You must install the host adapters on the host before the storage system is attached. You also need to discover and write down the WWNs of the adapters to be connected to the storage system.
For assistance with specific configuration issues related to the storage system, contact customer support.
- Follow the instructions in the vendor documentation for preparing your hosts, HBAs, CNAs, NICs, and iSCSI initiators for use with the storage system or contact the vendor's technical support.
For iSCSI specifications and requirements, see the VSP One Block Hardware Guide for your storage system model.
- Verify that the host adapters are supported by the storage system.
For details, see the Hitachi Vantara Product Compatibility Guide: https://compatibility.hitachivantara.com
- Install and verify the adapters.
For details about installing the adapter and using the utilities for the adapter, see the user documentation for the adapter.
Note:- Do not connect OFC-type FC interfaces to the storage system.
- If a switch or adapter with a 1-Gbps transfer rate is used, configure the device to use a fixed 1-Gbps setting instead of Auto Negotiation. Otherwise, it may prevent a connection from being established. However, the transfer speed of CHF port cannot be set as 1 Gbps when the CHF model type is 8US/8UFC/16UFC. Therefore 1-Gbps adapter and switch cannot be connected.
- Configure the adapter.
Use the setup utilities to configure the adapters to be connected to the storage system. The minimum requirements for configuring the adapters for operation with the storage system are:
- I/O timeout value (TOV): The disk I/O timeout value (TOV) requirement for the storage system is 60 seconds (0x3c hex).
- Queue depth: See Host queue depth for the recommended queue depth settings. You can adjust the queue depth later as needed to optimize the I/O performance of the devices.
- BIOS: The BIOS might need to be disabled to prevent the system from trying to boot from the storage system.
Use the same settings and device parameters for all devices on the storage system. Several other parameters (for example, FC fabric) might also need to be set. See the user documentation for the host adapter to determine whether other options are required to meet your operational requirements. See Host queue depth for queue depth settings.
- Record the WWNs of the adapters.
You will need to enter these WWNs when you configure the new hosts on your storage system.
For details about finding the WWN of an adapter, see the user documentation for the adapter.
