3.5.1 Preparations for a new installation of HDLM

The following explains the operations you need to perform before new installation of HDLM.

For a FC connection, check the topology (Fabric, AL, etc.) and perform setup as appropriate.

To prepare for HDLM installation:

1. Use a single cable to connect the host to the storage subsystem (single path configuration).
   Using multiple paths to connect a host and a storage subsystem (a multi-path configuration) before installing HDLM may cause unstable Windows operation. Make sure that you use a single-path configuration until HDLM installation finishes.
   Figure 3-2 Single path configuration and multi-path configuration shows a single path configuration and a multi-path configuration.

2. Set up the storage subsystem.
   Assign an LU to each port.
   Change the settings of the storage subsystem according to the Hardware Notes document that is supplied with HDLM.
   
3. Install the HBAs onto the host.
   Install all the HBAs 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 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, whether or not paths exist.
   The settings depend on the topology to be used. For details on how to set up the BIOS, see the documentation for the HBA.
   
6. Install Windows, and any non-HDLM driver.
   Install Windows and any non-HDLM driver according to the documentation for each product.
   
7. Set up the HBAs.
   See the Hardware Notes provided with HDLM and the relevant HBA manual to complete the required setup.
   
8. If your configuration uses an IP-SAN, install and set up the iSCSI initiator (iSCSI software or HBA).
   For details on setup, see the iSCSI initiator documentation, the Hardware Notes provided with HDLM, or the storage subsystem documentation.
   
9. Prepare the LUs.
   For the LUs you want to use, write signatures, create partitions, and then format. Since the system is in the single path configuration, no problem will occur even if you write signatures for all the LUs.
   
10. Restart the host.
11. Confirm that the host is operating normally.
