  If your host cannot access Hitachi storage, there may be a communication failure. Here's what you can do: 1. If using Fibre Channel, check the port activity LED on the Fibre Channel data ports. 2. Ensure all Fibre Channel cables are securely connected. 3. If using iSCSI, ping the array from the host to verify communication at the correct IP address. 4. Check other network devices like routers or switches for issues.
