd or ssd devices
to be managed by HDLM will be deleted, make sure that you back up these files
beforehand. 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.
6. 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 to be
managed by HDLM.
When the
dlmsetconf
utility is executed, the KAPL10242-I message will be
output.
If you respond by entering
y
, when you run the
dlmcfgmgr
utility in step 8 after
running the
dlmsetconf
utility, the logical device files of the sd or ssd devices
to be managed by HDLM will be deleted. If the logical device files are already
backed up, respond by entering
y
and running the
dlmsetconf
utility. If the files
are not backed up, respond by entering
n
, and then cancel processing for the
dlmsetconf
utility. Then, backup the logical device files 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, and then execute the
dlmsetconf
utility.
All sd or ssd devices connected to the host will be set as HDLM-managed devices.
