Preparations for a New Installation of HDLM
The following explains what you need to do before performing a new
installation of HDLM.
For an FC connection, check the topology (Fabric, AL, etc.) and perform an
appropriate setup.
To prepare for an HDLM installation:
1. Use a single cable to connect the host to the storage system.
Using multiple paths to connect a host to a storage system before
installing HDLM might result in unstable Windows operations. Make sure
that you only use a single-path configuration until the HDLM installation is
done.
The following figure shows a single path configuration and a multi-path
configuration.
Figure 3-2 Single Path Configuration and Multi-path Configuration
2. Set up the storage system.
Assign an LU to each port.
To change the settings of a storage system, follow the maintenance
documentation for that particular storage system.
3. Install the HBAs onto the host.
Install as many HBAs as you want to use.
In a cluster configuration, make sure that the manufacturer and model of
the HBA is the same for all the hosts that make up the cluster. Also, make
sure that the versions of the HBA micro-programs are the same.
4. Set up the switches.
For details on how to set up a switch, see the documentation for the
particular switch. This step is unnecessary if you do not use a switch.
5. Set up the BIOS for the HBAs.
Set up the BIOS for all the HBAs, regardless of whether paths exist.
Different settings are used for different topologies. For details on how to
set up the BIOS, see the HBA documentation.
