3.4.2 Notes on Installation
You cannot edit the HDLM driver configuration definition file (
/kernel/drv/
dlmfdrv.conf
). To change an HDLM-managed device to a
non-HDLM-managed device, use the HDLM device unconfiguration function of
the HDLM device. For details on the HDLM device unconfiguration function, see
3.5.5 Using the HDLM Device Unconfiguration Function When Performing a
New Installation of HDLM or 4.5.5 Specifying Whether a Logical Unit Is To Be
Managed by HDLM (When Not Using Sun Cluster).
When you install HDLM, a device file dedicated to HDLM is created in the
/
dev/dlm
directory. Do not use this device file.
Install any other applications after completing the HDLM environment setup.
If Hitachi Path Manager is installed on the host, uninstall it and restart the host
before installing HDLM. For details on uninstalling Hitachi Path Manager, see
the Hitachi Path Manager manual.
If you are using HDLM 05-00 or earlier, uninstall the program while referring to
3.17 Uninstalling HDLM, and then perform a new installation of HDLM 6.5.1.
A license key is required to install HDLM.
To update the license before upgrading or reinstalling HDLM, execute the
dlnkmgr
command's
set
-lic
operation. The license key specified in the
license key file or the type of input license key determines the expiration of the
license key. For details on license key types and the
set
operation, see 6.6 set
(Sets Up the Operating Environment).
When you install a license by specifying the
set
-lic
operation, you must
execute one command at a time. If you execute multiple commands at the same
time, a core file might be created and a message might be displayed.
If a message is output, execute the
view
-sys
operation to make sure that the
license has been installed correctly.
An upgrade installation of HDLM does not update the following files:
The existing information about the driver configuration and HDLM settings is
still preserved after the upgrade installation.
• The HDLM driver configuration definition file (
/kernel/drv/
dlmfdrv.conf
)
• The HDLM nexus driver configuration definition file (
/kernel/drv/
dlmndrv.conf
)
• The HDLM function configuration file (
/opt/DynamicLinkManager/
config/dlmmgr.xml
)
